BACKGROUND: Men who have sex with men (MSM) and transgender women (TGW) are at elevated mpox risk; vaccination can greatly reduce that risk. We assessed mpox awareness and vaccine acceptability among MSM and TGW.
METHODS: In 2022, hybrid-mode (offline/online) surveys were administered among 250 MSM and 251 TGW in Chennai, India. Robust Poisson regression models were used to identify predictors of mpox awareness and vaccine acceptability.
RESULTS: Participants' mean age was 29.1 years; the mean monthly income was 192 in US dollars. More than half (54.5%) had a college/diploma degree, 29% of MSM and 90% of TGW reported engaging in sex work in the past month, and 49% of MSM and 86% of TGW reported inconsistent condom use with male partners. Overall, 59% had heard of mpox; 37% knew of its high burden among MSM/TGW. Vaccine acceptability was 36.7% (MSM, 53.6%; TGW, 19.9%). Mpox awareness was predicted by higher education (prevalence rate ratio [PRR], 1.18; P = 0.04), online recruitment (PRR, 1.28; P = 0.01), preexposure prophylaxis awareness (PRR, 1.30; P < 0.001), and more nonregular male sexual partners (PRR, 1.03 per 10-partner increment; P = 0.01). Mpox vaccine acceptability was positively associated with awareness about high mpox burden among MSM/TGW (PRR, 1.31; P = 0.04) and online recruitment mode (PRR, 1.52; P = 0.001), but negatively with depression (PRR, 0.68; P = 0.02) and inconsistent condom use (PRR, 0.68; P = 0.002). Transgender women were less willing than MSM (PRR, 0.43; P < 0.001).
CONCLUSIONS: Suboptimal mpox awareness and vaccine acceptability among MSM and TGW highlight key vulnerabilities. Tailored, nonstigmatizing educational interventions delivered via community-based organizations, online platforms, and HIV services are needed to address informational and psychosocial barriers. For preparedness, enhancing equitable vaccine access and clinical vigilance may help strengthening India's mpox response.
