Ministers should consider extending the plan to give a fourth dose of Covid vaccines to older people because of evidence of waning immunity, scientists say.
The number of people being admitted to hospital with Covid began rising last week, and on 9 March 1,521 were admitted in England – the highest number since the end of January.
Scientists say the rise is because the BA.2 version of Omicron is more transmissible, more people are mixing socially and the effectiveness of booster vaccines is starting to wane.
