English official says COVID-19 transmission highest in children

England's Chief Medical Officer Chris Whitty on Wednesday said that children were currently driving transmission of COVID-19 at the moment, and that without vaccination, almost all 12- to 15-year-olds would get infected at some point.

"There is definitely substantial transmission happening in this age group. In fact, the age group we're talking about is the one in which the highest rate of transmission is currently occurring, as far as we can tell," Whitty told lawmakers at a session about the decision to offer COVID-19 vaccines to children aged 12-15.

"Virtually any child, unvaccinated, is likely to get an infection at some point between 12 and 15."
