Making measles great again!
The evidence is that the vaccines prevent infection while you have active antibodies. At least as well as the measles vaccine does. The difference is when antibodies Wane protection wanes because the incubation period for covid is 3 days. That's too short for memory cells to fully prevent infections
What do you want them to change about the vaccines?
And the vaccines reduce the rate of long covid as well. No vaccine is perfectly protective and we shouldn't expect them to be.
None of them are 100% preventative.
the covid vaccines prevent a significant percentage of infections.
the covid vaccines don't cause any of those symptoms
No vaccine 100% prevents transmission. The covid vaccines reduce it a lot for more than the length of seasonal waves.
They're already nuts
Vaccines are protective, who knew?
