Are there any side effects from the meningococcal vaccine?
Contracting meningitis or sepsis is very dangerous, much more so than any side effects from the vaccine. Though allergic reactions are possible, the meningococcal vaccine generally only causes mild side effects.
- Up to 50 percent of kids will experience redness, swelling, or warmth near the shot site.
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 he receives a shot, call your doctor right away.
