Background There are no pharmacological interventions currently available to prevent the transmission of SARS-CoV-2 or to treat COVID-19. The development of vaccines against COVID-19 is essential to contain the pandemic. we conducted a cross-sectional survey of Shanghai residents to understand residents’ willingness to be vaccinated with any future COVID-19 vaccines and take measures to further improve vaccination coverage. Methods We conducted a cross-sectional survey using self-administered anonymous questionnaires from 1 July to 8 September 2020. The main outcome was willingness of participants, and any children or older individuals living with them, to receive future COVID-19 vaccines. Logistic regression analyses were used to explore potential factors associated with vaccination willingness. Results A total of 1071 participants were asked about their willingness to receive future COVID-19 vaccines, for themselves and at least 747 children and 375 older individuals (≥60 years old) living with them. The highest proportion of expected willingness to vaccinate was among participants (88.6%), followed by children (85.3%) and older individuals (84.0%). The main reasons for reluctance to vaccinate among 119 participants were doubts regarding vaccine safety (60.0%) and efficacy (28.8%). Participants with a self-reported history of influenza vaccination were more likely to accept COVID-19 vaccines for themselves [adjusted odds ratio ( OR ) = 1.83; 95% confidence interval ( CI ): 1.19–2.82], their children (adjusted OR = 2.08; 95% CI : 1.30–3.33), and older individuals in their household (adjusted OR = 2.12; 95% CI : 1.14–3.99). Participants with older individuals in their families were less willing to vaccinate themselves (adjusted OR = 0.59; 95% CI : 0.40–0.87) and their children (adjusted OR = 0.58; 95% CI : 0.38–0.89). Conclusions Participants were more reluctant to accept COVID-19 vaccines for older individuals living with them. The presence of older individuals in the home also affected willingness of participants and their children to be vaccinated.
