Willingness to receive measles-containing vaccine among healthcare workers / 预防医学

ABSTRACT

Objective@#To investigate the willingness to receive measles-containing vaccine (MCV) and its influencing factors among healthcare workers in the Yangtze River Delta region, so as to provide the evidence for improving the measles-containing vaccination rate@*Methods@#Healthcare workers were sampled from 19 medical institutions in each of Shanghai Municipality, Jiangsu Province, Zhejiang Province and Anhui Province for questionnaire surveys using a multi-stage stratified convenience sampling methods from July 2020 to March 2021. Participants' gender, age, educational level, professional title, measles-containing vaccination, awareness of MCV and willingness to receive MCV were collected, and the factors affecting the willingness to receive MCV were identified among healthcare workers using a multivariable logistic regression model. @*Results@#Totally 1 403 questionnaires were allocated, and 1 394 valid questionnaires were recovered, with an effective recovery rate of 99.36%. The respondents included 327 men and 1 067 women, with a male to female ratio of 1∶3.26, and 64.35% (897) were at ages of 31 to 50 years. There were 1 005 respondents with a bachelor degree (72.09%), 765 with middle and senior professional titles (54.88%), 676 with a history of measles-containing vaccination (48.49%), 1 176 with willingness to receive MCV (84.36%) and 218 without willingness to receive MCV due to convenience of vaccination (30.73%) and cost (19.27%). Multivariable logistic regression analysis showed that region (Zhejiang, OR=1.613, 95%CI 1.054-2.470; Anhui, OR=2.058, 95%CI 1.259-3.363), and no history of measles (OR=2.219, 95%CI 1.302-3.781) were factors improving the willingness to receive MCV among healthcare workers, and hospital level (secondary, OR=0.483, 95%CI 0.306-0.763; tertiary, OR=0.251, 95%CI 0.160-0.394), history of measles-containing vaccination (no, OR=0.262, 95%CI 0.172-0.399; unknown, OR=0.386, 95%CI 0.266-0.559), and unawareness of MCV knowledge (OR=0.208, 95%CI 0.081-0.536) were factors inhibiting the willingness to receive MCV among healthcare workers.@*Conclusions@#The willingness to receive MCV correlates with region, history of measles, hospital level, history of measles-containing vaccination and awareness of MCV knowledge among healthcare workers in the Yangtze River Delta region.
