Correct. It was/is the lie perpetuated by the far right and propagated by the dying ignorant that the vaccine will prevent you from getting covid. Not a single medical professional or scientist has ever in history said that about vaccines. As you said, vaccines are to educate your immune system to develop and create antibodies to fight off the new diseases as they happen.
Plus the lie that rfk jr and many more anti-vaxxers spread is that the covid vaccines contain strains of covid itself. That's never been true. The only time that was true is back when the concept of vaccines was being established like chicken pox.
