Matt Hancock said third doses of vaccines would be deployed in months
Health Secretary Matt Hancock confirmed the Government was already looking at how to deliver new jabs.
It comes after fears mutations first identified in South Africa and Brazil could be resistant to the current antidotes being administered.
Mr Hancock told MPs: "The biggest risk to our progress here in the UK is a new variant that the vaccine does not work as well against.
"We know from our response to other viruses like flu that we need updated vaccines to tackle mutated viruses.
So, I can tell the House that as we complete the programme of first and second jabs, we are ramping up plans for a booster shot to make sure our vaccines stay ahead of the virus."
The Health Secretary said the third injections would take place "later this year" with the Government having already ordered enough jabs to give a booster shot to all adults.
"We will be working with our current vaccine suppliers and new vaccine suppliers like the CureVac partnership to work out which vaccines will be effective as a booster shot and to design new vaccines specifically targeted at the variants of concern like the variant first found in South Africa," he added.
"Our goal is to ensure the vaccine protects against this dreadful disease whatever it throws at us to keeps us safe, and to protect our much-cherished return to a normal way of life."
