On Twitter someone floated the idea that human DNA in vaccines might have something to do with it. A boy gets a vaccine that has DNA in it from an aborted female baby. I don't know if it's true or not but it's something to look into. I have heard that human DNA in vaccines can cause autoimmune disorders.
As far as latex and peanut allergies…vaccines often contain latex and/or peanut oil. So that's likely why there's such an issue lately with peanut allergies.
