Tresivac Description

The vaccine is prepared from the live, attenuated strains of Edmonston-Zagreb measles virus, Leningrad-Zagreb (L-Z) mumps virus and Wistar RA 27/3 rubella virus. The measles and rubella viruses are propagated on human diploid cells (HDC) and the mumps virus is grown on chick fibroblasts from SPF eggs (Specific pathogen free eggs). The vaccine is freeze-dried and is provided with diluent. The product has the appearance of yellowish-white dry cake. The vaccine meets the requirements of W.H.O. when tested by the methods outlined in W.H.O., TRS 840 (1994).
Potency: Each single human dose when reconstituted in a volume of 0.5 mL contains not less than 1000 CCID₅₀ of measles virus, 5000 CCID₅₀ of mumps virus and 1000 CCID₅₀ of Rubella virus. In addition, the freeze-dried vaccine when stored at 37°C for 7 days shows no loss in potency (less than 1.0 log₁₀ loss in virus titres).
