Vaccination With Routine Childhood Vaccines and Severity of COVID-19 Among Children in Delhi

OBJECTIVE: To study the association between routine childhood vaccination and the severity of COVID-19 among children. METHODS: A cross-sectional study was undertaken among 141 children (aged ≤15 years), tested positive for SARS-CoV-2 infection. RESULTS: COVID-19 severity (combined moderate and severe) was significantly more in males (14.5%) than females (3.8%), and in those who did not receive first and second dose of MR vaccine (57.1%, and 40%, respectively) than who received (6.3%, and 6.1%, respectively). Disease severity was more in partially immunized children (16.7%) as compared to fully immunized children (7.0%). CONCLUSIONS: Children who did not receive both doses of MR vaccine had a severe infection when compared to those who were vaccinated.
