• Increasing women’s vaccine uptake may influence vaccination against COVID-19 for their family members. • People with medical conditions were worried about the compatibility of the vaccine with current medications. • Potential harms associated with COVID-19 vaccines was the most commonly reported concern. • It is important to limit the spread of conspiracy/misinformation on social media. • People identified healthcare providers as a trustworthy source that may influence their vaccine decisions.

Background: Pre-exposure prophylaxis (PrEP) represents a proven biomedical strategy to prevent HIV transmissions among men who have sex with men (MSM) in the United States (US). Despite the design and implementation of various PrEP-focus interventions in the US, aggregated evidence for enhancing PrEP uptake and adherence is lacking. The objective of this systematic review is to synthesize and evaluate interventions aimed to improve PrEP uptake and adherence among MSM in the US, and identify gaps with opportunities to inform the design and implementation of future PrEP interventions for these priority populations. Methods: We followed the PRISMA guidelines and conducted a systematic review of articles (published by November 28, 2021) with a focus on PrEP-related interventions by searching multiple databases (PubMed, MEDLINE, Web of Science and PsycINFO). Details of PrEP interventions were characterized based on their socioecological level(s), implementation modalities, and stage(s) of PrEP cascade continuum. Results: Among the 1363 articles retrieved from multiple databases, 42 interventions identified from 47 publications met the inclusion criteria for this review. Most individual-level interventions were delivered via text messages and/or apps and incorporated personalized elements to tailor the intervention content on participants’ demographic characteristics or HIV risk behaviors. Interpersonal-level interventions often employed peer mentors or social network strategies to enhance PrEP adoption among MSM of minority race. However, few interventions were implemented at the community-, healthcare/institution- or multiple levels. Conclusions: Interventions that incorporate multiple socioecological levels hold promise to facilitate PrEP adoption and adherence among MSM in the US given their acceptability, feasibility, efficacy and effectiveness. Future PrEP interventions that simultaneously address PrEP-related barriers/facilitators across multiple socioecological levels should be enhanced with a focus to tackle contextual and structural barriers (e.g., social determinants of health, stigma or medical mistrust) at the community- and healthcare/institution-level to effectively promote PrEP use for MSM of color.

Introduction: Identification and retention of HIV‐exposed infants in early infant diagnosis (EID) services helps to ensure optimal health outcomes. This systematic review and meta‐analysis examines the magnitude of attrition from EID services in low‐ and middle‐income countries (LMICs).Methods: We performed a comprehensive database search through April 2016. We included original studies reporting retention/attrition data for HIV‐exposed infants in LMICs. Outcomes included loss to follow‐up (LTFU), death and overall attrition (LTFU + death) at time points along the continuum of EID services. At least two authors determined study eligibility, performed data extraction and made quality assessments. We used random‐effects meta‐analytic methods to aggregate effect sizes and perform meta‐regression analyses. This study adhered to PRISMA reporting guidelines.Results: We identified 3040 unique studies, of which 92 met eligibility criteria and were included in the quantitative synthesis. The included studies represent data from 110,805 HIV‐exposed infants, the majority of whom were from Africa (77%). LTFU definitions varied widely, and there was significant variability in outcomes across studies. The bulk of attrition occurred in the first six months of follow‐up, with additional losses over time. Overall, 39% of HIV‐exposed infants were no longer in care at 18 months. When restricted to non‐intervention studies, 43% were not retained at 18 months.Conclusions: These findings underscore the high attrition of HIV‐exposed infants from EID services in LMICs and the urgent need for implementation research and resources to improve retention among this vulnerable population.

To date, existing studies have indicated that stigma against people living with HIV/AIDS (PLWHA) negatively affects their psychosocial well-being, and the impact may differ by age. In the current study, we aim to assess the impact of various types of stigma on PLWHA's psychological status and concomitant substance use. We explored different types of HIV stigma with psychosocial well-being and substance use employing mixed effect models among 2,987 Chinese PLWHA. Multivariate analyses revealed that each type of HIV stigma is positively associated with psychosocial distress, but negatively related to resilience and self-esteem across all age groups of PLWHA, with enacted stigma showing the strongest impact. Stigmatized PLWHA are more likely to smoke and use drugs, especially among the < 35 and 35–49-year-old groups. Age-specific interventions should be implemented to enhance PLWHA's stigma coping skill for improving their psychological health and reducing substance use in China and worldwide.

Introduction: Reducing high‐risk behaviours (i.e. multiple partnership, condomless anal/vaginal sex, alcohol use before sex, illicit drug use) after HIV diagnosis is critical for curtailing HIV transmission. We designed an intervention to explore peer‐ counselling in reducing high‐risk behaviours among newly diagnosed HIV‐positive Chinese men who have sex with men (MSM).Methods: We randomized 367 newly diagnosed HIV‐positive men to either standard‐of‐care (SOC; n = 183) or peer‐counselling intervention (n = 184), and followed them for 12 months (visit at 0‐, 3‐, 6‐, 9‐ and 12‐month). SOC participants received counselling on high‐risk behaviour reduction by clinic staff. Intervention participants received both SOC and peer counselling. A generalized estimating equation was used to compare pre‐post diagnosis high‐risk behaviour change; logistic regression was used to assess the likelihood of practicing high‐risk behaviours between intervention and SOC participants. Both intent‐to‐treat and per‐protocol (full‐dosage) approaches were used for the analyses.Results: For pre‐ and post‐diagnosis comparisons, multiple partnership fell from 50% to 16% (p < 0.001), alcohol use before sex from 23% to 9% (p = 0.001), illicit drug use from 33% to 6% (p < 0.001), condomless anal sex from 47% to 4% (insertive from 23% to 2%; receptive from 36% to 3%; p < 0.001). In the intent‐to‐treat analysis accounting for repeated measures, peer counselling was more likely to reduce insertive anal sex (AOR = 0.65; 95% CI: 0.45 to 0.94), condomless anal sex (AOR = 0.27; 95% CI: 0.10 to 0.64) and illicit drug use (AOR = 0.32; 95% CI: 0.16 to 0.64). In the per‐protocol analysis, peer counselling was associated with a lower likelihood of using illicit drug (OR = 0.23; 95% CI: 0.07 to 0.81) and having condomless vaginal sex with women (OR = 0.12; 95% CI: 0.07 to 0.98).Conclusions: We observed a 14 to 43% decrease in the prevalence of selected high‐risk behaviours after HIV diagnosis. Peer counselling had a greater impact in reducing condomless anal sex with men, illicit drug use and condomless vaginal sex with women over time. Future studies with exclusive peer‐counselling arm are necessary to test its efficacy and effectiveness among Chinese MSM.Clinical Trial Number: NCT01904877
