Answer

A live attenuated varicella vaccine (Oka strain) was approved by the US Food and Drug Administration in 1995 for prophylactic use in healthy children and adults. Vaccination recommendations consist of 1 dose for healthy children aged 12-18 months and 2 doses, in a 4- to 8-week interval, in susceptible persons older than 13 years. Studies in Japan point to high seroconversion rates and long-term immunity in children after vaccination. [22, 23, 24, 25, 26, 32] The need for revaccination, or a booster immunization, will be addressed after more long-term studies have been completed.
