Check your child’s immunization records to make sure he or she is up to date on Haemophilus influenzae type b (Hib) shots. The vaccine is given to babies in multiple doses by age 6 months, with a booster shot between 12 and 15 months. But in 2007 the Hib vaccine supply dropped, so the Centers for Disease Control and Prevention and the Advisory Committee on Immunization Practices recommended that only kids with health problems and those not previously vaccinated get the booster. Thankfully, supplies are back up and all children can receive their booster shots. Ask your pediatrician if your child is up to date on the vaccine. Hib can cause serious infections including meningitis and pneumonia.
