Even though vaccines might not be for the newest variant, they do still help because they're the closest to the currently circulating variant (generally speaking). On a biological level I'm not sure how COVID is changing over time but the concept in general is called "Antigenic Drift". So if you want to look more into the concept you might try looking up something like "COVID Antigenic Drift"

Imo it's still a good idea for people with weakened immune systems to continue to get the vaccine even if Antigenic Drift does lower it's efficacy over time.

Thanks for that. I checked out that link and then looked more into it. I didn't know a lot of that but you're right in that it does answer a lot of my questions. I have gotten the updated vaccine shots and I will continue to do so just because, like you said, the weakened immune system and weak lungs aren't a good combination with Covid-19.
