Read the vaccine inserts and the book turtles all the way down (not the novel) to make an informed decision
Would recommend Children’s Health Defense as a great resource for vaccine info. They have a lot of documentaries and compilations of research that look into vaccine ingredients and side effects. Also, Weston A Price Foundation, slightly different focus as it primarily looks at nutrition but they have some great info on toxins in vaccines https://www.westonaprice.org/health-topics-category/vaccinations/#gsc.tab=0
I Moore thinking of polio and measles vaccine
