Call for questions: Common reactions after vaccines include mild fussiness, low grade fevers for a day or two, and maybe a mild pink rash. (certain vaccines, like measles or chicken pox, tend to cause their reactions after several days or so.) anything beyond these common signs deserves a call to your child's pediatrician.

Call your doctor: Low grade fever, fussiness, and a little redness at the site are common and cause no long term problems. A high fever of 103 or more, a seizure (very rare, ) screaming inconsolably, difficulty breathing, or the presence of a large, warm, reddened area at the site warrant a call to your doctor.

Vaccine safety: While you can't prevent an adverse reaction to a vaccine, they are very rare. Educate yourself about the vaccines and ask your baby's doctors any questions or concerns. Some babies wil have fussiness, low grade fever or soreness after receiving routine immunizations. If your baby has a high fever or extreme irritability after a vaccine visit, call to discuss with your pediatrician.

Rash, can't breath: An allergic reaction to a vaccine or vaccine component will not be subtle. A rash over most of your body, swelling (severe) at the injection site, and aches plus (possibly) difficulty breathing.
