“Thanks to combination vaccines, your child can get protection from many different diseases with one injection (shot). Examples include MMR (measles, mumps, rubella) and the 5-in-1 vaccine (diphtheria, tetanus, pertussis, polio, Hib disease). Studies show that combination vaccines are safe and effective. There is no reason for your child to get the vaccines one at a time. Getting more than one vaccine at once also means no delay in protection, fewer medical visits and fewer needles (which can be less traumatic).”
