1.  Reaching the hard to reach: longitudinal investigation of adolescents’ attendance at an after-school sexual and reproductive health programme in Western Cape, South Africa 
BMC Public Health  2015;15:608.
Adolescents need access to effective sexual and reproductive health (SRH) interventions, but face barriers accessing them through traditional health systems. School-based approaches might provide accessible, complementary strategies. We investigated whether a 21-session after-school SRH education programme and school health service attracted adolescents most at risk for adverse SRH outcomes and explored motivators for and barriers to attendance.
Grade 8 adolescents (average age 13 years) from 20 schools in the intervention arm of an HIV prevention cluster randomised controlled trial in the Western Cape Province of South Africa, were invited to participate in an after-school SRH program and to attend school health services. Using a longitudinal design, we surveyed participants at baseline, measured their attendance at weekly after-school sessions for 6 months and surveyed them post-intervention. We examined factors associated with attendance using bivariate and multiple logistic and Poisson regression analyses, and through thematic analysis of qualitative data.
The intervention was fully implemented in 18 schools with 1576 trial participants. The mean attendance of the 21-session SRH programme was 8.8 sessions (S.D. 7.5) among girls and 6.9 (S.D. 7.2) among boys. School health services were visited by 17.3 % (14.9 % of boys and 18.7 % of girls). Adolescents who had their sexual debut before baseline had a lower rate of session attendance compared with those who had not (6.3 vs 8.5, p < .001). Those who had been victims of sexual violence or intimate partner violence (IPV), and who had perpetrated IPV also had lower rates of attendance. Participants were motivated by a wish to receive new knowledge, life coaching and positive attitudes towards the intervention. The unavailability of safe transport and domestic responsibilities were the most common barriers to attendance. Only two participants cited negative attitudes about the intervention as the reason they did not attend.
Reducing structural barriers to attendance, after-school interventions are likely to reach adolescents with proven-effective SRH interventions. However, special attention is required to reach vulnerable adolescents, through offering different delivery modalities, improving the school climate, and providing support for adolescents with mental health problems and neurodevelopmental academic problems.

2.  Intimate Partner Violence among Adolescents in Cape Town, South Africa 
To describe potentially preventable factors in intimate partner violence (IPV) perpetration and victimization among South African 8th grade students.
Data were collected during a pilot evaluation of a classroom 8th grade curriculum on gender-based violence prevention in 9 public schools in Cape Town through self-completed interviews with 549 8th grade students, 238 boys and 311 girls. Structural equation models (SEM) predicting IPV were constructed with variables a priori hypothesized to be associated.
The majority of students (78.5%) had had a partner in the past three months, and they reported high rates of IPV during that period (e.g., over 10% of boys reported forcing a partner to have sex, and 39% of girls reported physical IPV victimization). A trimmed version of the hypothesized SEM (CFI =.966; RMSEA=.051) indicated that disagreement with the ideology of male superiority and violence predicted lower risk of IPV (p<.001), whereas the frequency of using negative conflict resolution styles (e.g., walking off angrily, sending angry text messages, or refusing to talk to them) predicted high IPV risk (p<.001) and mediated the impact of heavy alcohol drinking on IPV (Sobel test, z=3.16; p<.001). The model fit both girls and boys, but heavy drinking influenced negative styles of resolving conflict more strongly among girls than boys.
Findings suggest that interventions to reduce IPV among South African adolescents should challenge attitudes supportive of male superiority and violence; encourage use of positive conflict resolution styles; and discourage heavy alcohol use among both boys and girls.

3.  Patient Experiences following Acute HIV Infection Diagnosis and Counseling in South Africa 
PLoS ONE  2014;9(8):e105459.
Individuals in the acute stage of HIV infection (AHI) have an elevated potential to transmit HIV and play a critical role in the growth of the epidemic. Routine identification and counseling of individuals during AHI could decrease transmission behavior during this key period. However, diagnosis of AHI may present challenges distinct from those experienced through diagnosis of established HIV infection. A study was conducted in a public youth clinic outside of Cape Town, South Africa, to identify and counsel individuals with acute stage HIV infection. In-depth interviews were conducted with patients following diagnosis. After counseling, patients were accepting of the testing regimen used to diagnose AHI. They used the knowledge of having been recently infected to identify the source of their infection, but did not retain or place importance on information regarding the increased ability to transmit HIV during the acute stage. Future interventions directed at the reduction of HIV transmission following diagnosis with AHI will need to find ways of making this information more salient, possibly through more culturally meaningful educational approaches.

4.  A comparison of linkage to HIV care after provider-initiated HIV testing and counselling (PITC) versus voluntary HIV counselling and testing (VCT) for patients with sexually transmitted infections in Cape Town, South Africa 
We examined linkage to care for patients with sexually transmitted infection who were diagnosed HIV-positive via the provider-initiated HIV testing and counselling (PITC) approach, as compared to the voluntary counselling and testing (VCT) approach, as little is known about the impact of expanded testing strategies on linkage to care.
In a controlled trial on PITC (Cape Town, 2007), we compared HIV follow-up care for a nested cohort of 930 HIV-positive patients. We cross-referenced HIV testing and laboratory records to determine access to CD4 and viral load testing as primary outcomes. Secondary outcomes were HIV immune status and time taken to be linked to HIV care. Logistic regression was performed to analyse the difference between arms.
There was no difference in the main outcomes of patients with a record of CD4 testing (69.9% in the intervention, 65.2% in control sites, OR 0.82 (CI: 0.44-1.51; p = 0.526) and viral load testing (14.9% intervention versus 10.9% control arm; OR 0.69 (CI: 0.42-1.12; p = 0.131). In the intervention arm, ART-eligible patients (based on low CD4 test result), accessed viral load testing approximately 2.5 months sooner than those in the control arm (214 days vs. 288 days, HR: 0.417, 95% CI: 0.221-0.784; p = 0.007).
The PITC intervention did not improve linkage to CD4 testing, but shortened the time to viral load testing for ART-eligible patients. Major gaps found in follow-up care across both arms, indicate the need for more effective linkage-to-HIV care strategies.

5.  Alcohol and Other Drug Use during Pregnancy among Women Attending Midwife Obstetric Units in the Cape Metropole, South Africa 
Little is known about the nature and extent of alcohol and other drug (AOD) use among pregnant women in Cape Town, South Africa, despite the very high levels of AOD use in this part of the country. A cross-sectional survey was conducted among pregnant women attending 11 Midwife Obstetric Units (MOUs) in greater Cape Town. A two-stage cluster survey design was used. In total, 5231 pregnant women were screened to assess self-reported prevalence estimates. Of these, 684 (13.1%) were intentionally subsampled and completed an interviewer-administered questionnaire and provided a urine sample for biological screening. Urinalyses showed that 8.8% (95% CI: 6.7–10.9) of the subsample tested positive for at least one illicit drug. This is higher than the self-reported prevalence (3.6%). In addition, 19.6% (95% CI: 16.3–22.8) of the sub-sample tested positive for alcohol which is lower than the self-reported prevalence (36.9%). There are high levels of substance use among pregnant women attending public sector antenatal clinics. There is a need for routine screening for AOD use and appropriate responses depending on the women's level of risk.

6.  Promoting sexual and reproductive health among adolescents in southern and eastern Africa (PREPARE): project design and conceptual framework 
BMC Public Health  2014;14:54.
Young people in sub-Saharan Africa are affected by the HIV pandemic to a greater extent than young people elsewhere and effective HIV-preventive intervention programmes are urgently needed. The present article presents the rationale behind an EU-funded research project (PREPARE) examining effects of community-based (school delivered) interventions conducted in four sites in sub-Saharan Africa. One intervention focuses on changing beliefs and cognitions related to sexual practices (Mankweng, Limpopo, South Africa). Another promotes improved parent-offspring communication on sexuality (Kampala, Uganda). Two further interventions are more comprehensive aiming to promote healthy sexual practices. One of these (Western Cape, South Africa) also aims to reduce intimate partner violence while the other (Dar es Salaam, Tanzania) utilises school-based peer education.
A modified Intervention Mapping approach is used to develop all programmes. Cluster randomised controlled trials of programmes delivered to school students aged 12–14 will be conducted in each study site. Schools will be randomly allocated (after matching or stratification) to intervention and delayed intervention arms. Baseline surveys at each site are followed by interventions and then by one (Kampala and Limpopo) or two (Western Cape and Dar es Salaam) post-intervention data collections. Questionnaires include questions common for all sites and are partly based on a set of social cognition models previously applied to the study of HIV-preventive behaviours. Data from all sites will be merged in order to compare prevalence and associations across sites on core variables. Power is set to .80 or higher and significance level to .05 or lower in order to detect intervention effects. Intraclass correlations will be estimated from previous surveys carried out at each site.
We expect PREPARE interventions to have an impact on hypothesized determinants of risky sexual behaviour and in Western Cape and Dar es Salaam to change sexual practices. Results from PREPARE will (i) identify modifiable cognitions and social processes related to risky sexual behaviour and (ii) identify promising intervention approaches among young adolescents in sub-Saharan cultures and contexts.

7.  Linkage to HIV Care from a Mobile Testing Unit in South Africa by Different CD4 Count Strata 
The linkage and barriers of linkage to facility-based HIV care from a mobile HIV testing unit have not previously been described.
A stratified random sample (N=192) was drawn of all eligible, newly-diagnosed HIV-infected individuals with a laboratory CD4 count result on a mobile unit between August 2008 and December 2009. All individuals with CD4 counts ≤ 350 cells/μl and 30% of individuals with CD4 counts > 350 cells/μl were sampled. Linkage to care was assessed during April to June 2010 in those that received their CD4 count result. A participant who accessed HIV care at least once after testing was regarded as having linked to care. Binomial regression models were used to identify clinical and socio-demographic factors associated with receiving a CD4 count result and linking to care.
Forty-three (27%) individuals did not receive their CD4 count result. A lower CD4 count, being female and the availability of a phone number increased the likelihood of receiving this result. Follow-up was attempted in the remaining 145 individuals. Ten refused to participate and contact was unsuccessful in 42.4%. Linkage was 100% in patients with CD4 counts ≤ 200 cells/μl, 66.7% in individuals with CD4 counts of 201-350 cells/μl and 36.4% in those with CD4 counts > 350 cells/μl. A lower CD4 count, disclosure, presence of TB symptoms and unemployment increased the likelihood of linking to care.
Linkage to care was best among those eligible for ART. Interventions designed at improving linkage among employed individuals are urgently warranted.

8.  Condom use and sexuality communication with adults: a study among high school students in South Africa and Tanzania 
BMC Public Health  2013;13:874.
Fostering adolescents’ communication on sexuality issues with their parents and other significant adults is often assumed to be an important component of intervention programmes aimed at promoting healthy adolescent sexual practices. However, there are few studies describing the relationship between such communication and sexual practices, particularly in sub-Saharan Africa. This study examined the relationships between adolescents’ communication with significant adults and their condom use in three sites in this region.
Data stem from a multi-site randomized controlled trial of a school-based HIV prevention intervention implemented in Cape Town and Mankweng, South Africa and Dar es Salaam, Tanzania. Only data from comparison schools were used. The design is therefore a prospective panel study with three waves of data collections. Data were collected in 2004 from 6,251 participants in 40 schools. Associations between adolescents’ communication with adults about sexuality issues and their use of condoms were analysed cross-sectionally using analysis of variance, as well as prospectively using multiple ordinal logistic regression analysis.
Cross-sectional analyses showed that consistent condom users had significantly higher mean scores on communication (across topics and communication partners) than both occasional users and never-users, who had the lowest scores. After controlling for condom use at the first data collection occasion in each model as well as for possible confounders, communication scores significantly predicted consistent condom use prospectively in all three ordinal logistic regression models (Model R2 = .23 to .31).
The findings are consistent with the assertion that communication on sexuality issues between adolescents and significant adults results in safer sexual practices, as reflected by condom use, among in-school adolescents. The associations between communication variables and condom use might have been stronger if we had measured additional aspects of communication such as whether or not it was initiated by the adolescents themselves, the quality of advice provided by adults, and if it took place in a context of positive adult-adolescent interaction. Studies with experimental designs are needed in order to provide stronger evidence of causality.

9.  Implementing a provider-initiated testing and counselling (PITC) intervention in Cape town, South Africa: a process evaluation using the normalisation process model 
Provider-initiated HIV testing and counselling (PITC) increases HIV testing rates in most settings, but its effect on testing rates varies considerably. This paper reports the findings of a process evaluation of a controlled trial of PITC for people with sexually transmitted infections (STI) attending publicly funded clinics in a low-resource setting in South Africa, where the trial results were lower than anticipated compared to the standard Voluntary Counselling and Testing (VCT) approach.
This longitudinal study used a variety of qualitative methods, including participant observation of project implementation processes, staff focus groups, patient interviews, and observation of clinical practice. Data were content analysed by identifying the main influences shaping the implementation process. The Normalisation Process Model (NPM) was used as a theoretical framework to analyse implementation processes and explain the trial outcomes.
The new PITC intervention became embedded in practice (normalised) during a two-year period (2006 to 2007). Factors that promoted the normalising include strong senior leadership, implementation support, appropriate accountability mechanisms, an intervention design that was responsive to service needs and congruent with professional practice, positive staff and patient perceptions, and a responsive organisational context. Nevertheless, nurses struggled to deploy the intervention efficiently, mainly because of poor sequencing and integration of HIV and STI tasks, a focus on HIV education, tension with a patient-centred communication style, and inadequate training on dealing with the operational challenges. This resulted in longer consultation times, which may account for the low test coverage outcome.
Leadership and implementation support, congruent intervention design, and a responsive organisational context strengthened implementation. Poor compatibility with nurse skills on the level of the clinical consultation may have contributed to limiting the size of the trial outcomes. A close fit between the PITC intervention design and clinical practices, as well as appropriate training, are needed to ensure sustainability of the programme. The use of a theory-driven analysis promotes transferability of the results, and the findings are therefore relevant to the implementation of HIV testing and to the design and evaluation of complex interventions in other settings.

10.  Sexual health, HIV risk, and retention in an adolescent HIV prevention trial preparatory cohort 
Adolescents are at high risk for HIV infection, yet have not been included in HIV vaccine trials.
In preparation for their enrollment in HIV vaccine trials, 100 HIV-negative 14 to 17 year olds from Cape Town were recruited into a cohort. HIV, syphilis, pregnancy testing, and sexual risk questionnaires were performed at varying intervals for one year.
The mean age of the participants was 15 years, and 70% were female. Recruitment was completed in three months. Retention was 82% at 1 year. The main reasons for dropout were relocation to other communities, phlebotomy, and visit frequency. In a Cox proportional hazards model, only female gender was significantly associated with retention. No change in reported sexual risk occurred, but the proportion knowing their partners’ HIV status was significantly higher (17% at baseline, 83% at one year; p<0.001). There were five pregnancies during follow-up.
To our knowledge, this is the first prospective adolescent HIV prevention cohort in Southern Africa. Despite reports of risky sex and high pregnancy rates, HIV seroconversions did not occur in the retained cohort. HIV prevention trials with high-risk adolescents will require rigorous efforts to prevent pregnancy, and may require risk eligibility criteria. Retention may improve with transport provision, incentivizing visits, and efforts to retain males.

11.  Predicting substance use behavior among South African adolescents: The role of leisure experiences across time 
Using seven waves of data, collected twice a year from the 8th through the 11th grades in a low-resource community in Cape Town, South Africa, we aimed to describe the developmental trends in three specific leisure experiences (leisure boredom, new leisure interests, and healthy leisure) and substance use (cigarettes, alcohol, and marijuana) behaviors and to investigate the ways in which changes in leisure experiences predict changes in substance use behaviors over time. Results indicated that adolescents’ substance use increased significantly across adolescence, but that leisure experiences remained fairly stable over time. We also found that adolescent leisure experiences predicted baseline substance use and that changes in leisure experiences predicted changes in substance use behaviors over time, with leisure boredom emerging as the most consistent and strongest predictor of alcohol, cigarette, and marijuana use. Implications for interventions that target time use and leisure experiences are discussed.

12.  Changes to the law on consent in South Africa: implications for school-based adolescent sexual and reproductive health research 
The National Health Act, No 61, 2003 in South Africa is the first effort made by the government to protect health-related research participants under law. Implemented on March 1, 2012, the law mandates active consent from a parent or legal guardian for all research conducted with research participants under the age of 18 years. This paper focuses on the Act's implications for school-based adolescent sexual and reproductive health research.
Although well intentioned, the added legal protections in the National Health Act may have the unintended consequence of reducing participation rates in school-based adolescent sexual and reproductive health research, thereby excluding the most at-risk students. The Act may also compromise adolescents' right to dignity and privacy, especially considering the personal nature of research on sex and sexuality. Devolved, discretionary decision-making, which empowers local human research ethics committees to permit a wider range of protective measures, including passive consent, independent adolescent consent or community consultation ought to be considered. The continued and direct involvement of young people in their sexual and reproductive health and well-being is an important principle to uphold.
This paper calls for a re-examination of section 71's ethical guidelines relating to informed consent in the National Health Act, No 61, 2003 in South Africa in order to better serve the interests of South African adolescents in sexual and reproductive health research.

13.  Partner notification 
BMJ Clinical Evidence  2009;2009:1605.
Many people diagnosed with a sexually transmitted disease (STD) do not have symptoms, and may not inform their past or current sexual partners of their diagnosis or routinely use condoms. Several strategies have been used to notify and treat partners of people diagnosed with an STD, but only a limited number of RCTs of their effectiveness have been undertaken.
Methods and outcomes
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of partner notification strategies in people with different STDs? What are the effects of interventions to improve effectiveness of patient referral in people with STDs? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
We found 17 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
In this systematic review, we present information relating to the effectiveness and safety of the following interventions: contract referral; counselling (both alone and in combination with educational interventions) of index patients; educational interventions for the index patient; information for the index patient or partner; outreach assistance; patient referral; patient referral via different types of healthcare professional; patient-delivered partner therapy; patient-delivered home-sampling kits; provider referral; and reminders (any format) for the index patient.
Key Points
Many people diagnosed with an STD do not have symptoms, and may not inform their past or current sexual partners of their diagnosis, or routinely use condoms.
Several strategies have been used to notify and treat partners of people diagnosed with STDs, but only a limited number of RCTs of their effectiveness have been undertaken.
Patient referral is where the index patient is encouraged to inform their past and present partners.
Provider referral is where health professionals notify the partner without disclosing the identity of the index patient, and outreach assistance is where members of an outreach team indigenous to the community notify the partner without disclosing the identity of the index patient.
Contract referral is where the index patient is encouraged to notify their partners, but the health professional does so if they fail to attend for treatment within an allotted time.
Various methods are used to improve patient referral, including: patient-delivered partner therapy; home sampling kits; information, education, reminders, and counselling for the index patient; and the use of different healthcare professionals.
Contract referral may lead to more partners of people with HIV infection being notified compared with patient referral alone. We don't know whether provider referral or outreach assistance are beneficial in tracing partners of people with HIV.
Contract referral may increase the proportion of partners presenting for treatment compared with patient referral in people with gonorrhoea. We don't know whether either provider referral or outreach assistance are effective partner notification strategies in people with gonorrhoea.
Provider referral may increase the proportion of partners treated compared with patient referral in people with chlamydia. We don't know whether either contract referral or outreach assistance are effective partner notification strategies in people with chlamydia.
Contract referral strategies seem to be as effective as provider referral in people with syphilis, with similar proportions of partners of people with syphilis being notified with each strategy. We don't know whether either patient referral or outreach assistance are effective partner notification strategies in people with syphilis.
Supplementing patient referral with patient-delivered partner therapy may reduce the risk of persistent or recurrent infection in index patients with chlamydia or gonorrhoea. Supplementing patient referral with patient-delivered partner therapy seems to improve the proportion of partners elicited who received treatment compared with supplementation with written information for partners in people with chlamydia or gonorrhoea infections.
In people with chlamydia, home-sampling kits for partners seem to increase the number of partners who are tested for infection compared with simple patient referral.
We don't know whether supplementing patient referral with health education or counselling, either alone or in combination, for index patients improves the number of partners tested or treated.
We don't know whether adding telephone reminders plus counselling, reminders for the index patient, or information pamphlets to patient referral improves partner notification rates, or whether different health professionals are more effective at improving patient referral rates.

14.  The failure of routine rapid HIV testing: a case study of improving low sensitivity in the field 
The rapid HIV antibody test is the diagnostic tool of choice in low and middle-income countries. Previous evidence suggests that rapid HIV diagnostic tests may underperform in the field, failing to detect a substantial number of infections. A research study inadvertently discovered that a clinic rapid HIV testing process was failing to detect cases of established (high antibody titer) infection, exhibiting an estimated 68.7% sensitivity (95% CI [41.3%-89.0%]) over the course of the first three weeks of observation. The setting is a public service clinic that provides STI diagnosis and treatment in an impoverished, peri-urban community outside of Cape Town, South Africa.
The researchers and local health administrators collaborated to investigate the cause of the poor test performance and make necessary corrections. The clinic changed the brand of rapid test being used and later introduced quality improvement measures. Observations were made of the clinic staff as they administered rapid HIV tests to real patients. Estimated testing sensitivity was calculated as the number of rapid HIV test positive individuals detected by the clinic divided by this number plus the number of PCR positive, highly reactive 3rd generation ELISA patients identified among those who were rapid test negative at the clinic.
In the period of five months after the clinic made the switch of rapid HIV tests, estimated sensitivity improved to 93.5% (95% CI [86.5%-97.6%]), during which time observations of counselors administering tests at the clinic found poor adherence to the recommended testing protocol. Quality improvement measures were implemented and estimated sensitivity rose to 95.1% (95% CI [83.5%-99.4%]) during the final two months of full observation.
Poor testing procedure in the field can lead to exceedingly low levels of rapid HIV test sensitivity, making it imperative that stringent quality control measures are implemented where they do not already exist. Certain brands of rapid-testing kits may perform better than others when faced with sub-optimal use.

16.  The impact of provider-initiated (opt-out) HIV testing and counseling of patients with sexually transmitted infection in Cape Town, South Africa: a controlled trial 
The effectiveness of provider-initiated HIV testing and counseling (PITC) for patients with sexually transmitted infection (STI) in resource-constrained settings are of particular concern for high HIV prevalence countries like South Africa. This study evaluated whether the PITC approach increased HIV testing amongst patients with a new episode of sexually transmitted infection, as compared to standard voluntary counseling and testing (VCT) at the primary care level in South Africa, a high prevalence and low resource setting.
The design was a pragmatic cluster-controlled trial with seven intervention and 14 control clinics in Cape Town. Nurses in intervention clinics integrated PITC into standard HIV care with few additional resources, whilst lay counselors continued with the VCT approach in control clinics. Routine data were collected for a six-month period following the intervention in 2007, on new STI patients who were offered and who accepted HIV testing. The main outcome measure was the proportion of new STI patients tested for HIV, with secondary outcomes being the proportions who were offered and who declined the HIV test.
A significantly higher proportion of new STI patients in the intervention group tested for HIV as compared to the control group with (56.4% intervention versus 42.6% control, p = 0.037). This increase was achieved despite a significantly higher proportion intervention group declining testing when offered (26.7% intervention versus 13.5% control, p = 0.0086). Patients were more likely to be offered HIV testing in intervention clinics, where providers offered the HIV test to 76.8% of new STI patients versus 50.9% in the control group (p = 0.0029). There was significantly less variation in the main outcomes across the intervention clinics, suggesting that the intervention also facilitated more consistent performance.
PITC was successful in three ways: it increased the proportion of new STI patients tested for HIV; it increased the proportion of new STI patients offered HIV testing; and it delivered more consistent performance across clinics. Recommendations are made for increasing the impact and feasibility of PITC in high HIV prevalence and resource-constrained settings. These include more flexible use of clinical and lay staff, and combining PITC with VCT and other community-based approaches to HIV testing.

17.  Community perspectives on the ethical issues surrounding adolescent HIV vaccine trials in South Africa 
Vaccine  2008;26(45):5679-5683.
Adolescents globally are at high risk for HIV acquisition and are the targets of HIV prevention interventions such as HIV vaccines. In order to understand stakeholders’ attitudes towards the ethical issues of adolescent involvement in HIV vaccine trials, we conducted focus group discussions with key members of a semi-urban, informal Cape Town community with high HIV prevalence in which HIV vaccine trials are taking place. Themes were identified from focus group transcripts by four researchers, and included necessity of guardian consent, age of independent consent, and confidentiality of in-trial medical results. In general, ethical adolescent HIV vaccine trials will be feasible in this community.
