The overload on the immune system is a myth. Plus, any reasonable instructions say not to give someone a vaccine when the adult or child is also sick with something else. I just don’t understand why be against so many.
Frankly, I don’t believe your assertion of the “myth” theory. I’ve personally seen three instances of those kinds of shots causing severe problems with children - two of them basically converted them to vegetables.
I also personally have experienced very adverse affects for years from the 70s era Swine Flu vaccine where I got pleurisy. It took more than a decade to begin feeling normal from that one shot.
My point is that there isn’t a valid reason to do all this multiple stuff in one dose, EXCEPT for time, trouble and money, period. What is the harm in spacing them out?
Medicine is mainly a trial, error, and experience situation in my opinion. The head of our CDC was telling people to just “wash your hands” when the recent Ebola scare hit. He was forced to admit his “protocol” was limited by Sanjay Gupta, IIRC.
You can take that chance with your children - I won’t.
