That’s actually incorrect. No vaccine is ever 100.00% effective. Most vaccines just give you anywhere from a 50-95% chance to avoid the disease.
Proof?
Polio is around 99%, but most aren’t that high. In most cases a vaccine is NEVER. I mean never 100%.

The purpose of vaccinations are not 100%. It’s to save lives and get enough people immune to slow or stop a disease from spreading because large amounts of people are immune. 100% would be great. Most are 60-90% effective depending on the disease.
Do your own research. As far as I know, no vaccine has ever been 100% effective. Although, polio is pretty darn close.
And the flu shot is definitely a vaccine. The flu mutates so much, that no vaccine can ever really stop it. Well none with our current technology & medical understanding. The point of it is to reduce your chance of getting it. This is really only important for older / immune compromised people. However, I’ve seen a perfectly healthy 49 year old die from the flu.
I get one every year. If I can avoid the flu, I’ll gladly do it.
I do agree with you on the COVID vaccine. They were rushed and some of them have killed old / compromised people.
