We recently discovered that cold medicines were bad for small children. is it possible we will learn the same about vaccines?

Vaccines bad for?: Not a chance in my opinion, I have seen since i graduated from medical school 48 years ago in india and in england enough cases od tetanus, diptheria, whooping cough, measles, mumps, rubella, meningitis, small pox, chicken pox and the list goes on and on.Most of these diseses have been eliminated due to vaccines.Small pox and polio have been wiped out.Vaccines are success story to be written&appreciated.
