This study is aimed at assessing the willingness to participate in the HIV vaccine trials and the associated factors among people who inject drugs (PWIDs) in Tanzania. Information about the willingness to participate and the associated factors was collected using interviewer-administered questionnaires at the medication treatment for opioid use disorder (MOUD) clinic in Dar es Salaam. Data analysis was performed using the IBM SPSS Statistic 20. The mean age of respondents was 36.7, and the standard deviation (SD) was ±7.2. The majority of respondents (68%) had primary education, and a high proportion of them were single (61.5%). More than one-third (37.9%) shared needles and syringes. Most (87.3%) had more than three sexual partners, and almost half (51.4%) did not use condoms during sexual intercourse with nonregular partners. About 63% had knowledge of HIV transmission while 27% had heard about HIV vaccine trials. Generally, 76% of the respondents expressed willingness to participate in future HIV vaccine trials regardless of prior knowledge of HIV vaccine trials. Willingness to participate in HIV vaccine trials was not associated with education level, people living with, knowledge about HIV transmission, awareness of HIV vaccine trials, sharing of syringe/needles, and number of sexual partners. Only older age (OR=1.6, 95%CI=1.01, 2.6) and condom use (OR=0.49, 95%CI=0.26, 0.97) showed an association with willingness. However, after performing logistic regression with factors at p value ≤ 0.2 to ascertain the other factors on the effects of age, condom use, education level, and sharing of needles/syringes, the results were not statistically significant. Although participants reported a high willingness to participate in hypothetical HIV vaccine trials, no definitive conclusion can be drawn about the associated factors. Further studies with intensive educational programs are needed to investigate the factors on willingness to participate in actual HIV vaccine trials among PWIDs.

 Background: Despite the successful conduct of three Phase I/II HIV vaccine trials in Dar es Salaam, Tanzania, misperception around the trials has been reported. In this study, misperception means incorrect understanding that in Phase I/II HIV vaccine trial, the researchers infected the volunteers with HIV. We describe the magnitude of misperception around HIV vaccine trials and associated factors among participating communities in Dar es Salaam, Tanzania. Methods: We conducted a cross-sectional study that included 605 respondents aged ³18 years from the communities that participated in Phase I/II HIV vaccine trials. These communities comprised of youths, Police and Prison officers. Respondents were interviewed using a pre-tested questionnaire on socio-demographic characteristics, HIV knowledge, and responses to HIV vaccine trial related questions. Results: Of the 605 respondents, 156 (26%) had misperception that the researchers infected the volunteers with HIV during the trials, while 58% weren’t sure whether the researchers infected the volunteers with the HIV or not. Awareness about progress in HIV vaccine development (adjusted risk ratio (RR)=1.50; 95% CI=1.11 – 2.04), participation in an HIV vaccine sensitization meeting (adjusted RR=1.50; 95% CI=1.14-1.97) and advanced secondary education (adjusted RR=1.92; 95% CI=1.19 – 3.09) were associated with an increased likelihood of having the misperception that researchers infected the volunteers. Nevertheless, the majority (94.5%) of respondents showed a willingness to know more about ongoing HIV vaccine studies while about 44.3% had reservations of taking part in HIV vaccine trials due to fear of getting HIV from the vaccine. Conclusions: The misperception that researchers infected volunteers with HIV in Phase I/II trial is significant and was associated with respondents’ awareness about HIV vaccine development, participation in sensitization meetings and advanced education. Partial knowledge about HIV vaccine trials was of note. Future HIV vaccine trials should strive to address the knowledge gap.

Research on willingness to participate in HIV vaccine trials is important in preparations for HIV vaccine research, but there are few data from sub-Saharan Africa. We interviewed 198 individuals in a peri-urban South African community immediately after enrolment into an HIV vaccine preparedness study on their willingness to participate in hypothetical vaccine trials. Overall 23% of participants ( n = 46) said that they would be willing to participate in an HIV vaccine trial. Willingness was associated with increasing age, male gender, and increasing knowledge about vaccines generally and HIV vaccines specifically. In multivariate analysis, a 1-unit increase in HIV vaccine knowledge score was associated with a 10-fold increase in willingness to participate (adjusted odds ratio, 10.72, 95% confidence intervals: 4.40–26.12). These results suggest that while willingness to participate in HIV vaccine trials is relatively low in this setting, educational campaigns may have a substantial impact on individuals' willingness to participate in research.

This study aimed to determine and describe HIV-negative gay men's willingness to participate in HIV vaccine trials. Data were from participants who completed face-to-face interviews during the first 18 months (to the end of 2002) of recruitment into the Health in Men cohort of HIV-negative gay men in Sydney. A key outcome measure was a scale of Willingness to Participate in HIV Vaccine Trials, with scores ranging from 1 (unwilling) to 4 (willing). The 903 participants ranged in age from 18 to 75years (median=36). Mean of Willingness to Participate in HIV Vaccine Trials was 2.53 (standard deviation=0.54), with approximately 51% of the men having a score greater than the midpoint of 2.50. A reduced linear regression model yielded four significant independent associations with Willingness to Participate in HIV Vaccine Trials: lack of tertiary education ( P <0.001),having engaged 'in the previous six months' in any unprotected anal intercourse with casual or non-concordant regular partners ( P <0.001), higher self-rated likelihood of HIV infection ( P <0.01), and higher mean scores on a scale of Comfort with Participation in HIV VaccineTrials ( P <0.001). The willingness of HIV-negative gay men at potentially higher risk for HIV to participate in HIV vaccine trials augurs well for enrolment in HIV vaccine efficacy trials. Recruitment into trials is likely to be enhanced by addressing salient concerns such as confidentiality and vaccine-induced antibody positivity. Also, it will be important to ensure that gay men are educated and fully informed about HIV vaccines and trial processes.
