Pretty sure that 66% is an overall number (down from opening line of 95) that includes a combined score for covid (A) and also Delta... but with regard to just Delta the efficacy is something like 44%. So a simple extrapolation suggest they will mandate the flu shot, too... after all, that's about where it's effectiveness is figured (annually).
Can't wait to see how the "vaccines" handle Lamda variant from south america. And whatever follows thereafter.
Out of curiosity, who is paying for all these tests, injections, boosters, etc?
As an aside: why is it spelled "curious" but that U gets dropped when it turns to curiosity? lol.
