Posology: ProQuad should be used in accordance to official recommendations.
Individuals 12 months of age and older: Individuals from 12 months of age should receive two doses of ProQuad or a single dose of ProQuad followed by a second dose of a monovalent varicella vaccine to ensure optimal protection against varicella (see Pharmacology: Pharmacodynamics under Actions). At least one month must elapse between the first and second dose of any live viral attenuated vaccine. It is preferred that the second dose be administered within three months following the first dose.
Individuals between 9 and 12 months of age: Immunogenicity and safety data show that ProQuad can be administered to individuals between 9 and 12 months of age, under special circumstances (e.g., in accordance with official recommendations or when early protection is considered necessary). In such cases, individuals should receive a second dose of ProQuad, given a minimum of 3 months apart, to ensure optimal protection against measles and varicella (see Precautions and Pharmacology: Pharmacodynamics under Actions).
Individuals less than 9 months of age: ProQuad is not indicated in this subset of the paediatric population. The safety and efficacy of ProQuad in children under 9 months of age have not been established.
ProQuad may be used as the second dose in individuals who have previously received measles, mumps, and rubella vaccine and varicella vaccine.
Method of administration: The vaccine is to be injected intramuscularly (IM) or subcutaneously (SC).
The preferred injection sites are the anterolateral area of the thigh in younger children and the deltoid area in older children, adolescents, and adults.
The vaccine should be administered subcutaneously in patients with thrombocytopenia or any coagulation disorder.
