well it's not like you can study long term effect by virtue of having a very large large short term datasets, no matter how much large the current dataset is.
My comment was in regard to vaccine safety/side effects, not long-term efficacy.
Flu vaccines are only really effective for a single season. Hopefully it’s longer, but even if c19 vaccines give you only 1-2 years protection before requiring a booster, I’d say that’s still pretty good.
