The Trend of COVID-19 Vaccination Rate and Its associated factors: a multicenter household survey (Preprint)

Abstract

BACKGROUND Vaccination against COVID-19 has saved tens of thousands of lives worldwide since its introduction. However, with time elapsing, improving the vaccination coverage in China may be confronted with a number of obstacles. OBJECTIVE In this nationwide study, we aimed to evaluate the COVID-19 vaccination rate and its potential influencing factors in the Chinese population. METHODS We collected data from the national multicenter household survey in China using a stratified random sampling method from 3 Aug. 2022 to 14 Aug. 2022. We recruited respondents aged 18 years or older in the selected households. We investigated the variation in the COVID-19 vaccination rate for the first dose, full dose as well as the booster vaccine, and identified the associated factors for vaccination using multiple logistic regression models. RESULTS A total of 6781 participants (2556 households) were included in this study. Up to 14 Aug. 2022, 6613 participants (97.52%, 95%CI: 97.15%-97.89%) received the first dose of COVID-19 vaccines; 6319 participants (93.19%, 95%CI: 92.59%-93.79%) received the full-dose vaccines while 5435 participants (80.15%, 95%CI: 79.20%-81.10%) received the COVID-19 booster vaccines. Participant’s age, chronic disease status and self-efficiency were found to be significant influencing factors for receiving first dose vaccine, full dose vaccine and booster dose vaccine for COVID-19. Ineligibility for vaccination was the primary reason that participants did not receive the booster vaccine (74.98%). This is followed by vaccination safety concerns, which make up 8% of all the highlighted reasons. CONCLUSIONS China has surpassed initial targets of WHO's Global COVID-19 Vaccination Strategy. To increase vaccine coverage, policymakers should develop more specialized measures for special groups, including young adults, people with chronic disease, and those with low self-efficacy. CLINICALTRIAL Not applicable.

Impasses and Nuances of Vaccination for COVID-19 in Children Aged 5-11 Years

“…This stance is one of the biggest threats to global health today. The prevalence of acceptance of vaccination in developed countries such as the USA, France and Italy is less than 60%, exhibiting lower values in places such as Russia, the Middle East and African countries [6]. Several studies have shown that this hesitation becomes more important when it comes to vaccinating children and adolescents [7][8][9][10].…”
