Prime Minister Boris Johnson has hinted that more people will be offered a third booster Covid jab - lowering the age from the current 40.
He also said the time between the second and third jab will be reduced.
Mr Johnson said: “Third, and most importantly, we need to bolster our protections against this new variant.
“We don’t yet exactly know how effective our vaccines will be against Omicron but we have good reasons for believing they will provide at least some measure of protection.
“If you’re boosted, your response is likely to be stronger so it’s more vital than ever that people get their jabs and we get those boosters into arms as fast as possible.
“From today we’re going to boost the booster campaign, we’re already planning to do six million jabs in England alone over the next three weeks and now we’re looking to go further.
“The Health Secretary has asked the JCVI (Joint Committee on Vaccination and Immunisation) to consider giving boosters to as wide a group as possible as well as reducing the gap between your second dose and your booster.”
