Effectiveness of Catch-Up Vaccinations after COVID-19 Containment — China, 2020

Abstract

Introduction: In the early stages of the coronavirus disease 2019 (COVID-19) epidemic in China, the highest level of public health emergency response (Level 1 Response) was launched in all province-level administrative divisions (PLADs) across the country. Provision of vaccination services was selectively suspended due to the physical distancing and gathering restrictions required of the Level 1 Response. The purpose of this paper is to evaluate the impact of COVID-19 on vaccination services and the effectiveness of selective vaccination service suspension and catch-up vaccinations in China.
