doesn't the vaccine give you covid? Like pretty sure when we all got the shot the first time we all got sick from it. I'm not anti vax and got mine...but still makes me wonder was the vax or covid the reason for the cognitive problems...

No. The COVID vaccine isn’t an inactive vaccine (killed virus) or live attenuated (weakened but live virus) vaccine, it’s an mRNA vaccine. They teach the body to make proteins to trigger an immune response the second they catch that virus in the body.

For all we know, the immune response may cause the damage.

If that were true, then we'd only be seeing this protein result in vaccinated people. The study included both vaccinated and unvaccinated people.
