The Hib Vaccine: Health 101

Are there any side effects from the Hib vaccine?

Contracting Hib disease is far more dangerous than any side effects from the vaccine. Though allergic reactions are possible, the Hib vaccine in particular is known for causing only mild side effects.

• Up to 25 percent of kids will experience redness, swelling, or warmth near the shot site.
• Up to 5 percent of kids will experience fever over 101 F., taken rectally.

As with any vaccine, severe allergic reactions are rare, but possible. If you notice your child having difficulty breathing, hoarseness or wheezing, hives, paleness, weakness, dizziness, or a rapid heartbeat shortly after receiving a shot, call your doctor right away.
