ProQuad – Mumps, rubella and varicella (live) uses, dose and side effects


Powder and solvent for suspension for injection
mumps, rubella and varicella (live).

What ProQuad is and what it is used for

ProQuad is a vaccine containing measles, mumps, rubella, and varicella viruses that have been weakened. When the vaccine is given to a person, the immune system (the body’s natural defense system) will produce antibodies against measles, mumps, rubella, and varicella viruses. The antibodies help protect against diseases caused by these viruses.

ProQuad is given to your child to protect against measles, mumps, rubella, and chickenpox (varicella). The vaccine can be given to people from 12 months of age.

ProQuad can also be given to children from 9 months of age under special conditions (eg to follow national vaccination schedules, outbreak situations, or travel to an area with a high incidence of measles).

Although ProQuad contains live viruses, they are too weak to cause measles, mumps, rubella, or varicella in healthy people.

What you need to know before you get ProQuad

Do not use ProQuad

  • if the person to be vaccinated is allergic to any varicella vaccine or measles, mumps, rubella vaccine, or any of the ingredients of this vaccine (listed in section 6) including neomycin.
  • if the person to be vaccinated has a blood disease or some type of cancer that affects the immune system.
  • if the person to be vaccinated is receiving treatment or taking any medication that may weaken the immune system (except low-dose corticosteroid therapy for asthma or replacement therapy).
  • if the person to be vaccinated has a weakened immune system due to illness (including AIDS ).
  • if the person is to be vaccinated or the family has a congenital or hereditary immune deficiency if it has not been shown that this person has an adequate immune system.
  • if the person to be vaccinated has active untreated tuberculosis.
  • if the person to be vaccinated has a disease with a fever exceeding 38.5 ° C; However, low-grade fever alone is not a reason to postpone vaccination.
  • if the person to be vaccinated is pregnant (pregnancy should also be avoided 1 month after vaccination, see Pregnancy and breastfeeding).

Warnings and cautions

If the person to be vaccinated has experienced any of the following, talk to your doctor or pharmacist before giving ProQuad:

  • An allergic reaction to eggs or to anything that contained eggs.
  • Have had allergies or seizures, or if anyone in the family has had this.
  • A side effect after vaccination with a vaccine containing measles, mumps, and/or rubella in the form of bruising or longer bleeding time than normal.
  • An HIV infection without showing symptoms of HIV disease. Vaccination may then be less effective than for non-infected people (see Do not use ProQuad ).

If you suffer from a coagulation disorder or low platelet count, the injection will occur and will be given under the skin.

In rare cases, it is possible to get chickenpox, including severe chickenpox, from a person who has been vaccinated with ProQuad. This can occur in people who have not previously been vaccinated against chickenpox or had chickenpox, as well as in people who fall into one of the following categories:

  • individuals with reduced disease resistance.
  • pregnant women who have not had chickenpox or who have not been vaccinated against chickenpox.
  • newborns whose mothers have not had chickenpox or who have not been vaccinated against chickenpox.

If possible, individuals vaccinated with ProQuad should try to avoid close contact, for up to 6 weeks after vaccination, with anyone who falls into one of the categories above. Tell your doctor if there is anyone who falls into one of these categories and is expected to come into close contact with the person who has been vaccinated.

As with other vaccines, ProQuad may not provide complete protection for all people who have been vaccinated. In addition, if the person to be vaccinated has already been exposed to measles, mumps, rubella, or varicella viruses, without having already become ill, ProQuad may not be able to prevent the disease from breaking out.

Other drugs and ProQuad

Tell your doctor or pharmacist if the person to be vaccinated is taking or has recently taken any other medicines (or other vaccines).

ProQuad can be given at the same time as other childhood vaccines such as Prevenar and/or hepatitis A vaccine, or vaccines containing diphtheria, tetanus, acellular pertussis, Haemophilus influenzae type b, inactivated poliomyelitis or hepatitis B. Different injection sites will be used for each vaccine.

Your doctor may postpone vaccination for at least 3 months after a blood or plasma transfusion or administration of immunoglobulin (IG), or varicella-zoster immunoglobulin (VZIG). After vaccination with ProQuad, IG or VZIG should not be given until after 1 month, unless your doctor tells you otherwise.

If a tuberculin test is to be performed, it should be done either before, at the same time as, or 4 to 6 weeks after vaccination with ProQuad.

Tell your doctor if the person to be vaccinated has recently been vaccinated or will be vaccinated shortly. Your doctor will decide when ProQuad should be given.

The use of salicylates (eg acetylsalicylic acid, a substance used in many painkillers and antipyretics) should be avoided for 6 weeks after vaccination with ProQuad.

Pregnancy and breastfeeding

ProQuad should not be given to pregnant women. Women of childbearing potential should take the necessary precautions to avoid pregnancy for 1 month after vaccination.

Women who are breastfeeding or intending to breastfeed should tell their doctor. Your doctor will decide if ProQuad should be used.

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this vaccine.

ProQuad should not be injected directly into a blood vessel.

ProQuad is given by injection as follows:

  • Children between 9 and 12 months of age: ProQuad can be given from 9 months of age. To ensure optimal protection against chickenpox and measles, two doses of ProQuad should be given at least three months apart.
