The recommended dosage of ProQuad is the same for every child. The treatment regimen consists of two doses, with the first one given at age 12 to 15 months and the second dose given before the child starts elementary school (age 4 to 6 years old). If your child is moderately or severely ill, you should probably postpone the injection.
There is only one standard dosage for ProQuad® (MMRV), regardless of your child's age or weight. You should not delay your child's vaccines without first discussing it with your healthcare provider.
The standard ProQuad dosing schedule consists of two doses. The first is given at 12 to 15 months of age, and the second is given just before starting elementary school (age 4 to 6 years old).
ProQuad contains the measles, mumps, and rubella (MMR) vaccine combined with a chickenpox vaccine. For the first dose of this vaccine (in children age 12 to 23 months of age), fevers and febrile seizures (seizures associated with high fevers in young children) are more likely to occur, compared to giving the MMR and chickenpox vaccines separately, as separate injections at the same visit.
Therefore, healthcare providers generally prefer to give the two individual vaccines as separate injections for the first dose. ProQuad can then be used for the second dose, if desired.
Some considerations to keep in mind with ProQuad include the following:
- As with other live vaccines, ProQuad is injected subcutaneously (just under the skin), preferably on the upper arm.
- Children can be vaccinated if they have a minor illness, such as the common cold. However, the vaccine should be postponed if the individual is moderately or severely ill.
- If you are unsure about anything related to ProQuad dosing, please talk with your healthcare provider, nurse, or pharmacist.
