Re: Media seem to have gone quiet over vaccine tweaks over recent months
Of course there is the South African (not sure about its official name) variant that I believe did show vaccine evasion ability. Obviously its been out-competed by Delta's massive transmissibility advantage. Maybe the virus shot itself in the foot there? If vaccines work too well then maybe Delta will mutate to compensate, but as has been mentioned before, evolutionary pressures often involve a trade-off. So Delta could get round vaccines better but lose on transmission.
