MUMPSVAX* (Mumps Virus Vaccine Live) is a live virus vaccine for vaccination against mumps.

MUMPSVAX (mumps virus vaccine live) is a sterile lyophilized preparation of the Jeryl Lynn** (B level) strain of mumps virus. The virus was adapted to and propagated in chick embryo cell culture.

The growth medium for mumps is Medium 199 (a buffered salt solution containing vitamins and amino acids and supplemented with fetal bovine serum) containing SPGA (sucrose, phosphate, glutamate, and human albumin) as stabilizer and neomycin.

The cells, virus pools, fetal bovine serum, and human albumin are all screened for the absence of adventitious agents. Human albumin is processed using the Cohn cold ethanol fractionation procedure.

The reconstituted vaccine is for subcutaneous administration. Each 0.5 mL dose contains not less than 20,000 TCID₅₀ (tissue culture infectious doses) of mumps virus. Each dose of the vaccine is calculated to contain sorbitol (14.5 mg), sodium phosphate, sucrose (1.9 mg), sodium chloride, hydrolyzed gelatin (14.5 mg), human albumin (0.3 mg), fetal bovine serum ( < 1 ppm), other buffer and media ingredients and approximately 25 mcg of neomycin. The product contains no preservative.

Before reconstitution, the lyophilized vaccine is a light yellow compact crystalline plug. MUMPSVAX (mumps virus vaccine live) , when reconstituted as directed, is clear yellow.
