Priorix is a lyophilized mixed preparation of the attenuated Schwarz measles, RIT 4385 mumps (derived from Jeryl Lynn strain), and Wistar RA 27/3 rubella strains of viruses.
Priorix-TETRA combines measles, mumps, rubella, and varicella vaccine, live, attenuated. It includes a lyophilized mixed preparation of the attenuated Schwarz measles, RIT 4385 mumps (derived from Jeryl Lynn strain), Wistar RA 27/3 rubella, and Oka varicella strains of viruses.
Priorix is indicated to protect against measles, mumps, and rubella. It works by helping the body to make its own antibodies that protect your child against these diseases.
Priorix is administered as a subcutaneous or Intramuscular injection in the deltoid region or in the anterolateral area of the thigh.
A single 0.5 mL dose of the reconstituted vaccine is recommended.
The Canadian Immunization Guide recommends immunization at 12 months of age, or as soon as practicable thereafter.
A second dose of MMR is recommended at least 1 month after the first dose, for the purpose of better measles protection.
Priorix is currently licensed outside the USA in over 100 countries, and it is recommended for use in individuals aged ≥9 months, according to a 1- or 2-dose schedule depending on the country.
