The Trend of COVID-19 Vaccination Rate and Its associated factors: a multicenter household survey
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. Clinical Trial: Not applicable.
