Lower rate of mpox vaccination hesitancy and medical consultation among Chinese men who have sex with men living with HIV in comparison with those living without HIV: A national observational study

Abstract

ABSTRACT This anonymous cross-sectional study aimed to investigate the relationships between HIV infection and mpox-related focus issues among Chinese men who have sex with men (MSM). This study involved in 27 MSM social organizations and was conducted from July 31 to August 4, 2023. Mpox vaccination hesitancy was defined as the proportion of participants who expressed unwillingness to receive self-funded and free vaccines. Logistic regression models were employed to estimate odds ratios (OR) and 95% confidence interval (95%CI). Of 7196 MSMs, the prevalence of mpox differed between people living with HIV (PLWH) (1.04%, 20/1920) and people living without HIV (PLWoH) (0.55%, 29/5276) (P = .037). However, after adjusting for all covariates, there was no significant association between HIV status and mpox (aOR = 1.17; 95%CI = 0.58, 2.39; P = .658). Furthermore, the crude rates of vaccination hesitation (PLWoH: 5.91%, PLWH: 4.11%; P = .004) and consultation hesitation (PLWoH: 16.22%, PLWH: 10.78%; P < .001) were both lower in the PLWH. Compared with PLWoH, PLWH had lower odds ratios of vaccination hesitation (aOR = 0.70; 95%CI = 0.53, 0.92; P = .011) and consultation hesitation (aOR = 0.74; 95%CI = 0.60, 0.90; P = .003) among MSM. The estimate of association between HIV status and consultation hesitation was even smaller among MSM who reported hepatitis C infection or uncertainty (aOR = 0.30; 95%CI = 0.15, 0.56), compared with those without hepatitis C (aOR = 0.73; 95%CI = 0.60, 0.89) (P for interaction = .037). MSM living with HIV in China demonstrated a greater willingness to accept mpox vaccination and medical consultation. In the future, it is recommended that medical institutions establish good medical environment to control the mpox epidemic, especially for PLWH.
