The Hib vaccination is given to help protect the body from Haemophilus influenzae type B infections. According to the Centers for Disease Control and Prevention, Hib disease can cause bacterial meningitis, pneumonia, infections of the blood, joints, bones and covering of the heart, and even death. It is recommended in a four-part series beginning at 2 months of age with the final vaccine given at 12 to 15 months of age. There are some side effects associated with the Hib vaccination shot.
Injection Site Reaction
The HIb vaccination may cause an injection site reaction which can last up to several days following vaccination. Redness, warmth or swelling where the shot was given can occur in up to 1/4 of children who receive this immunization, says the CDC. Applying a warm compress to the affected area may help to alleviate swelling and tenderness. Parents of vaccinated children should use caution while bathing, diapering and handling the child so as to not place pressure on the site of injection. A severe site reaction should be brought to the attention of a physician.
Fever
Fever is a possible side effect of the Hib vaccine. According to the CDC, fever over 101 degrees Fahrenheit can occur in up to 1 out of 20 children. Some pediatricians may recommend the use of infant or children's acetaminophen prior to or immediately following vaccination. In some children fever may lead to irritability, fatigue and diminished appetite. Maintaining hydration is important during fever to prevent the development of dehydration. A high fever or a fever that is accompanied by changes in behavior may be a sign of a serious reaction and should be reported to a doctor immediately.
Severe Reaction
Serious problems associated with receiving the Hib immunization are rare and are mainly due to allergic reactions to parts of the vaccine, reports MedlinePlus. Those who have experienced a severe reaction to a Hib vaccine in the past should not receive subsequent doses of the vaccination. Symptoms of a severe reaction can include hives, difficulty breathing, swelling of the tongue or throat and dizziness following vaccination, reports the CDC.
