Haemophilus influenzae serotype B (Hib) vaccine

Haemophilus influenzae causes epiglottitis, pneumonia and meningitis after colonizing the nasopharynx via droplet transmission. Invasive disease is caused by six capsulated serotypes, of which serotype b is the most virulent. The risk of invasive Haemophilus influenza infection is increased in HIV-infected persons (1), however infection due to the vaccine strain (Hib) is uncommon in settings where vaccine use is widespread (2). Vaccination should be administered in accordance with routine indications, regardless of immune status, HIV viral load and ART.
