People over 50 and the most vulnerable could get a Pfizer jab this autumn as part of a booster programme ahead of the winter months.
Millions of Brits are expected to be offered third Covid jabs to shore up protections against the virus under interim advice from the Joint Committee on Vaccination and Immunisation (JCVI).
The plan, first announced at the end of June, would see the over 70s, the clinically vulnerable, care home residents, and front line NHS and care staff among the first to get a booster.
Over-50s and anyone entitled to a free flu jab would be next in line if the JCVI experts confirm the move in their final advice this month.
The Daily Telegraph reports that the rollout of booster jabs will start in September, with the aim of all over-50s receiving one by two weeks before Christmas.
It has also been suggested that people could be offered the Pfizer vaccine as a booster, regardless of whether they have previously received the Oxford AstraZeneca jab.
But No10 said reports in the Daily Mail that all patients will be offered Pfizer as it is the most effective against the Delta variant were “premature”.
