Masks in surgical environments are to prevent bacterial infection & bodily fluid transfer and there is scientific debate on whether they even do that SINGLE USE surgical masks in hospitals are used once. In public they are used when dirty with bacteria and other debris. Masks in medical settings that prevent viral infections are professionally fitted and are not removed in the environment that they are used.
If masks worked then there would be no need for the “vaccine,” if the “vaccine” worked there would be no need for masks.
If wearing a mask makes you feel safe & virtuous then carry on, also booster 4,5,6 etc is on the way because “it would be worse if you didn’t take an experimental injection”.
