Concurrent with efforts to establish national and regional biorepositories in Africa is widespread endorsement of ethics committees as stewards of the interests of individual donors and their communities. To date, ethics training programs for IRB members in Botswana have focused on ethical principles and international guidelines rather than on the ethical dimensions of specific medical technologies and research methodologies. Little is known about the knowledge and concerns of current and prospective IRB members in Botswana with respect to export, reuse, storage, and benefit-sharing of biospecimens.
This qualitative study examined perspectives of IRB members in Botswana about the collection and use of biospecimens in research. Forty-one IRB members representing five committees in Botswana participated in discussions groups in March 2013. Transcriptions of audiotapes and field notes were analyzed to identify issues of concern that might be alleviated through education and capacity-building, and areas that required ongoing discussion or additional regulatory guidance.
Areas of concern included lack of understanding among patients and providers about the use of biospecimens in clinical care and research; reuse of biospecimens, particularly issues of consent, ownership and decision-making; export of specimens and loss of control over reuse and potential benefits; and felt need for regulatory guidance and IRB-member training. Local belief systems about bodily integrity and strong national identity in the construct of benefits may be at odds with initiatives that involve foreign biorepositories or consider such collections to be global public goods.
Education is needed to strengthen IRB-member capacity to review and monitor protocols calling for the collection and use of biospecimens, guided by clear national policy on priority-setting, partnerships, review, and oversight. Engagement with local stakeholders is needed to harmonize fundamentally different ways of understanding the human body and community identity with the aims of contemporary biomedicine.

Advances in pharmacogenetics and genomics research and their potential to yield public health benefits have contributed to the growing use of human biological specimens (HBS) in research and the establishment, mainly in developed countries, of large-scale biorepositories. Samples from African populations have been included in several public genome reference collections, among them the International HapMap Project, The 1000 Genomes Project, and the Malaria Genomic Epidemiology Network [1–3]. In the past decade, several African biorepositories have been established, including The Gambia National DNA Bank, the African Institute of Biomedical Science and Technology (Zimbabwe) and the biobank at the University of Kwazulu-Natal’s African Centre for Health and Population Studies in South Africa [4–6].
Recently, international efforts to establish a number of regional pan-African biorepositories have gained momentum, largely under the aegis of the Human Heredity and Health in Africa Initiative (H3Africa) . Four pilot regional biobanks are in development- two in South Africa and one each in Nigeria and Uganda. The H3Africa Initiative centers on a ‘hub-and-spoke’ model, with biobanks serving as regional biorepositories of specimens collected as part of research initiatives situated in universities and centers across Africa . It is anticipated that all H3Africa research projects will begin to send a portion or all of their samples to one of these biobanks starting in 2014 .
Biobanking introduces highly complex ethical challenges, particularly in Africa where limited access toresearch ethics education and familiarity with drug/treatment development may make it difficult for research participants to understand the risks and the potential benefits associated with genetic research and where regulatory guidance on collection, use, export, ownership and storage of biospecimens is scant [10–12]. Ethics reviewers may lack sufficient understanding about these technologies or have limited access to accurate information on which to base their decisions. “Northern” conceptualizations of self, human origins, risks and potential benefits have shaped approaches to consent, specimen collection, ownership and information sharing — approaches that may be at odds with local meaning-making and therefore of limited value in determining what constitutes ethical practice in these communities .
Recent work by Staunton and Moodley identified five studies in the literature that have examined community perspectives on the storage and reuse of biospecimens in countries in Sub-Saharan Africa . Less research has been done to date to gauge the knowledge and perspectives of local ethics committee members who have an essential role to play in protecting stakeholder interests. IRB members may require more information about the science and ethical use of biospecimens in research as well as better policy guidance at a national level if they are to strike the right balance between ensuring safeguards for subjects and their communities on the one hand and facilitating research with potential public health benefits on the other. As efforts to establish biobanks across the African continent expand, due consideration must be given to the extent to which ethics committees have the knowledge to serve as ethical gatekeepers, particularly in communities where local understanding of biomedicine may be rudimentary or at odds with cultural meanings traditionally ascribed to biological phenomena.
Botswana has attracted global attention over the past three decades as a hub for behavioral, epidemiological, and clinical research. A number of foreign academic research universities and NGOs have established study centers in Botswana, including Baylor International Pediatric AIDS, Botswana Harvard AIDS Institute Partnership, otswana-UPenn Partnership, BOTUSA Project, and I-TECH Botswana [14–18]. The University of Botswana opened the country’s first medical school and school of public health in 2009 and has a commitment to advance research and graduate studies as part of its current strategic plan . A number of studies examining genetic attributes of particular sub-populations in Botswana have already begun [20, 21] and the creation of a biorepository at the University of Botswana with the eventual public release of data for future research activities is planned as part of the H3Africa initiative .
The Botswana Anthropological Research Act of 1967 provides the basis for research regulation . In 1984, a Health Research Unit (HRU) was created within the Ministry of Health (MoH) and a Health Research and Development Committee (HRDC) established to review, approve, and oversee all health-related research. An Institutional Review Board (IRB) has been in operation at the University of Botswana since 2004; it is responsible for the review and approval of all undergraduate and masters-level research permits and intramural faculty research. It is also tasked with the preliminary review and referral of all health-related PhD and international research to the HRDC for final approval. IRBs have also been in operation for some time at large referral hospitals in Gaborone, Francistown, and Maun. In 2010, the MoH launched a multi-year endeavor to create a country-wide system of local ethics committees to meet the growing demand for ethics review and the expansion of research activities to small communities outside the capital city. Frameworks now exist in a number of the district hospitals for ‘local’ IRBs to provide feedback to the HRDC on the feasibility of projects proposed for their facilities, although most lack infrastructure and research expertise (Kasule M 2014, personal communication). New ethics committees have also been established in various tertiary academic institutions throughout the country, but these are limited in their scope of authority to the review of research proposals by students at the masters level and below. Reviews conducted by this emergent ‘system’ of IRBs are submitted as recommendations to the HRDC, which operates as the national review body for Botswana and remains responsible for final review and monitoring of all health research in the country.
The HRDC is guided by principles articulated in the Declaration of Helsinki, and the Council for International Organizations of Medical Sciences’ International Ethical Guidelines for Biomedical Research involving Human Subjects [24, 25]. Until recently, regulatory guidance on HBS existed only for clinical trials relating to drug applications . In 2011, the Ministry of Health issued Standard Operating Procedures intended to guide the structure and operation of the HRDC and the review of research protocols involving human subjects . A National Health Research Bill remains under review at the parliamentary level.
To date, ethics training programs for IRB members in Botswana have focused on ethical principles and international guidelines rather than on ethical dimensions of specific medical technologies and research methodologies. Little is known about the knowledge, concerns, and training needs of IRB members in Botswana with respect to the use of biospecimens in biomedical research.
Members of the HRDC and all IRBs in Botswana at the time of the study were invited by letter with follow-up phone and email reminders to participate in one of several focus groups to be held at various locations in Botswana in March 2013. A total of 41 IRB members drawn from five different committees participated, a sample representing a majority of those members serving on committees tasked with review of protocols involving HBS. Sessions were designed to elicit IRB-member perceptions of common attitudes and beliefs of Batswana (the people of Botswana) towards the collection and use of HBS for research and to gauge member knowledge and attitudes about these issues. Additionally, the research team was interested in IRB-member awareness of existing national regulation regarding the collection and use of HBS, their confidence in its adequacy to guide review, and their perceived need for additional training.
Focus groups took place in Gaborone (two groups of 17 and six participants, respectively) and Francistown (one group of 10 participants), both urban centers in which biomedical research activity has to date been concentrated. One discussion group (eight participants) took place in Mahalapye, a major town to the northeast of Gaborone where the new District Hospital has recently appointed its first IRB. Approximately 70 % of the participants were female. All had received some training in research ethics, but none had received training specific to biospecimens, genetic or genome-based research, or bio-repositories. A number of the members from the HRDC and the University of Botswana were researchers and health professionals familiar with biomedical science. The remaining three committees represented were relatively new, tasked with ‘local’ review of protocols that will be situated in their hospitals and with evaluating their suitability given hospital capacity and local cultural norms and practices. Members of these committees tend to have received less training in ethics compared to their urban counterparts and are less familiar with health research in general. Ethical issues concerning the collection and use of HBS has not been a topic of focus in ethics training programs to date.
Each focus group discussion was guided by a study script. Study questions were chosen with the intention to stimulate a free-flowing conversation in English (the official language of Botswana) to explore IRB members’ own views on the collection and use of biospecimens, as well as what they perceived to be the views of local communities.
From your perspective, how do the peoples of Botswana feel about the collection of biospecimens?
From your perspective, how do the peoples of Botswana feel about biospecimens being kept or stored after the original research has been completed?
As an IRB reviewer or someone interested in ethics, what are your greatest concerns about the storage and reuse of biospecimens?
Should there be any constraints or conditions placed on the future use of stored biospecimens after the original research is over?
An informal training session about genetic and genomic research was offered at the end of each discussion group. These sessions, intended as a capacity-building effort, were not audiotaped nor were discussions that took place during them considered study data.
The project was reviewed and approved prior to its implementation by the Institutional Review Boards at Rutgers University, the University of Botswana and the University of Pennsylvania, as well as the Health Research and Development Committee at the Botswana Ministry of Health.
For the purposes of the study, a number of words whose conceptual meanings did not directly translate into English were left in Setswana, the recognized local language of Botswana. Batswana is the collective noun used to describe the people of Botswana. Go rupa and bogwera, once terms in Setswana (the local language of Botswana) used to describe traditional initiation ceremonies for adolescent boys, is now used by the Botswana MoH to refer to medical male circumcision. Muti is the Setswana term used to refer to objects of witchcraft. In describing the ethics system in Botswana, the study used terms commonly used in that country. Ethics research committees in Botswana are referred to as ‘IRBs’ and its members as ‘IRB members’. The IRB at the Ministry of Health is called the Health Research and Development Committee (HRDC).
Cultural traditions, norms and beliefs
“When [the campaign] started, [health workers] took their foreskins and just threw them away. Local people were concerned because this is not a tissue. This has meaning. There was a rumor that the foreskins were being sold to traditional doctors. They started thinking that maybe this circumcision is not what they thought it would be.”
Study participants also observed many Batswana are concerned that foreskins removed as part of this campaign are being sold for other people’s use. Many people, particularly those with less education and those from remote areas of the country, still believe in witchcraft and fear that body parts, including blood and samples that are collected by health workers, will be stolen or sold to make powerful magic (muti) that can harm or bring benefit to others.
“Why should I allow a medical person to collect a sample from me? If I am sick, for example, if I have cancer; God has his way of healing cancer. Why would I just allow a person who gets his wisdom from God to go and test it? Nature will take its course; it will heal in time if one believes in God.”
“If these [stored] specimens are out there somewhere in the developed world – far out there- just as I am about to die, can these specimens come back because I want to go to my grave whole? Not to leave part of it over there, overseas? How do these specimens come back? I will not have a peaceful death because I am worried that I am facing death without all my specimens. A breast is somewhere.”
Lack of trust
“If you are a foreign team coming from outside and going to the rural areas, there may be suspicion. Even if you are from Botswana and you come with a team – let’s say you are coming from Gaborone to a rural area- they will always suspect that you are going to take something and that you are doing it for something. But if you were from a foreign country, I think it will be even worse.”
“I think that [early on] they saw the [actual] process of circumcision as a medical component – as separate from the rest of the circumcision initiation. They never asked what we were going to do. I think they were confident that we were doing exactly what we said we were going to do… Since research arrived in the country, most people are wary of research, suddenly these issues take on a different complexion. These tests are often not used for the person’s own care. So they don’t know who will see the results or how [specimens] will be used.”
Misunderstanding of the role of biospecimens in clinical and research settings
“You know, most Batswana, they expect to get results after you’ve collected a specimen, But now with research, if you take a specimen, you are not going to give any results. Is that right? [Researchers] go to families and collect blood specimens. And the results are not revealed to the people. They were advised to go to the hospital to get tested to know their HIV status. So you know from their perspective, they feel cheated. They sometimes feel cheated when it is put that way.”
Some patients believe that the collection of certain types of specimens, especially spinal fluid, actually worsens health and may hasten death in sick patients. Spinal taps, invariably performed in very sick patients, were reported to be broadly perceived as deadly. In instances of amputation or extraction, it was not uncommon for patients to ask that the limb or tooth be returned to them for ritual disposal.
“I think mostly they don’t know that they are being kept. If they knew…they will think that persons are using their specimens to do something else which they didn’t agree to. Mostly they don’t know. They think that their specimen was taken and was used.”
Reuse of biospecimens
“If they are going to take research samples and store them for a long time and then use them for studies that are not disclosed to the individuals, then those persons do not have autonomy over what is going to be don. The researcher needs to at least say something like ‘I am going to use this in the future for HIV research’, and then if the researcher were to [want to] use it for some other purposes, it would not be permitted without permission… I do not think there should be blanket consent, particularly for research that relates specifically to them [the participants].”
Consent for each new use was the predominant preference among discussants, although there were mixed opinions about the source and nature of such consent. A number of IRB members felt that even when research subjects could give meaningful consent to reuse at the time of collection, requests for reuse should still be reviewed and approved by an IRB or another ‘local group’. Some participants felt that donors should be contacted and new consents obtained for each use, while others were comfortable with review and approvals for future uses by an individual assigned responsibility for the management and supervision of the specimen storage facility. One group agreed that an IRB could approve future uses but emphasized that the reviewing IRB should be a national body, such as the HRDC, and not a local IRB like itself. Those that felt that authority for approval of future use could be delegated to an IRB or other body also felt it was imperative that a strong national regulatory framework be in place so that ‘rules were established and clear’.
IRB members who felt that all reuse was contingent on re-consent by individuals and families from whom the specimens had been obtained stated that specimens needed to be kept in identifiable form for this purpose. Somewhat at odds with this point of view, they were also part of a majority of participants who expressed the view that it was important that specimens be stored in de-identified form for all reuse as a way to ensure privacy. At the same time, most felt that it was important to be able to link data back in the event of discoveries that might be relevant to their health.
There was a fairly lengthy discussion in all groups about the criteria for reuse. Several participants voiced the opinion that many Batswana would be opposed to reuse if the intended uses were not specified. It was felt that researchers would be seen to be “conniving” if they request permission to re-use specimens for unspecified purposes. Those who thought reuse might be acceptable to research subjects shared a number of different viewpoints about the conditions that would apply, including reuse only within the context of the original study, reuse for future studies within the same disease category, reuse during a fixed period of time, and reuse contingent on approval of donors and/or an IRB.
“It should not just be a blanket, open reuse…I shouldn’t [get] to reuse specimens just because today I feel like doing research on something that doesn’t return to the nation or to the community. You shouldn’t just be doing research because you just want to learn whatever is happening. There are national and community interests.”
Ownership and storage
“If I donate a sample for research as a participant, that sample is mine. That belongs to me…My DNA and everything is there. That belongs to me… I need some control or comfort level with my sample.”
“I think that if I get specimens for my research, there should be a point at which they don’t belong to me anymore, when they ought to belong to the community of researchers or to the human community. [But] there should also be regulations at different levels. You know, if the specimens are here at some stage, they have to be transferred from me either to the university or to the country and the country will take custody of those specimens for future generations and everybody else.”
The common belief that specimens are “used up” in an individual’s care was seen by most IRB members as a major obstacle to acceptance by Batswana of HBS reuse and storage. One discussant observed “the keeping is the problem,” conveying in one phrase local concerns that specimens would not be wholly used for a person’s own care, that specimens would be “out there somewhere” at the time of death, and that someone else without the same obligations to self, community, and country would control them.
“My concern is the fact that once specimens have been collected, at some point, people [will be] required to destroy them. It’s such a waste, you know…. To say after three years, ‘okay, destroy them’ doesn’t seem to me to be a good solution. It presumes that we are going to do harm with that specimen [and that] we [the IRB] are not watching. We just throw away specimens. One hundred years from now, researchers would benefit from specimens if they can keep them that long. But unfortunately we throw them away.”
IRB-member attitudes towards storage were linked to concerns about access. Many felt that storage of specimens could be of benefit if priority access was given to local researchers wishing to conduct research of direct benefit to Botswana. There was general agreement that a regulatory framework was needed to ensure safeguarding of specimens regardless of duration of storage.
“I have a problem with the specimens going out. Why? Because you never know what they are going to be used for. You have no control over them once they have left the country. I’d rather prefer whoever wants to do that research should have a budget that is enough to bring whatever equipment or facility here and do whatever he wants to do in the country so we can benefit.”
Participants acknowledged the need to build capacity in-country for storage, safekeeping, and research, with most voicing the view that the international research community should help in this effort.
Potential benefits and benefit-sharing
Concerns about reuse and storage were generally linked to considerations about how individuals, communities, and the nation could benefit. Complicating such discussions was the conflation of ‘payment’ to research subjects for their time and inconvenience at point of specimen collection with ‘benefit’. Because many IRB members viewed this practice as payment to subjects for the use of their sample or information, it followed that subjects should continue to be paid (in their words ‘benefit’) each time their samples were re-used.
IRB members felt it was important that any benefits derived from the use of stored specimens, including monetary gains, intellectual property rights, or new treatments, should be shared with the individuals who provided the specimen, their communities, and/or the nation as a whole. Most participants recognized that this is already a concern with current single-study use that would become more pronounced when specimens were stored and reused, particularly if storage was located outside of Botswana.
“If they [research subjects] are not given results, it affects the future and the chances that others will give specimens. How come you always come to us and never give us feedback?”
“We see nowadays people who have contributed to the good work, contributed to the research in many ways….how do we recognize [and] reward the person, from whose specimens we learned something important?....Reward does not need to be monetary… If the people contributed to an achievement in research, they should be recognized and acknowledged. If our grandfathers built a school, we continue to be proud of this school because it wears our grandfathers’ names.”
Educational needs and regulatory guidance
“The official training would help. It would be better than what we are now. We don’t want to be biased. If we tell someone that they have to comply, we need to know… For some [IRB members] its core business, but the rest of us are dragged in. If you knew this was ‘certified’ business, you would work more at it.”
“We came here to do other things; we are [co-] opted to be in the IRB. I don’t even have time to think or read on my own, or to learn what the expectations are. And I have to read so many papers.”
When asked if they were familiar with any regulatory guidance for research and if so, if they felt it was adequate, most study participants agreed that such guidance existed, but were generally not familiar with it or felt that it was ‘easy to bypass’. All but one IRB member believed that there were existing regulations about biospecimens. Most participants were familiar with the existence of a forthcoming Health Research Law and expressed general anticipation that this law would address existing inconsistencies and concerns with respect to access, ownership, and storage of biospecimens and benefit-sharing.
“[A national policy] would be very important. See, right now, either we don’t know things well, or we can bypass them. If there were clear regulations, we would be able to prevent people from operating differently. Tomorrow I am going to be able to say, ‘This is the law’. A proper legislation, along with penalties and everything. It will apply to everybody. That would be better.”
A number of the issues raised by study participants echo findings from other studies in developing countries that examined community attitudes and norms towards biomedical research. Similar concerns about the use of human ‘parts’ for sorcery or witchcraft have previously been reported in the academic literature as has the attribution of cultural meaning to parts of the human body [29–33].
Bodily integrity, particularly at death, has been identified as a critical value in various cultural and religious traditions and one with significant ramifications for research [34, 35]. To what extent the meaning given to bodily integrity might cause communities to resist the donation of biospecimens for future research and storage is new to considerations about biobanking in Africa and warrants further study, particularly in the context of genetic and genomic research involving biosamples in Botswana.
Trust has also been identified elsewhere as central to the research subject–researcher relationship and in the willingness of individuals to participate in research [31, 32, 36, 37]. IRB members in Botswana emphasized the absence of trust as a significant problem, attributing this in part to lack of understanding on the part of Batswana and lack of adequate explanation and study feedback on the part of researchers. This failure to engage with communities adequately has been cited previously as a cause for erosion of trust in researchers in developing countries . De Vries and colleagues observed that trust between researchers and research subjects may be further diluted when samples are exported for use by strangers in foreign countries .
IRB-member views that Batswana are likely to be resistant to the reuse of their specimens is in sharp contrast with earlier findings from Uganda that 95 % of research subjects interviewed would be comfortable with the reuse of their biospecimens contingent on IRB review . A recent study by Igbe and Adebamowo also found that lay persons in Nigeria, once biobanking was explained to them, felt that storage and reuse was a ‘worthwhile’ activity .
Donor consent or local approval for reuse was preferred by the majority of IRB members in this study, a point of view they felt accurately represented how Batswana in general would feel and how they themselves felt as members of the IRB. Most agreed that review and decision-making could be delegated to a knowledgeable IRB or other regulatory body in Botswana. Review and approval by bodies outside the country was generally not considered adequate protection for the interests of the individuals and communities from whom the biospecimens had been collected.
Ownership was a particularly contentious topic in this study, reflecting a consensus that samples ultimately belonged to the people of Botswana and by extension should be under the care and protection of the national government. Similarly, Moodley and colleagues found that most of the perspectives voiced by research subjects in South Africa regarding sample storage, export, reuse, and benefit-sharing ultimately had to do with ownership . Participants in that study, despite discussions about ‘donations’, persisted in referring to ‘my blood’ or ‘my child’s blood’ just as IRB members in this study repeatedly emphasized “my specimen”, “my samples”, or commented “if I donate a sample for research as a participant, that sample is mine”.
The expectation that an individual’s samples will be used up in the course of his or her own care may be viewed by Batswana as a fair exchange — the ‘giving up’ of a specimen in exchange for treatment or return to health — that is absent when they are asked to provide a specimen for the purposes of research. Certainly there is concern among IRB members that societal benefits may be absent if specimens are taken outside the country or if decisions as to their future use do not remain in the hands of the donors themselves or the government of Botswana. IRB members in Botswana discussed benefits both in very basic terms of compensation to research subjects themselves and in broader language suggesting that they view biosamples as a collective resource that should be used primarily for the benefit of the country and all its citizens.
Familiarity with pharmacogenetics and genomic research was limited in IRB members participating in this study. Participants on the two most active IRBs – the national HRDC and the IRB at the University of Botswana – were more comfortable discussing the scientific aspects of research and more likely to consider the potential benefits of genetic- and genomic-based research than their counterparts in the newer and less active IRBs. There was a uniform call from all IRB members for more training in these areas, a need that has been expressed by similar constituencies in other African countries [41–44].
Uniformly absent from the discussions in all groups, regardless of their familiarity with research or their experience as IRB members, were several topics of particular relevance to biomedical research in Botswana. First, the concept of ‘benefit’ was narrowly viewed by IRB members only within the context of individual, community, and national interests of Botswana. Little, if any, consideration was given to the potential benefits that genetic- and genomic-based research using biospecimens from Botswana could offer other peoples in Africa or other populations worldwide sharing common traits, risk-profiles or diseases despite follow-on questions on this issue from the study team. This consideration of benefit only within the geographic boundaries of their country may simply reflect what IRB member participants perceived as the ‘local’ focus of this current study. However, if the discussants’ comments are symptomatic of a broader territorial protectionism, it suggests that there may be some resistance to proposals that call for export of biospecimens to regional or non-African biorepositories located outside of Botswana. Concerns such as these, for example, have been noted previously in South Africa . In particular, it may reflect a negative view of management and reuse of such specimens by foreign investigators without local oversight. Such attitudes could be directly at odds with the ‘common heritage’ approach that underpins many international and regional strategies for biobanking, including the current H3Africa initiatives [7, 46].
Second, despite the near unanimity of IRB members as to the lack of understanding on the part of research subjects in Botswana and the particularly disturbing reports that participants are frequently unaware that they are subjects of research or that their specimens are not exhausted in their own care, the IRB members participating in this study did not evidence any sense of personal responsibility as ‘gatekeepers’ to address such concerns. Despite the national mandate to its IRBs to “ensure that the dignity, rights, safety and well-being of research subjects are protected” , and the IRB members’ uniform call for more ethics training, there was little evidence that the IRB members at present saw their boards accountable for the remediation of ethical ‘gaps’ in how studies are actually taking place on the ground. Training requirements for new IRB members, combined with continuing professional development opportunities for current members, can certainly help. The success of such efforts, however, will depend on the existence of clear regulatory guidance as well as adequate investment in research governance and support structures. All IRB members need to be given access to training, time-off from other responsibilities, and recognition for the value of their service if they are to function as effective, meaningful stewards of citizen safety, rights, and dignity in research.
Limitations of this study
The authors chose to study the perspectives of IRB members in Botswana in order to understand the challenges they face as ethical gatekeepers responsible for the review of increasingly sophisticated research involving the collection, use, and storage of HBS, and to assess the need from by IRB members for specialized training in this domain. To that end, the study provides insights through their eyes only on community knowledge, attitudes, and beliefs about biospecimens. To address this limitation, more studies are needed in Botswana that directly engage local communities in order to appreciate what is likely to be the broad range of understanding and opinion on ethical, legal, and social implications associated with biospecimens, particularly those collected as part of research biorepositories. The need for such discussions have been recently highlighted by the H3Africa Working Group on Ethics . At the same time, opportunities for more in-depth debate among IRB members in Botswana regarding areas of concern to the constituencies they protect would help to tailor both future IRB-member training and public health outreach. Information provided through studies involving other non-Botswana populations as well as international guidance on ethical concerns at the community-level in developing countries offer some help in navigating the terrain but are not sufficient to fully understand local complexities nor identify points of opportunity for education, participation, and collaboration that are most appropriate for Botswana.
This study also identified some areas that may prove less malleable to change. These include indigenous meanings ascribed to the human body and its parts that seem to be at odds with ‘western’ scientific knowledge and practice. Engagement by the international research community with local stakeholders will be needed to harmonize these fundamentally different ways of understanding the human body and community identity with the aims of contemporary biomedicine.
