Aim: A severe outbreak of monkeypox occurred worldwide in 2022, particularly affecting sexual and gender minorities. This study aimed to explore the adverse physical and psychological events associated with different monkeypox vaccination regimens.
Methods: A cross-sectional online survey was conducted from May to June 2023, targeting adults scheduled for their second dose of pre-exposure prophylaxis vaccine against monkeypox, with participants recruited from a medical center in Taiwan. The questionnaire focused on the physical and psychological impacts of the first monkeypox vaccination, with the preferences of the participants for the vaccination regimens of the second vaccination and the factors influencing their preferences also inquired.
Results: A total of 2,827 respondents completed the questionnaire. Among physical impacts, common adverse systemic events included fatigue, myalgia, and headache, while common adverse local events included skin discoloration, erythema, swelling, and itchiness. Intradermal injection in the forearm was associated with a higher incidence of local adverse reactions, especially skin discoloration, leading to varying degrees of physical and psychological impacts. “Beauty,” “scar,” and “perceptions of others” emerged to be the most significant factors influencing preferences for vaccination regimens.
Conclusion: This study identified a range of adverse systemic and local reactions associated with different monkeypox vaccination regimens. Understanding the factors influencing preferences for vaccination regimens is crucial for alleviating the physical and psychological stress of vaccine recipients.
