1) No vaccine in the history of vaccines has been 100% safe. Not one. NO one ever promised you that. Well, no one who even has a passing knowledge of vaccines. I'm sure that the anti-vaxx echo chamber has claimed that Fauci said it was 100% safe.
2) No vaccine in the history of vaccines has not had side effects for some portion of the population. No one promised you that it was 100% side-effect free. Oh, I'm sure the anti-vaxx crowd has claimed that someone said it was 100% side-effect free. But it, like all the other vaccines, isn't. All vaccines have side effects. Some of them are even lethal (see small pox vaccine).
3) No vaccine in the history of vaccines has been 100% effective. Not one. In fact, the one you're probably thinking of now is the Small Pox vaccine. The one that wiped out small pox. It's only 87% effective. So how did it wipe out a disease? Literally everyone who could get it, got it. Also, it's one of the most dangerous ones. And claiming that we shouldn't be using a vaccine until it's 100% effective is asinine. You may not remember it, but the efficacy rating of the covid vaccine was discussed. And how the different manufacturers had different ratings, because some were more or less effective than others.
No one said they were 100% effective. Well, again, I am sure the anti-vaxx crowd has claimed that, but that is a lie.
And apparently you do need a scientist because you don't know how vaccines work.
Science didn't lie to you. The anti-vaxx crowd has certainly lied to you. Lied to you about what science has said about vaccines, and specifically about the covid vaccines.
And while your personal experience with previous vaccines has led you to believe that they're 100% effective, it's simply not true. The appear 100% effective when close to 100% of the population gets them.
When we're all 87+% resistant to a disease, the occasional breakthrough infection doesn't spread any further. And it doesn't have a chance to mutate. (again, no one claimed it wouldn't mutate). And when it doesn't mutate, the existing vaccine doesn't need to be updated.
And eventually, the disease is wiped out.
