The Hib shot, or Haemophilus influenzae type b (Hib) vaccine, is a vaccine that protects against serious infections caused by the Haemophilus influenzae type b bacteria. This bacteria can cause several infections, including meningitis (inflammation of the brain and spinal cord), pneumonia (infection of the lungs), and epiglottitis (infection of the tissues in the throat). These infections are particularly dangerous for children under five years old, but they can also affect adults with certain medical conditions.
The Hib vaccine is highly effective in preventing Hib disease. It works by stimulating the body's immune system to produce antibodies against the Hib bacteria. The Hib vaccine is typically given to infants in a series of shots starting at two months of age. Most infants will receive their first dose at two months, followed by doses at four months, six months, and between 12 and 15 months of age.
The Hib vaccine is safe and effective. Some common side effects may include mild fever, soreness at the injection site, and fussiness. These side effects typically go away within a few days.
The Hib vaccine is an important part of the childhood immunization schedule and has greatly reduced the number of Hib disease cases in the United States and other countries.
