Can chickenpox be prevented with a vaccine?
Most people develop lifetime immunity to chickenpox after the first occurrence and never experience it again. But the virus can sometimes resurface later in life as shingles (zoster). The current aim in the U.S. and many other countries is to achieve universal (or nearly universal) immunization of children with the chickenpox vaccine. The vaccination requires only two shots. The first vaccination is given at about 1 year of age, and the second (booster) is given at 4 years of age. If an older person has not had chickenpox, the shot may be given at any time. There have been few significant adverse reactions to the chickenpox vaccine. All children, except those with a compromised immune system, should have the vaccination. Vaccination has been associated with a 90% decrease in the incidence of chickenpox and significantly lower complication rates in those who do develop the symptoms.
- Chickenpox is caused by the varicella-zoster virus which also causes shingles.
- Chickenpox is highly contagious and spreads by contact with someone with chickenpox.
- Fever, malaise, and a rash (red spots, blisters, and crusted lesions) are all symptoms and signs of chickenpox.
- Treatment for chickenpox is basically supportive.
- Although usually self-limited, chickenpox can also cause more serious complications, including pneumonia, encephalitis, and secondary skin infections.
- The chickenpox vaccine has resulted in a decrease in chickenpox incidence by 90% in the United States.
