Couple of thoughts on the idea of skipping the booster shot because a mask will still be required until "they" can "get it right" --
Why would you expect a huge, complicated, dangerous problem like Covid to have a single solution?
When driving, you wear a seat belt and look for traffic before a left turn, right?
If you want to lose weight, you diet and get exercise.
To improve your budget, you might work more and spend less and invest more wisely and ask for a raise and not give your credit card to your sketchy brother-in-law. You wouldn't do just one thing and demand that it make you rich.
We talk about "belt and suspenders" approaches to lots of problems. This is probably the worst problem to hit us in decades. Why insist on an (even more) easy and simple fix?
Each of the recommended steps (vaccine, masking, distancing, etc.), taken alone, gives less than 100% protection, so overlapping them just makes sense. When you take into account the need to protect not only yourself but also others (for example, if you're contagious but don't know it because you have no symptoms), it makes even more sense.
And btw, "they" are "getting it right." This is how fighting epidemics works -- one step at a time, with changes to advice as the disease evolves and as scientists learn more about it (and as people behave how people behave, which affects how the disease behaves).
