I'm sure you can find some papers easily, I haven't looked into it in years but just from memory there are a few vectors from which problems can arise. The immune system produces antibodies and is responsible for ensuring that they are properly reactive. If this system becomes overactivated, some antibodies may slip through and target the own body, potentially leading to an autoimmune response. We also know that breastfeeding can transfer antibodies from mother to baby. Another consideration is the stability of mRNA production from fetal stem cells. In previous experiments, this process has often been unreliable or unstable. Also the virus mutates much more rapidly than many others, so priming the immune system against a specific variant may reduce its effectiveness against other variants or different viruses.

I'm not talking about people who had a "cure" but about those who shared their experiences openly while being censored and dismissed. People who are not part of a campaign. You assume a lot, and the way you associate everything with anti-vaxxers only shows how much governments have turned this into a political issue. If I say someone close to me had side effects after the vaccine, suddenly I'm assumed to also drink bleach and take dewormers. This is exactly the kind of propaganda they push to discredit anyone who has concerns. At this point, you're basically unable to think critically or discuss the negative. Being part of a herd also comes with some dangerous aspects.
