Are there any side effects from the pneumococcal vaccine?
Contracting a pneumococcal disease is far more dangerous than any side effects from the vaccine. Though allergic reactions are possible, the pneumococcal vaccine causes only mild side effects.
- Up to about 33 percent of kids will experience fever over 100.4 F., taken rectally. (Up to two percent will have fever over 102.2 F.)
- Up to 25 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.
