How do you explain covid spreading like wildfire in China when the zero covid lockdown was lifted and from what I saw at the time mask wearing seemed like it was at 100%. The virus is very, very small i.e. aerosolized and will spread. Apart from this it's a virus that everyone will be exposed to. Jabs, masks doesn't matter. It's related to part of the common cold family of viruses and will be around for decades to come.
