None, of them worked 100%. No “vaccine” ever does. The regular flue vaccines were typically only 50% effective.
However, we all know now that these covid vaccines are different than regular old dead virus vaccines. The MAY leave you more vulnerable after they wear off. Hence, the need for boosters every 6 months.
The problem is each time you take the shot(new or booster) you are playing Russian Roulette. Will this be the time you get inflammation of the heart, Bells Palsy, blood clots or some other things that has yet to be discovered. The issue is we may not know for ten years what these “vaccines” potentially do to the human body.

I posted the math a month ago.
For every life saved by the covid vaxx, at least 45 die as a result of the covid vax.
