The vaccines we’re all designed and created on the orginal strain , my thoughts are this is the issue with how well it works NOW , with delta being the main strain circulating . ( vaccinated can still transmit and die )
Most evidence will point to the Covid virus becoming less deadly , but more transmissible.
Partner that with the horrible fact that so many of the vulnerable died pre vaccination , ( would have died anyway ) like thousands every year die of the flu , but most just have a snotty nose.
AND ………… the data on how effective the vaccines actually are , tell a far better picture than what there actually doing .
Hence I constantly roll back to the September deaths in the uk
