It was engineered in a lab to perform a specific function of making your immune system vulnerable to attacks either from prior infections where the host has a prior immunity built, while simultaneously creating a situation where pulmonary and cardiovascular comorbidities are exacerbated; masking the "long" COVID with a shorter, more immediate response in those susceptible. Given the distribution of potential comorbidities in the populace, and the dosaging and controls distributed in the vaccines (tracked by batches and ID #s) they were able to get a decent number of people to play along in their experiment. This was a very sneaky attack, and it took a concert of actors from media, to alt personalities, to the entirety of the medical community (willingly or unwittingly) to pull it off. What's most concerning is that the media dominance by them is still significant enough that the President of the United States wasn't able to come out and simply tell everyone WTAF was going on because the brainwashing was (is?) that deep.
Yeah, the cool thing about the antiparasitics is they work against the vaccine as well.
