Part of that article is pulled from Infowars (dead children in school shootings are actually actors faking it) and say it's based on research from the Francis Crick Institute. I'd rather check the source. Guess what vaccines targeting a specific virus don't work as well against variants, pretty basic. Nowhere do the results show the Pfizer vaccine weakens the immune system.
