Should children who recover from invasive Hib disease be vaccinated?

Hib invasive disease does not always result in development of protective antibody levels. Children younger than 24 months of age who develop invasive Hib disease should be considered susceptible and should receive Hib vaccine. Vaccination of these children should start as soon as possible during the convalescent phase of the illness. A complete series as recommended for the child’s age should be administered.
