Britain is in a 'very good position' against coronavirus variants, researchers insisted today as Pfizer claimed there is no proof its current jab needs to be updated to fight mutant strains.
Public Health England data shows variant cases have remained low in recent weeks, despite a spike in infections triggered by the Indian B.1.617.2 strain.
But Professor Sharon Peacock, who leads the UK's variant tracking programme, said there was no evidence to suggest it triggered more severe disease.
And another Cambridge expert added early studies indicated it was still susceptible to the current crop of vaccines being deployed in Britain.
