Smallpox vaccine did, in fact, prevent infection and transmission with estimated 95% efficiency and is thus considered sterilizing.
The Covid vaccine is very leaky, and Marek’s disease and it’s vaccine in chicken is an interesting comparison.
And I did not claim it was news - all I said was that there is no reason to believe SA is a variant breeding ground (any more than any other place) and explained why.
Yeah I'm wondering what the chances are (something like Marek's disease). To put humanity on a path forever dependent on vaccines. If one shot is enough for life then fine, but two shots per year forever? Scary thought.
