I don't think a booster shot is a good example, lots of other vaccinations are administered in 3 shots. On others, the current view is that one is enough for life. If there is really a degradation in immune capability, is there any evidence of that from other vaccinations not working as well as in the past? How far the immune system is actually depressed from the lockdowns etc., we will find out. Could also be the other way around, i.e. overreaction. What I have not observed since things are getting back to normal in my part of Europe is that everyone gets a cold etc. as soon as they meet more people.
