What problems can occur after chickenpox vaccination?
• Soreness, redness, or swelling where the shot was given is the most common side effect, occurring in about 20% of recipients. • About 1%-4% of vaccine recipients develop a very mild rash or several small bumps following chickenpox vaccination. [NOTE: In very rare instances, it may be possible for someone who gets a rash from the chickenpox vaccine to transmit vaccine virus chickenpox to another person. Persons developing a rash after vaccination should take extra precautions to avoid contact with anyone whose immune system is not working properly. • The vaccine may cause a mild fever 2 weeks after vaccination. • A seizure (jerking and staring spell) usually caused by fever may occur in less than 1 in 1000 vaccine recipients. This may not be related to the vaccine.
