Can Adults Be Vaccinated for Chickenpox?

Ask the experts

I never had chickenpox as a kid. This wasn't a problem until recently. I have a 4-year-old and an 8-year-old in school, and there is currently a spate of chickenpox going through their school. My kids have their immunizations, but should I get one? Can adults be vaccinated for chickenpox?

Doctor's response

Varicella is the virus that causes chickenpox. While the disease is usually self-limited, it can cause death and permanent injury. The groups at greatest risk are infants, people over 15 years of age, and immunocompromised people. The vaccine came out in the mid-1990s and unfortunately does not offer complete protection, but even those who get the disease after vaccination have a milder form of the condition. Prior to use of the vaccine, hundreds of children died every year from chickenpox. It is recommended that all adolescents and adults without documented evidence of chickenpox or previous vaccination receive the two-dose series.

Vaccine-preventable diseases are those diseases for which there is a shot that helps the immune system prepare for an infection. A person develops immunity after he or she has received a vaccine and responded to it. When a vaccinated person is exposed to a virus (for example, hepatitis B) or bacteria (for example, diphtheria), his or her body is able to destroy the virus or bacteria and prevent the disease. No vaccine is perfect, and some people who receive a vaccine can still get the disease. This is why it is important for everyone to get the vaccine. This gives the community what experts call "herd" immunity and means that, basically, there are very few people who could serve as a reservoir for the disease. Herd immunity prevents severe outbreaks of diseases.
