ATLANTA, June 22 -- Varicella vaccine should be administered in a two-dose regimen with the first dose at 12 to 15 months and the second dose at age four to six.
This latest recommendation from the Advisory Committee on Immunization Practices (ACIP), published in the June 22 issue of Mortality and Morbidity Weekly Report, replaces the earlier standard of a single dose for children who are vaccinated up to age 13 and two doses for those immunized at a later age.
Other ACIP recommendations include:
ACIP also approved criteria for evidence of immunity to varicella.
But the ACIP added a few caveats to these criteria -- commercial assays "lack sensitivity to always detect vaccine-induced immunity (i.e. they may yield false-negative results)" and birth before 1980 should not be considered evidence of immunity for health care workers, pregnant women, and immunocompromised individuals.
