Haemophilus influenzae bacteria — type b (Hib) among them — can cause serious illness and death in babies and children under 5. Hib vaccines are the best protection against serious Hib infection, and CDC recommends them for every child in the United States under 5. Side effects are uncommon.
Who should get it
Children under 5
Young children need several doses:
| Age | Dose |
|---|---|
| 2 months | first |
| 4 months | second |
| 6 months | only for some brands |
| 12 through 15 months | the last |
Older children and adults
Usually they do not need a Hib vaccine. CDC recommends it for just two groups:
- unvaccinated people with certain medical conditions;
- people who have had a bone marrow transplant.
When to hold off
Talk to a vaccine provider about your vaccination history and the ingredients of a particular vaccine. Someone may need to skip a Hib vaccine if they:
- are younger than 6 weeks;
- had a life-threatening allergic reaction after a previous Hib vaccine;
- have a severe allergy to any ingredient.
A mild illness such as a cold is generally not a reason to wait; the provider can advise.
How well it works
Hib vaccines work well, but no vaccine prevents every case. CDC's page on how well Hib vaccines work has the details.
Side effects
Most people have no problems. As with any medicine, side effects are possible — usually mild and gone within a few days, though serious reactions can happen.
Mild reactions are uncommon. When they occur they usually start soon after the shot and last up to 2 or 3 days:
- redness, warmth or swelling where the shot was given;
- fever.

Where to get it
| For | Where |
|---|---|
| Children | Hib is part of the routine childhood schedule, so at least one Hib vaccine is regularly stocked at pediatric and family practices, community health clinics and public health departments |
| Adults | usually a health care provider's office or a pharmacy; if your provider does not have it, ask for a referral |
| No regular source of care | a federally funded health center, or your health department |
Paying for it
- Private insurance: most plans cover it; check costs and in-network providers with your insurer.
- Vaccines for Children: provides vaccines for children whose parents or guardians may not be able to afford them.
