What is the ProQuad vaccine?
ProQuad is a combination vaccine that protects against measles, mumps, rubella (MMR) and varicella (chickenpox). It’s used for children who need immunization against all four diseases. [1]
Who is ProQuad for, and how is it given?
ProQuad is given to children according to the routine childhood schedule. The doses are given as injections by a healthcare professional. [1]
What diseases does ProQuad prevent?
By combining MMR and varicella, ProQuad helps prevent:
- Measles
- Mumps
- Rubella
- Varicella (chickenpox) [1]
What side effects do people report with ProQuad?
Common side effects can include injection-site reactions and fever. Some children may also develop mild rash or symptoms consistent with a mild vaccine reaction after vaccination (exact frequencies depend on the study and patient factors). [1]
Who should not get ProQuad, or who needs extra caution?
People with certain conditions (for example, severe immunocompromise) or who have had specific prior vaccine reactions may not be appropriate candidates. Clinicians also need to consider pregnancy status and other health conditions when deciding on vaccination. [1]
How does ProQuad compare with giving MMR and varicella as separate shots?
ProQuad combines MMR and varicella into one injection instead of separate vaccines. That can simplify the number of injections while providing the same covered protection against measles, mumps, rubella, and chickenpox. [1]
Where can I find the official prescribing information?
The prescribing information includes details on indications, dosing, administration, contraindications, and adverse reactions. [1]
