Yes, protection from the virus from vaccination or natural immunity does fall off, at least thus far. That is the reason for the second shot and the booster. In a few months we will know if the booster is enough or if another booster is needed. Remember COVID is a new virus. While it can be confirmed the vaccine is safe and effective, we don't know how long adequate protection lasts. We don't know how long adequate immunity will last from natural immunity either.

Well considering that the vaccine ONLY teaches your immune system to react to the spike protein portion of covid19 and that people who've recovered from covid19 have immune responses to ALL parts of the coronavirus their immunity is greater due to the delta variant being mostly a change in the spike proteins allowing it to bypass vaccine easier than people who have an immune response to the entire virus.....
The issue with natural immunity is about how long it remains effective and all cases of COVID do not produce the same level of natural immunity. That's the reasons it is recommended to vaccinated even if you have had COVID https://www.who.int/publications/i/i...mmunity-2021.1
