The study aimed to determine the willingness of medical staff to have their children vaccinated with a COVID-19 booster in Taizhou, China. From March 21 to April 19, 2022, an online questionnaire survey was conducted to assess the willingness of medical staff to vaccinate their children with a booster dose of the COVID-19 vaccine. Of the 1,252 medical staff in a tertiary grade hospital in Taizhou who were invited to answer the structured questionnaire, 514 (41.1%) samples had valid information for further data analysis. Four hundred thirty-seven medical staff (85.0%) were willing to have their children receive vaccine boosters. After adjustments for confounding factors, the opinion ('Do you think your child needs a booster vaccination against COVID-19?') (yes vs. no, OR = 6.91, 95% CI: 3.29-14.54), the viewpoint ('What are your thoughts the effectiveness of COVID-19 vaccine boosters for children?' (≥12 vs. <12, OR = 13.81, 95% CI: 4.03-), and the attitude ('Your attitude to whether your child is boosting the Covid-19 vaccine?') (yes vs. no, OR = 4.66, 95% CI: 2.30-9.44) were significantly associated with their willingness to have their children receive a COVID-19 vaccine booster. A moderate percentage of the respondents expressed willingness to have their children receive booster vaccines. The findings implied that factors affecting medical staffs' willingness to vaccinate their children with a COVID-19 vaccine booster included viewpoint, opinion, and attitudes.
