You are correct although I did not check the math. When they began testing everyone and their dog, it was used to push fear and gain control.
I figured it would come back to bite them because their own figures would show herd immunity.
Of course they finally got wise to that, which is why we never hear about those who had covid only vaccination numbers. When we all know the best immunity is that which surviving the virus provides. The idea that those that had covid need to vaccinate is ludicrous.
Oh and I hear upwards of 80% plus needed for herd immunity. That is nonsense, no virus can live on with 80% plus immune. Typical herd immunity is achieved far earlier than 80%.
Anyway, they cannot count those that already had covid because that would put an end to their control.
No more spread of Covid will show we've reached herd immunity, not some mathematical formula.
