Scientifically speaking, how many shots would we need to not need any more?

First it was 2 shots. Then we need a 3rd and final one to finish it off. After I'm having my 4th shot because my 3rd shot was 6 months ago. Now I'm hearing I need a 5th shot 6 months from now.

How many do I actually need?
