I remeber that time too. In fact, vaccines slowed spread and also made symptoms easier on those who caught it anyway.
And that is exactly what was promissed to me.
You are just full of it, that is it.

Do you see how this absolutely requires not just a lowered infection rate with lowered severity of infection? You need a less than ~10% chance of infection in the vaccinated/otherwise immune for the math to work. If the chances of infection after vaccination are still 80% then there is still a large reservoir of potential carriers and you don't have herd immunity.
For most of history what people expected out of a vaccine was immunity from infection not still getting infected but with less severity.
Herd immunity means the disease wont cause epidemic, if it comes from elsewhere. It does not mean that no single person will get the disease if he encounters it.
Notably, flu vaccine did not stopped flu entirely, is the most common yearly vaccine and I really never seen anyone claim it 100% stops flu.
