the chickenpox vaccine first became available in 1995. i'm not sure when you received your childhood vaccines but it is likely that the vaccine was not available during that time. talk to your doctor to see if you qualify as a "susceptible adult" and would benefit from receiving a vaccine against chickenpox. you might first be assessed for immunity and if you did not show immunity you could be vaccinated if your doctor recommends it. even if you have had chickenpox there is no significant risk to receiving a second vaccine.
i never had chicken pox and am taking care of my mother who has shingles. should i be vaccinated?
