The current varicella vaccine contains live attenuated virus and is 97% effective against moderately severe and severe disease and 44�85% protective against any infection for at least 7 years. When the disease does develop in vaccinees, it is usually mild, producing fewer than 30 pox lesions. Due to break-through cases, a second dose of varicella is now recommended for all age groups.
