getting immunization less than a month apart will hurt my children heath?

my question is my daughter got her shots hepb at #1 birth #2 at two months #3 at 3months #4 at 15 months is this ok? I also noticed that all of her shots where like that. My son's shot are about the same. Should I this be something that I need to bring up to my children doctor? Thank you

If you follow your doctor's protocol, by the end of one year your infant will have been immunized against 64 different ailments (shots are combined so the total is not obvious). If you think this assault on a young immune system is wise (which apparently you do not) then go ahead. Many think such a regimen is extremely harmful. I am one of those people. Does it cause autism. I don't know. Many think it does.
