If I remember correctly, CDC said that total immunity would last several months. Then a fully vaccinated person could contract Covid, show no symptoms--but could infect unvaccinated people.
I thought that the CDC sounded uncertain, which is par for the course when it comes to them. It seems the baseball players and Mahar were recently vaccinated, but I am not sure about them being able to spread it. For example, if they have mild symptoms and a cough, cn the cough contain covid germs that another person can catch? The various groups like the World Health Organization all seem uncertain in my opinion. What is more worrisome is the newer strains emerging, and weather or not the vaccine offers any protection from them.
