But would just one dose make it easier for the virus to become resistant? I've been hearing lately that people might need a third booster for full immunity.

And on another note, a couple of my friends who had Covid last month got their shots, but I haven't been able to get on the vaccine schedule. It seems people who have had Covid would have some antibodies and should go to the back of the line because they are immune, at least for a while.

Many of my friends have had it at this point.
