ProQuad (measles mumps rubella varicella vaccine live) may be used in children 12 months through 12 years of age if a second dose of measles, mumps and rubella vaccine is to be administered.
DOSAGE AND ADMINISTRATION
When reconstituted, each vial of ProQuad (measles mumps rubella varicella vaccine live) contains a single 0.5-mL dose. Individuals 12 months through 12 years of age should receive a single 0.5-mL dose of ProQuad (measles mumps rubella varicella vaccine live) administered subcutaneously. At least 1 month should elapse between a dose of a measles-containing vaccine such as M-M-R II, and a dose of ProQuad (measles mumps rubella varicella vaccine live) . If for any reason a second dose of varicella-containing vaccine is required, at least 3 months should elapse between administration of the 2 doses.
CAUTION: Preservatives, antiseptics, detergents, and other anti-viral substances may inactivate the vaccine. Use only sterile syringes that are free of preservatives, antiseptics, detergents and other anti- viral substances for reconstitution and injection of ProQuad (measles mumps rubella varicella vaccine live) .
Withdraw the entire volume of the supplied diluent into a syringe. Use only the diluent supplied with the vaccine since it is free of preservatives or other anti-viral substances.
Inject the entire content of the syringe into the vial containing the powder. Gently agitate to dissolve completely.
Visually inspect the vaccine before and after reconstitution for particulate matter and discoloration prior to administration. Before reconstitution, the lyophilized vaccine is a white to pale yellow compact crystalline plug. ProQuad (measles mumps rubella varicella vaccine live) , when reconstituted, is a clear pale yellow to light pink liquid.
Withdraw the entire amount of the reconstituted vaccine from the vial into the same syringe and inject the entire volume.
TO MINIMIZE LOSS OF POTENCY, THE VACCINE SHOULD BE ADMINISTERED IMMEDIATELY AFTER RECONSTITUTION. DISCARD RECONSTITUTED VACCINE IF IT IS NOT USED WITHIN 30 MINUTES.
Method of Administration
FOR SUBCUTANEOUS ADMINISTRATION
DO NOT INJECT INTRAVASCULARLY
Use a separate sterile syringe and needle for each patient to prevent transmission of infectious agents from one individual to another.
The vaccine is to be injected subcutaneously in the outer aspect of the deltoid region of the upper arm or in the higher anterolateral area of the thigh.
Properly dispose of all needles and syringes. Do not recap needles.
Use With Other Vaccines
