Infection results in lifelong immunity. Approximately 95% of women born in the United States have VZV antibodies by the time they reach reproductive age. The incidence of VZV infection during pregnancy has been reported as up to 7:10,000. The vaccine is contraindicated in pregnancy because the effects of the vaccine on the fetus are unknown. Nonpregnant women who are vaccinated should avoid pregnancy for 1 month after injection. Inadvertent vaccination in early pregnancy or within a month of pregnancy is not an indication for termination, although women should be counseled about theoretical risks.
