I'm not a mask-denier. In varying degrees they are effective against the water vapor droplets carrying viruses. However, home-made cloth masks, neck gaiters, and bandanas are almost worthless, even against water vapor droplets.
Three in my family have immunity from Covid due to having recovered; two, and soon three, also have immunity from being vaccinated. Despite our immunity, we are urged by the Feds and required by the State of California to wear masks. I have a HUGE question whose answer I suspect I already know:
Where is the data that demonstrates that any kind of mask reduces Covid risk better that recovery immunity or vaccination immunity?!
