Risks
The side effects from the chickenpox vaccine are generally minor. Some of the mild possible side effects include: - Fever
- Pain and swelling in the shot location
- A mild rash
Only in very rare instances have more moderate or severe reactions been reported, including:
- Seizures (less than 1 out of 1,000 children).
- Pneumonia (very rare).
- A true allergic reaction (anaphylaxis), which could cause difficulty breathing, hives, wheezing, fast heart rate, dizziness, and changes in behavior. These can occur anywhere from a few minutes to a few hours after the injection. This is extremely rare.
- Other reactions, such as low blood counts and brain involvement, are so rare that their association with the vaccine is questionable.
