the late summer is the soonest point at which under 18's would be given the jab – months earlier than expected.
A Department of Health and Social Care spokesman said "no decisions have been made on whether children should be offered vaccinations".
Prof Adam Finn, a professor of paediatrics at the Bristol Children's Vaccine Centre and member of the Government's joint committee on vaccination and immunisation, said preparations were being made which could allow the rollout of vaccines for children.
He said: "Children constitute close to quarter of the population, so even if we could achieve 100 per cent uptake of vaccines across the adult population, it only gets you to 75 per cent coverage."
BRAVE KIDS
Caleb Chung, who turns 13 later this week, bravely agreed to volunteer for the Pfizer trial. He doesn't know if he received the vaccine or a placebo.
He said in a recent interview with AP: "Usually I'm just at home doing online school and there's not much I can really do to fight back against the virus.
"The study was really somewhere that I could actually help out."
His dad, Dr Richard Chung, a paediatrician at Duke University, said hes proud of his son and all the other children volunteering for the needle pricks, blood tests and other tasks a study entails.
"We need kids to do these trials so that kids can get protected. Adults can't do that for them", he said.
Pfizer is also conducting trials of children aged between six months and 11 years old.
Children rarely get very sick with Covid disease, and there have been barely any deaths in the UK.
But they are carriers of the virus, particularly those who are in secondary school, studies show.
Children are also at risk of long Covid and a serious disease named PIMS, which can cause stomach aches, a rash and even death, several weeks after Covid infection.
It comes after AstraZeneca began a trial of six to 17 years olds in the UK to test the Oxford-made vaccine.
The first vaccinations are underway, with up to 240 children receiving the vaccine and the others receiving a control meningitis jab.
Results of a trial of Moderna’s Covid vaccine in 12 to 17 years olds is expected soon.
