is the discussion about the new variants
"Madam I have a very large spike protein! do you want to have a look!" does figure - but then says that the spike is so large it is unlikely to escape in one jump ALL the antibodies the vaccine generates.
I dont know if they point out that vaccination wont affect the Bra-heel or Sarf efrican variant because they are already there, but there is a hurry to get it all done to slow further mutation.
it is certainly NOT true to say
oh the virus has changed, so it is not worth having the vacc.
( bearing in mind that this is AB and a lorra free thinking goes on)
