Hib vaccine can prevent Haemophilus influenzae type b (Hib) disease, which is a bacterium that commonly infects children under 5 years of age.
Despite its name, this disease is not the same as influenza (the flu).
How does it spread?
Hib infection is spread by coughing, sneezing, or having close face-to-face contact.
Hib infection can also cause:
a mild illness, such as ear infections or bronchitis
pneumonia
severe swelling in the throat, making it hard to breathe,
infections of the blood, joints, bones, and covering of the heart,
meningitis, an infection of the lining that covers the brain, which can lead to brain damage and deafness.
Other effects: sepsis, otitis media, acute epiglottitis, and even death. Epiglottitis may occur in patients with fever, sore throat, drooling, swallowing pain, refusing to swallow, and even breathing difficulties and other symptoms.
Death
CDC recommends Hib vaccination for all children younger than 5 years old. Hib is also included in some of the mixed vaccines, such as 5 in 1 and 6 in 1 vaccine, as shown in the table.
