Fun fact. None of those things are perfect except staying away from everyone and your entire household doing so as well. Cloth masks work better when both/everyone wears one; that lowers the chance of getting infected to 3%. If only one person wears a mask, there’s a much higher risk of infection. The vaccine and booster are great, but again, not 100%. It is good to stack things in your favor, but stuff still happens. To take the small percentage where people still get sick and use that to decide masks don’t protect anyone at all is ridiculous.
