For vaccines in general, yes. But kooky people that think this is some kind of trick are worried about it being an mRNA vaccine, which is indeed somewhat new. The idea has been around for about fifty years, but the first human clinical trials were only about a decade ago and COVID was the first large-scale human deployment.
Now, in fairness, they were almost entirely ready at the time. I would imagine, without COVID, we probably would’ve still seen mRNA vaccines become mainstream already, though maybe last year or this year instead of in 2021. But COVID stepped up the final stages of approval significantly.
Or, y’know, literal decades (centuries?) by medical professionals

I was referring to the usage of masks
Oh! Yes.
