Top English medic warns new COVID variants could be more resistant to vaccines

LONDON, Feb 21 (Reuters) – England’s chief medical officer Chris Whitty warned on Monday there will be new COVID-19 variants and said some of them could be more resistant to vaccines.Earlier, Britain said it would end all coronavirus restrictions in England including mandatory self-isolation for people with COVID-19 and free testing, drawing scepticism from some scientists and political opponents.”We all expect… there to be new variants. And some of those new variants will just disappear,” Whitty told a press conference. “But some of them will cause significant problems.”
