ActHIB (haemophilus b conjugate vaccine) is an immunization used to prevent infection caused by haemophilus B bacteria, and is sometimes combined with vaccines to protect against other diseases. ActHIB vaccine will not protect against other types of influenza. Common side effects of ActHIB include
- injection site reactions (redness, pain, swelling, or a lump)
- low fever
- mild fussiness or crying
- joint pain
- body aches
- drowsiness, or
The number of doses of ActHIB Vaccine indicated depends on the age at which immunization is begun. A child 7 to 11 months of age should receive 2 doses of ActHIB Vaccine at 8-week intervals and a booster dose at 15 to 18 months of age. A child 12 to 14 months of age should receive 1 dose of ActHIB Vaccine followed by a booster 2 months later. Consult your doctor for the immunization schedule. ActHIB may interact with steroids, medications to treat psoriasis, rheumatoid arthritis, or other autoimmune disorders, or medicines to treat or prevent organ transplant rejection. Tell your doctor all medications and supplements you use, and all vaccines you have recently received. Before you receive the ActHIB vaccine, tell your doctor if you are pregnant. This vaccine should not be given to a woman who is breastfeeding.
Our ActHIB (haemophilus b conjugate vaccine) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Keep track of any and all side effects your child has after receiving this vaccine. When the child receives another haemophilus B vaccine in the future, you will need to tell the child's doctor if the first shot caused any side effects.
Becoming infected with haemophilus B is much more dangerous to your child's health than receiving the vaccine to protect against it. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.
Get emergency medical help if your child has any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if your child has any of these serious side effects:
- extreme drowsiness, fainting;
- fussiness, irritability, crying for an hour or longer;
- seizure (black-out or convulsions); or
- high fever (within a few hours or a few days after the vaccine).
Less serious side effects may include:
- redness, pain, swelling, or a lump where the shot was given;
- low fever;
- mild fussiness or crying;
- joint pain, body aches;
- drowsiness; or

More than 7,000 infants and young children ( ≤ 2 years of age) have received at least one dose of ActHIB vaccine during US clinical trials. Of these, 1,064 subjects 12 to 24 months of age who received ActHIB vaccine alone reported no serious or life threatening adverse reactions.
Adverse reactions commonly associated with a first ActHIB vaccine immunization of children 12 to 15 months of age who were previously unimmunized with any Haemophilus b conjugate vaccine, include local pain, redness, and swelling at the injection site. Systemic reactions include fever, irritability, and lethargy.4,10
Adverse reactions associated with ActHIB vaccine generally subsided after 24 hours and usually do not persist beyond 48 hours after immunization.
In a US trial, safety of TriHIBit vaccine, ActHIB vaccine combined with Tripedia vaccine by reconstitution, in 110 children aged 15 to 20 months was compared to ActHIB vaccine given with Tripedia vaccine at separate sites to 110 children. All children received three doses of Haemophilus b conjugate vaccine (ActHIB vaccine or HibTITER) and three doses of whole-cell DTP at approximately 2, 4, and 6 months of age.

TriHIBit vaccine, ActHIB vaccine combined with Tripedia vaccine by reconstitution, was administered to approximately 850 children, aged 15 to 20 months. All children received three doses of a Haemophilus b conjugate vaccine (ActHIB vaccine or HibTITER) and three doses of whole-cell DTP at approximately 2, 4, and 6 months of age. Local reactions were typically mild and usually resolved within the 24 to 48 hour period after immunization. The most common local reactions were pain and tenderness at the injection site. Systemic reactions occurring were usually mild and resolved within 72 hours of immunization. The reaction rates were similar to those observed in TABLE 5 when TriHIBit vaccine, ActHIB vaccine reconstituted with Tripedia vaccine, was administered and when Tripedia vaccine was administered alone as a booster.10
The number of subjects studied with TriHIBit vaccine, ActHIB vaccine combined with Tripedia vaccine by reconstitution, was inadequate to detect rare serious adverse events.
Reporting of Adverse Events
Reporting by the parent or guardian of all adverse events occurring after vaccine administration should be encouraged. Adverse events following immunization with vaccine should be reported by the health-care provider to the US Department of Health and Human Services (DHHS) Vaccine Adverse Event Reporting System (VAERS). Reporting forms and information about reporting requirements or completion of the form can be obtained from VAERS through a tollfree number 1-800-822-7967.15,16,18
Health-care providers also should report these events to Sanofi Pasteur Inc., Discovery Drive, Swiftwater, PA 18370 or call 1-800-822-2463.
The following events have been spontaneously reported during the post-approval use of ActHIB. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.
- Immune System Disorders: Anaphylaxis, other allergic/hypersensitivity reactions (including urticaria, angioedema)
- Nervous System Disorders: Convulsions
- General Disorders and Administration Site Conditions: Extensive limb swelling, peripheral edema, pruritus, and rash
