This is absolutely false. No vaccine is 100% effective at providing absolute immunity. Not the MMR. Not Polio. Nobody has claimed otherwise. > Now it's been changed to "provides protection, but ooops that protection can wane over time and eventually disappear". Hmm...just like the annual flu "vaccine", right? And did you forget that other vaccines require boosters, too? Tetanus is an example. It just happens to last several years, rather than several months like a flu or COVID vaccine. Not all antibodies are the same. We now know that COVID-fighting antibodies last a few months. It doesn't mean the vaccines themselves are weak, it means the antibodies our bodies create don't survive long. So yeah, not only are you simply wrong, but you're arguing nothing more than semantics as if it's a valid criticism.

> No vaccine is 100% effective at providing absolute immunity. Not the MMR. Not Polio. Nobody has claimed otherwise. Sure, it's not 100% for those other vaccines, but it's close. Once you get the polio vaccine as a child, you live the rest of your life the exact same way you would if polio were eradicated, without ever having to take any special precautions against the spread of polio again.

The flu vaccine is easily explained by targeting different mutations each year. They also have to choose which mutations they think will be most prevalent before the season starts. Unlike Covid, flu mutations are able to regularly bypass a normal human autoimmune response. I haven’t seen any evidence to suggest that’s true of Covid variants, and have first hand experience with several people infected with early variants who had immunity to later variants. Several years ago there was a flu mutation that was similar enough to a flu from the 1930s (iirc) that people who caught it back then were still immune. It’s not that we need new vaccines for the same virus each year, the virus has just mutated enough that our immune response isn’t trained to identify it. We don’t know how long natural antibodies for Covid last. In my family, members were still immune 9 months after infection and had higher antibody counts than those who were symptomatic. Why is there such a push to convince people that our immune system works differently for this particular virus?

There is no such push. You and others are just misinformed about how the immune system works and, unfortunately, spreading that misinformation--as here.

    How does ephemeral immunity from flu vaccines help the case for Covid vaccines and hurt the case against natural immunity? As mentioned in other comments, however anecdotal, multiple members of my household and extended family have durable immunity 9 months after their infections, without vaccination.
