Children aged between five and 11 in England will be offered a low-dose Covid vaccine, the government says.
Official scientific advice concludes the move would help protect the “very small” number of children who become seriously ill with Covid.
Health Secretary Sajid Javid says the rollout will be “non-urgent”, with an emphasis on parental choice.
Northern Ireland also said on Wednesday it will be following Wales and Scotland in offering young children the vaccine.
Children are at a much lower risk of becoming severely ill from a Covid infection, so the health benefits of vaccinating them are smaller than in other age-groups. Also, many will have some protection from already having caught the virus.
So the scientists on the Joint Committee on Vaccination and Immunisation (JCVI), which advises governments across the UK, have been weighing up the evidence for immunising five to 11-year-olds.
It concluded vaccination should go ahead to prevent a “very small number of children from serious illness and hospitalisation” in a future wave of Covid.
Prof Wei Shen Lim, from the JCVI, said: “We’re offering this to five to 11-year-olds now in order to future-proof their defences against a future wave of infection.”
He suggested parents consider getting their children vaccinated during school holidays to minimise disruption to their education from any flu-like side effects of the jab.
The full guidance says fewer than two children would develop inflamed heart muscle (myocarditis) out of every million vaccinated.
However, it estimates vaccinating one million children would prevent:
- 98 hospitalisations if the next wave was more severe like previous variants
- 17 hospitalisations if the next wave was relatively mild, like Omicron
Prof Lim warned other childhood vaccinations include the MMR and HPV campaigns have “fallen behind due to the pandemic” and it was “vital” that Covid jabs did not disrupt these immunisations.
Mr Javid said: “The NHS will prepare to extend this non-urgent offer to all children during April so parents can, if they want, take up the offer to increase protection against potential future waves of Covid-19 as we learn to live with this virus.”
He emphasised that children are at low risk from Covid and that the “priority remains for the NHS to offer vaccines and boosters to adults and vulnerable young people” and to catch-up with other childhood immunisation programmes”.
