A deal to buy enough vaccines to give every adult a fourth dose of protection against covid has been signed by the UK government.Sajid Javid, the UK Health Secretary, confirmed that deals for 114 million extra doses of Pfizer and Moderna have been accelerated in light of fears over the new Omicron variant.
The new deals for 2022 and 2023 include access to modified vaccines if existing jabs are found to be less effective against the worrying new strain.
The figures involved suggest UK residents could be offered a fourth dose even as they are now being encouraged to get their third booster jab against the new strain of covid.
