Covid vaccines effective against severe cases in children, study finds

The study shows that despite most children having been infected and severe infection could occur, deaths were extremely rare in children.

Vaccines are effective against severe cases of COVID-19 in children and adolescents, according to a review of studies.

However, the study published in the journal BMJ Paediatrics Open shows that with most children already infected with the SARS-CoV-2 virus and building up a natural immunity, the additional benefit of vaccination in healthy children is minimal.

The team, led by researchers at the Murdoch Children’s Research Institute in Australia, explored the challenges and considerations of COVID-19 vaccination, especially in low- and middle-income countries with high levels of community transmission and infection-derived immunity.
