There are plenty of reputable sources on the internet which are up to date which say exactly the same thing about the value of getting a covid booster, especially for older people. As I've already agreed, immunocompromised individuals are special cases, and they are encouraged to seek their doctor's advice before having either a booster, or an extra covid vaccination or not. The booster vaccinations factor in new variants as far as possible. No one has disagreed about the efficacy of the protection waning over a period of time. That's why there are boosters, so I don't see your point at all. Finally, if you want some up to date info, how about the government statistics which show covid related illnesses to be at base levels, and hospitalizations have been generally at a low and decreasing level from July 2024 to April 2025. This seems to fly in face of the idea that boosters lead to people being more susceptible to covid infection.
