Drug InteractionsHuman antibody products
To avoid inactivating vaccine, give MMR 2 to 4 wk before or 3 to 11 mo after AGIV, depending on dose. Susceptible postpartum women who received blood products or Rho(D) immune globulin may receive rubella vaccine prior to discharge, provided that rubella titer is measured 6 to 8 wk after vaccination to ensure seroconversion.Immunosuppressants, interferon, meningococcal vaccine
May inhibit response to MMR vaccine.
Laboratory Test Interactions
