So, I've noticed that some countries and specially in the US people claim to know a lot of people with vaccine side-effects. I'm from Mexico and most people I know are vaccinated and haven't heard anyone with any side-effect, I believe I know a lot of people, let's say about 500 people or more I could hear from, 200 in my larger social circle and about 50 who are very very close to me. Still haven't heard of anyone having a major side effect except the usual fever after getting the shot. Also, let me add that I'm quite observant, and I've actually been actively looking for anyone with side-effects.

Could the vaccine side-effects be targeted to certain populations?

Side note: Most of my closer circle have gotten the vax in the US (Pfizer, Moderna, and Janssen (A LOT of us Janssen, for some reason), but I think the many others took the ones that are available here in Mexico.

Anyway let me know what you think. I'll be looking to answer questions.
