The Hib vaccine is an injection that helps protect children from contracting infections due to Haemophilus influenzae type B (Hib), a bacterium that is capable of causing serious illness and potential death in children under age five.
H. influenzae type B (Hib) is a common organism worldwide; it is found in most healthy individuals in the general population. Small children can pick up the bacteria from people who are not aware that they are carriers. When the bacteria spread to the lungs and bloodstream, serious illness, including pneumonia and meningitis , can result. Another serious disease stemming from this pathogen is epiglottitis , an infection of the epiglottis that cause swelling of the airways and potential death.
Pediatricians and the Centers for Disease Control (CDC) recommend that all infants are vaccinated against Hib disease. In general, the vaccine is considered highly effective, with few side effects. Before the institution of routine infant vaccinations in the United States in the 1990s, Hib was the leading of bacterial meningitis among children younger than five years of age. Nearly 1,000 people in the United States died every year from Hib disease. As of the early 2000s, the disease has largely disappeared due to these vaccinations. In developing countries, however, Hib disease is a major cause of serious disease and death in young children.
The Hib vaccine is given in three or four doses during infancy, depending on the brand used. The first dose starts at about two months of age, and the last is usually scheduled at a 12- or 15-month check-up. Children older than five years do not need vaccination , unless the child or adolescent has a serious health problem that lowers immunity, such as HIV infection , sickle cell disease, or is being treated for cancer .
Infants under six weeks of age should not receive the Hib vaccine. Those babies with moderate to severe illness should wait for vaccination until they are well. If a baby has had a severe reaction to Hib vaccine, another dose should not be administered.
Like any vaccine or medication, Hib vaccine is capable of causing an allergic reaction. However, this is extremely rare. More common side effects include inflammation at the injection site and slight fever , which can usually occur within 24 hours of the injection and can last two or three days.
Interactions with medicines or food have not been reported. The Hib vaccine is routinely given at the same time as other childhood vaccines.
Parents should be aware of the benefits this vaccine provides, as well as its overall safety and effectiveness. Any low-grade fever or soreness can be treated with ibuprofen or acetaminophen as recommended by the pediatrician. Serious reactions, including high fever, difficulty breathing, and fast heartbeat should receive immediate medical treatment.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
