Despite its scaled-up response for prevention of mother-to-child transmission of HIV (PMTCT), Nigeria still contributes the greatest number of infants infected with HIV worldwide. Drawing on our knowledge, and review of policy documents and research papers, we explored the achievements and challenges in the elimination of mother-to-child transmission of HIV in Nigeria using the WHO’s health systems framework. We found that Nigeria has increased the number of PMTCT sites, decentralized and integrated PMTCT care for expanded service delivery, adopted task-shifting to address the shortage of skilled healthcare providers, explored alternative sources of domestic funding to bridge the funding gap and harmonized the health management information system to improve data quality. Some of the challenges we identified included: difficulty in identifying HIV-infected pregnant women because of low uptake of antenatal care; interrupted supplies of medical commodities; knowledge gaps among healthcare workers; and lack of a national unique identifying system to enhance data quality. While there have been some achievements in the PMTCT program, gaps still exist in the different blocks of the health system. Elimination of mother-to-child transmission of HIV in Nigeria will require the implementation of feasible, culturally acceptable and sustainable interventions to address the health system-related challenges.

Social marketing campaigns have been increasingly used in HIV prevention efforts to address barriers to HIV testing. The purpose of this review is to evaluate the social marketing campaigns in the past ten years (2008-2017) that have targeted HIV testing or intent to test as an outcome, and synthesize the results to determine which campaigns work or do not work. The search was conducted using PubMed, Scopus, PsycINFO, EMBASE, and ABI/Inform. The quality assessment tool for quantitative studies developed by the Effective Public Health Practice Project was used to assess study quality. The search generated 373 articles, of which 13 articles met the inclusion criteria. These articles were from 13 distinct campaigns carried out in 9 countries, twelve of which were in high income countries. Sixty-nine percent (n = 9) of the campaigns targeted MSM, gay men, or MSMW, 23% (n = 3) targeted the general population, while 8% (n = 1) focused on African-American women. The study designs for evaluating the campaigns were predominantly cross-sectional, with 4 of the articles combining two or three study designs to evaluate their campaign. Overall, 38% (n = 5) of the campaigns had an increase in HIV testing outcomes, 23% (n = 3) reported no change in HIV testing outcomes, and the remaining 38% (n = 5) of the studies reported mixed outcomes. The results of the quality rating showed that 69% (n = 9) of the papers had weak global ratings, while 31% (n = 4) had moderate rating. None of the articles had a strong rating. This review displayed that social marketing campaigns intended to increase HIV testing uptake were effective in some context. Social marketing practitioners will need to come up with a standardized way of communicating the results of campaign exposure and impact so as to enhance comparison among the multitude of campaigns.

Background: The highest-income countries procured 50 times as many COVID-19 vaccines as low-income countries, a global health inequity that resulted in only 4.6% of the poorest 5th of the world receiving a COVID-19 vaccine. High-income countries are considering vaccine mandates and passports to contain the spread of COVID-19. This study is a curated discourse aimed at examining how vaccine mandates and passports may impact global vaccine equity from an ethics perspective. Study Design: Narrative review adapted for a debate. Methods: In November 2021, we conducted a review of studies examining global vaccine mandates for an upper-level global health course at Northeastern University, Boston, United States (U.S.). In total, 19 upper-level students, one research assistant, and one instructor participated in the data collection, analysis, and discussion. Results: The review showed vaccine mandates are ethical and effective if autonomy-centered alternatives like soft mandates are first exhausted. Unwarranted stringent public health measures degrade public trust. In the U.S. alone, COVID-19-related deaths hovered above 300000 before COVID-19 vaccination began in mid-December 2020. Since then, the number of COVID-19 deaths more than doubled, despite the wide availability of the vaccine. For many low- and middle-income countries (LMICs) vaccines are not available or easily accessible. Global collaboration to facilitate vaccine availability in LMICs should be a priority. Conclusions: It is essential to get as many people as possible vaccinated to return to some normality. However, vaccine mandates and passports need to be used only sparingly, especially when other options have been exhausted.

Partner HIV testing during pregnancy has remained abysmally low in sub-Saharan Africa, particularly in Nigeria. Males rarely attend antenatal clinics with their female partners, limiting the few opportunities available to offer them HIV testing. In this study, we evaluated the scale-up of the Healthy Beginning Initiative (HBI), a community-driven evidenced-based intervention to increase HIV testing among pregnant women and their male partners. Our objectives were to determine the: (1) male partner participation rate; (2) prevalence of HIV among male partners of pregnant women; (3) factors associated with HIV positivity among male partners of HIV-positive pregnant women. We reviewed program data of expectant parents enrolled in HBI in Benue State, north-central Nigeria. During HBI, trained lay health workers provided educational and counseling sessions, and offered free onsite integrated testing for HIV, hepatitis B virus and sickle cell genotype to pregnant women and their male partners who participated in incentivized, church-organized baby showers. Each participant completed an interviewer-administered questionnaire on demographics, lifestyle habits, and HIV testing history. Chi-square test was used to compare the characteristics of HIV-positive and HIV-negative male partners. Simple and multivariable logistic regression models were used to determine the association between participants' characteristics and HIV positivity among male partners of HIV-positive women. Male partner participation rate was 57% (5264/9231). Overall HIV prevalence was 6.1% (891/14495) with significantly higher rates in women (7.4%, 681/9231) compared to men (4.0%, 210/5264). Among the 681 HIV-positive women, 289 male partners received HIV testing; 37.7% (109/289) were found to be HIV-positive. In multivariate analysis, older age (adjusted odds ratio [aOR]: 2.45, 95% confidence interval [CI]: 1.27–4.72 for age 30–39 years vs. <30 years; aOR: 2.39, CI: 1.18–4.82 for age ≥40 years vs. <30 years) and self-reported daily alcohol intake (vs. never (aOR: 0.35, CI: 0.13–0.96)) were associated with HIV positivity in male partners of HIV-positive women. The community-based congregational approach is a potential strategy to increase male partner HIV testing towards achieving the UNAIDS goal of 90% HIV screening. Targeting male partners of HIV-positive women for screening may provide a higher yield of HIV diagnosis and the opportunity to engage known positives in care in this population.
