Coronavirus latest: ALL kids could get infected with Covid at some point if they aren't vaccinated, Professor Chris Whitty warned on Wednesday afternoon.
England's Chief Medical Officer said without jabs, children between 12 and 15 years old would likely catch the killer virus.
He revealed around half of the UK's kids have already had Covid, adding: "we’re running into winter so there’s still quite a lot of damage that could be done in terms of disruption".
The expert warned that age group is driving the spread of the infection, with schools having gone back and social distancing scrapped.
The teens are also all mostly unvaccinated at the moment, which makes them prime targets for the virus.
Prof Whitty explained: "Virtually any child, unvaccinated, is likely to get an infection at some point between 12 and 15."
He told the Education Committee in Parliament: "Let’s make an assumption that the great majority of children who have not had Covid are going to get it at some point over the next period.
"It won’t be necessarily in the next two or three months but they will get it sooner or later because it is incredibly infectious and because immunity wanes we’re not going to see a situation where it just sort of stops at a certain point.
"So over the next years we will see that happening. Vaccination will reduce that risk by, for the sake of argument, 50 per cent – it’s probably slightly more than that.
"People who’ve already had the infection – some of them will go on to get it a second time, that we know.
"And so the vaccination will further reduce that number and it won’t produce complete protection for those who were vaccinated and so there will be some people who won’t even get infected at all but they will be really a very small number."
He added there is an assumption that vaccines take longer to wane in children than in adults, which is currently thought to be about six months.
It comes after the rollout of Covid jabs for teens began this week in schools.
Kids getting their vaccines will receive a single dose of the Pfizer/BioNTech vaccine.
Jabs are being delivered by local School Age Immunisation Services, as is the case with the flu and HPV vaccines.
Every unvaccinated child will get Covid, Chris Whitty warns
