A single dose of the Pfizer Covid-19 vaccine can reduce infections among children, a new study suggests. And if a child gets Covid-19 after being vaccinated they are "likely to have a milder disease", researchers from King's College London and ZOE Ltd said.
While the Covid-19 vaccines have been shown to ward off serious disease and death, questions have arisen over their ability to reduce the spread of infections. The latest study examined the effectiveness of a single dose of the Pfizer/BioNTech Covid vaccine in children.
Researchers examined information on 115,775 children aged 12 to 17 through the Covid Symptom Study app. They looked at data between August 5, 2021, and February 14 this year - meaning that the study looked at effectiveness of the jab as different variants swept the UK.
