Impact of COVID-19 on Routine Immunization Services

24 Dec 2021

The COVID-19 pandemic has revealed the vulnerability of immunisation systems worldwide, although the scale of these disruptions has not been described at a global level. This study assesses the impact of COVID-19 on routine immunisation using triangulated data from global, country-based, and individual-reported sources obtained during the pandemic period. It finds that there was a decline in the number of administered doses of DTP3 and the first dose of measles-containing vaccine (MCV1) in the first half of 2020. The lowest number of vaccine doses administered was observed in April, 2020, when 33% fewer DTP3 doses were administered globally, ranging from 9% in the WHO African region to 57% in the South-East Asia region. Recovery of vaccinations began by June, 2020, and continued into late 2020. The marked magnitude and global scale of immunisation disruption evokes the dangers of vaccine preventable disease outbreaks in the future. Trends indicating partial resumption of services highlight the urgent need for ongoing assessment of recovery, catch-up vaccination strategy implementation for vulnerable populations, and ensuring vaccine coverage equity and health system resilience. This is a useful study for policymakers.
