What is Haemophilus influenzae type b (Hib)?

Hib is a bacteria that can cause serious infections in childood such as otitis media (middle ear infection), meningitis, pneumonia, and epiglotitis, a sudden severe swelling above the larynx or voice box.

Serious Hib infections are much less common today than in the past because of good immunization rates with the Hib vaccine.

The symptoms of Hib infection depend on where the infection is located.

What is the Hib vaccine?

The Hib vaccine is given to children to help their immune systems develop a response to the Hib bacteria.

The vaccine against Hib is a man-made version of the capsular sugars  on the surface of the Hib bacteria and is injected into muscle.

If a child is exposed to the bacteria after receiving the vaccine, her immune system will recognize and attack the bacteria.

What are the side effects of the Hib vaccine?

The most common side effects of the Hib vaccine, similar to any  injected vaccine, is pain, irritation, mild redness at the injection  site, and a mild fever. These symptoms may cause prolonged crying.

More severe reactions are exceedingly rare.

It is not possible to become infected with Hib by receiving the vaccine.

Who should NOT receive the Hib vaccine?

Anyone with previous episodes of anaphylaxis immediately following the Hib vaccine.

What is the vaccination schedule for the Hib vaccine?

Newborn dosing schedule:

• Dose #1 at 2 months

• Dose #2 at 4 months

• Dose #3 at 6 months

• Dose #4 between 12-15 months

Children under 5 who have never been vaccinated against Hib should  still receive the vaccinations. Call our office for an appointment.
