I believe children should be vaccinated it's obvious that they work , I just feel they should be done at different times not all at once ,spacing them apart is how it used to be done,some children might have am immune problem that is not known if there is a way to check for that it could help,my own personal and unpopular opinion is my grandsons autism was caused by his vaccine ,he was doing fine with everything ,when he got the vaccine everything changed almost immediately ,stopped talking ,even the way he ate ,everything he knew and learned was gone,coincidence ? maybe but I don't see how,again this is my opinion
