I mean, I know there are pockets of people who believe that saying vaccines don’t work is telling the truth, but broadly speaking, saying that vaccines are fake and don’t work is considered misinformation related to medicine.
But that's not what he's saying, is it?
— Matthew Harrison Brady in Inherit the Wind
We now know of vaccinated people dying of covid, some right after being vaxxed, some months after, some after getting a second dose.
The lyrics can be interpreted a few ways. Was the vaccine then supposed to absolutely stop the spread and give absolute protection to a vaccinated person?
He said vaccines don't work. You also said vaccines don't work. And that's just simply not true.
But they work often enough and to a high enough degree of efficacy that we still should bother.
In specific cases, vaccines may not prevent you from contracting a disease.
In general, vaccines do work. Even if they didn't work in your specific case.
Now, to bring this back around to being on-topic to the thread it's in, whether or not vaccines "work" is actually irrelevant. Either they do work and therefore stop the spread, or they don't work and they therefore don't stop the spread. A vaccine can not work without doing its job.
