Hib vaccine. Haemophilus influenzae type B vaccine is a vaccine used to prevent Haemophilus influenzae type b (Hib) infection. In countries that include it as a routine vaccine, rates of severe Hib infections have decreased more than 90%. It has therefore resulted in a decrease in the rate of meningitis, pneumonia, and epiglottitis.
The Hib vaccine is given as an injection into the anterolateral thigh muscle (in infants and toddlers) or in the deltoid muscle of older children. Is there more than one brand of Hib vaccine? There are several formulations of Hib vaccine, includ-ing several that are combined with other vaccines. The number of doses needed depends on the brand of vaccine given. All conjugate Hib vaccines may be given interchange-ably if the original brand is unknown or unavailable. Who should get this vaccine?
