Vaccines work if you take them.The Pas Swamp Donkey said:Next you'll be arguing that masks don't work either.............
The way ordinary people wear and behave with the masks they wear, they don't work and likely increase the risk. Plot mask use with infections and unlike with the vaccine, you don't see a drop or we would not have a problem. There is a big difference between theoretically and in practice. For many the mask gives a false sense of security, so they take risks they would not without their security blanket. It's supposed to be "wear a mask if you cannot social distance" and not "wear a mask so I don't have to social distance."
In practice masks do little to nothing and maybe make it worse or we would see different results.
Do NOT do anything with a mask you would not do without one.
