We went through exactly what you are going through a few years ago. Right in the middle of Covid clown world time.

Covid really opened our eyes and questions arose so we spent a lot of time agonizing and going over info for all vaccines that were on the schedule.

Some of the very old and traditional ones made sense but more research showed that even those have been modified in recent years and seem sketchy.

In the end none of them made sense to us. We did zero and our almost 3 year old daughter is healthy and doing just fine.

Hope this helps and happy to share some resources if i can dig them up again.

PS you will get a lot of pressure from everywhere on this if you decide against some or all of them.
