Maybe it has someting to do wiht people seeing the jabs don't actually stop you from getting it, and if you do it is like a cold or flu to most people.
An actual vaccine keeps you from getting the disease again without needing endless "boosters". I'm a "Boomer" and was vaccinated against smallpox and polio with real vaccines...no "boosters" involved. For COVID, I took the Pfizer vaccine and the first two "boosters", but when I was told I needed two more "boosters", I decided "three tries and I am out".
