South African Covid mutation poses 're-infection risk' which could overpower vaccines, study finds Researchers in S.A. found spike protein mutation was able to 'escape' immunity Virus able to re-infect people, meaning it could also defy vaccine immunity Comes as Sir Patrick said there were 'question marks' over S.A. and Brazil strains He said it was 'quite likely' Britons will be required to have a new jab every year By SAM BLANCHARD DEPUTY HEALTH EDITOR and ROSS IBBETSON FOR MAILONLINE and AFP PUBLISHED: 13:22 GMT, 20 January 2021 | UPDATED: 00:38 GMT, 21 January 2021
Cambridge University microbiologist Dr Ravi Gupta yesterday told MailOnline 'the time has come' to start making updated vaccines to tackle common concerning mutations that have cropped up in multiple unconnected variants around the world.Moderna said it was confident its jab will work against the England and South Africa variants and it will carry out more tests on the Brazilian one. Oxford University said it was running checks on its own jab.Pfizer today said the it was 'unlikely' that the B.1.1.7 lineage — the Kent variant — will evade the vaccine. Studies of a lab-made version of the variant was neutralised by antibodies created by the jab.
When asked about variants and vaccines in a television Q&A on Sky News this morning, Sir Patrick said: 'On the variant that was first identified in Kent, I think we're increasingly of the view that that variant will be susceptible to the vaccine and to previous immunity.
The studies are all pointing in that direction so I think that's good in terms of vaccine effect. 'For some of the others that are popping up around the world – and they will continue to pop up – we've still got some question marks as to how effective a vaccine will be. 'Those studies need to be continued and I think it's likely that we will need to have modified vaccines in due course.'
Companies and scientists making the current crop of vaccines insist that their vaccines will still work as intended, at least on the Kent variant also known as B.1.1.7.
ワクチンはイギリス変異種には効くみたいだが、モデルナを除いて、南ア変異種についてはまだ不明、モデルナもブラジル変異種に効くかどうかまだわからん・・・・みたいだなあ、やっぱ。
