What ProQuad is used for
ProQuad is a vaccine used to help protect people from getting measles, mumps, rubella
(German measles) and chicken pox. It can be given to children aged 12 months to 12
years of age.
Protection against these infections is important as they can cause serious problems
in some people.
Measles is a serious disease that causes a high fever (temperature), runny nose, cough,
conjunctivitis and a rash. It usually lasts for about 1 to 2 weeks. It is very easily
passed from one person to another in the tiny droplets of moisture which are expelled
during coughing or sneezing. One out of every 10 children who catch measles will
also have an ear infection or pneumonia. On rare occasions, measles can also cause
an infection of the brain that could lead to seizures, hearing loss, mental retardation,
and even death. Babies and adults who catch measles are often much sicker for a longer
time or are more likely to die than school children and teenagers who catch measles.
Mumps causes fever, headache, and swollen, painful glands under the jaw (salivary
glands) and usually lasts several days. It is easily passed from one person to another
by the tiny droplets of moisture expelled during coughing or sneezing. Mumps can
sometimes be a very serious disease, causing a mild inflammation of the coverings
of the brain and spinal cord (meningitis) in about one person in every 10 who catch
it. About one out of every 4 teenage or adult males with mumps will have a painful
swelling of the testicles for several days. This does not usually affect their ability
to father children, but can cause sterility in rare cases. Teenagers and adults,
especially males, who catch mumps are often much sicker and more likely to suffer
longer than children do.
Rubella is usually a mild disease that causes a mild fever, swollen glands in the
neck, pain and swelling in the joints, and a rash that lasts for 2 or 3 days. Rubella
is very dangerous if a pregnant woman catches it. Pregnant women who catch rubella
can have babies who are stillborn, or have heart disease, blindness, deafness, or
problems with learning. Rubella is also spread to others in the tiny droplets of
moisture expelled during coughing or sneezing.
Chickenpox (Varicella) is an infectious disease caused by the varicella-zoster virus,
or otherwise known as varicella virus. It occurs in millions of people around the
world each year, most often in children 5 to 9 years of age. Chickenpox is easily
passed from one person to another. It is commonly spread from person to person through
the air by sneezing or coughing. Once a person is infected, it usually takes about
2 to 3 weeks before symptoms of the infection start.
Symptoms of chickenpox include mild headache, moderate fever and general discomfort.
These are followed by a rash of itchy, little red spots which usually start on the
chest, stomach or back, but can appear anywhere on the body. There may be only a
few spots or groups of spots, or even hundreds of spots that develop over the next
3 to 5 days. The spots will change into clear blisters filled with fluid which then
become cloudy, break open, dry, scab and heal, usually within 5 to 20 days.
Although chickenpox is generally a fairly harmless infection, it may be associated
with serious complications and/or rarely death. In children, the most common complications
are bacterial skin infections. Less frequent but very serious complications include
pneumonia, inflammation of the brain (encephalitis), Reye Syndrome (which causes brain
and liver damage), and death. Severe disease and serious complications are more likely
to occur in teenagers and adults.
ProQuad contains weakened strains of living measles, mumps, rubella and varicella
viruses. These strains of live viruses cause either mild or no symptoms of infection.
When injected the vaccine causes the body to produce its own protection by making
disease-fighting substances (antibodies) against these infections.
If a vaccinated child comes into contact with measles, mumps, rubella or varicella
virus, the body is usually ready, and produces antibodies to destroy the virus.
However, as with all vaccines, 100% protection against measles, mumps, rubella and
chickenpox cannot be guaranteed. Also it may take up to 4-6 weeks for maximum protection
to develop, so occasionally infections may occur during this time.
It is not known whether ProQuad will prevent measles, mumps, rubella or chickenpox
if it is given after you have been exposed to the natural measles, mumps, rubella
or varicella virus. Therefore, vaccination before exposure is the best way to help
protect against infection and possible serious complications.
Only one injection of ProQuad is needed to help protect against chickenpox in children
aged 12 months through 12 years.
The chance of a severe reaction from ProQuad is very small, but the risks from not
being vaccinated are very serious.
Before ProQuad is given
When your child must not be given it
Do not let your child have the vaccine if your child had an allergy to ProQuad or
any of the ingredients listed at the end of this leaflet, including gelatin.
Do not let your child have ProQuad if your child has a serious allergy to:
the antibiotic neomycin.
Symptoms of a serious allergic reaction include swelling of the face, lips, tongue,
throat, difficulty in breathing, or hives.
Do not let your child have ProQuad if:
your child has an infection with fever (high temperature)
your child has active untreated tuberculosis (TB)
your child is taking medicines which decrease the body's immune defence system (eg,
corticosteroids, cyclosporin, cancer medicines)
This does not include taking corticosteroids (eg, cortisone, prednisone) as replacement
therapy for Addison's disease.
your child has diseases which decrease the body's immune defence system, such as blood
disorders, cancers of the blood cells or lymph system (eg, leukaemia, lymphoma) and
your child has a family history of immune deficiency
your child is pregnant
Pregnancy should be avoided for 3 months following vaccination.
the expiry date on the pack has passed
If the vaccine is used after the expiry date has passed, it may not work.
If you are not sure whether your child should have ProQuad, talk to your doctor.
Do not give ProQuad to children under 12 months of age.
The safety and effectiveness of ProQuad in children below the age of 12 months have
not been established.
Before your child is given it
Tell your doctor if:
1. your child has the following medical conditions or a family history of them:
febrile convulsions (fits or seizures due to a high temperature)
low blood platelet count
2. your child has a history of serious allergy to eggs
The strains of measles and mumps viruses used to make ProQuad are grown in egg-derived
3. your child has received blood or plasma transfusions or immune globulins within the
past three months
Your doctor may decide to delay the injection of ProQuad.
4. your child is about to have a tuberculin test
This should be given either before or at the same time as the injection of ProQuad.
5. your child is breast-feeding
The vaccine should not be given if the recipient is breast-feeding or intends to breast-feed.
6. your child has any allergies to any other medicines especially to neomycin or vaccines,
or any other substances, such as foods, preservatives or dyes.
7. your child has a blood-clotting disorder or bleeds or bruises more easily. In this
case, your doctor will give your child the vaccine under the skin (subcutaneously).
If you have not told your doctor about any of the above, tell them before your child
is given ProQuad.
In rare circumstances, it is possible to catch chickenpox, including severe chickenpox,
from a person who has been vaccinated with ProQuad. This may occur in persons who
have not previously been vaccinated against chickenpox or had chickenpox, as well
as persons who fall into one of the following categories:
individuals with a weakened immune system
pregnant women who never had chickenpox
newborn babies whose mothers never had chickenpox
Whenever possible, individuals who have been vaccinated with ProQuad should attempt
to avoid close contact, for up to 6 weeks following the vaccination, with anyone who
falls into one of the categories above. Tell the doctor if there is anyone who falls
into one of the categories above and is expected to be in close contact with the person
ProQuad may be used for vaccination against measles, mumps, rubella, and chickenpox.
The appropriate time and number of injections will be determined by your doctor using
appropriate official recommendations.
Taking other medicines
Tell your doctor if your child is taking any other medicines, including any that you
buy without a prescription from your pharmacy, supermarket or health food shop.
ProQuad should not be given to children who are using the following:
medicines that decrease the immune system, such as corticosteroids (eg. prednisone),
cyclosporine, or cancer medicines
aspirin or other salicylate medicines
Your doctor will advise you whether your child is receiving any of these medicines.
Some medicines should not be used for 6 to 8 weeks after receiving ProQuad. These
aspirin or other salicylates. A serious condition called Reye Syndrome has been reported
following the use of aspirin or other salicylate medicines during a natural chickenpox
infection. Therefore, aspirin or other salicylates should be avoided for 6 weeks
following vaccination with ProQuad.
Immune globulins. Your doctor will discuss with you the possible risks and benefits
of having immune globulin injections in the 2 months following vaccination with ProQuad.
Use with other vaccines
ProQuad can be given at the same time as Haemophilus b conjugate, hepatitis B, pneumococcal
7-valent conjugate, and hepatitis A (inactivated) vaccines. The injections should
be given at different places on the body and using separate syringes. At least one
month should elapse between a dose of ProQuad and all other vaccines. If a second
dose of a varicella-containing vaccine is given, there should be a minimum of 1 month
between doses. Your doctor will decide if ProQuad should be given with other vaccines.
How ProQuad is given
How much is given
The entire contents of the vial.
How it is given
ProQuad is usually injected just under the skin or into the muscle (subcutaneously
or intramuscularly) of the upper arm or the upper thigh by a doctor or trained nurse.
If your child has a blood-clotting disorder or bleeds or bruises more easily, the
vaccine should be given under the skin because bleeding may occur following administration
into the muscle.
The vaccine should not be injected directly into veins (intravenously).
ProQuad is given by injection to persons aged 12 months through 12 years of age.
The appropriate time and number of injections will be determined by your doctor.
If your child misses a dose
If your child misses a scheduled dose, talk to your doctor and arrange another visit
as soon as possible.
After your child has been given ProQuad
Things you must do
Keep a record of your child's vaccinations and update this after each injection.
Keep your child's follow-up appointment with your doctor or clinic.
If your child is about to be injected with any immune globulin (including varicella
zoster) and your child has been injected with ProQuad within the past 2 months, tell
If your child has been given ProQuad, avoid them coming into contact, for 6 weeks,
with a person who falls into one of the following categories:
People with a weakened immune system
Pregnant women who have never had chickenpox
Newborn babies whose mothers have never had chickenpox
These people may be at risk of catching chickenpox from your child.
Things you must not do
Do not give aspirin or other salicylate medicines to your child for 6 weeks after
being given ProQuad.
A serious condition called Reye Syndrome has been reported following the use of aspirin
or other salicylate medicines during a natural chickenpox infection.
Tell your doctor or pharmacist as soon as possible if your child does not feel well
during or after having had an injection of ProQuad.
ProQuad helps protect most people from measles, mumps, rubella and varicella, but
it may have unwanted side effects in a few children. All medicines and vaccines can
have side effects. Sometimes they are serious, most of the time they are not. Your
child may need medical treatment if they get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if your child has any of the following and they are troublesome or
pain, tenderness or soreness at the injection site

Vomiting and diarrhoea
Rash including measles or varicella like rash, viral skin rash and injection site
Upper respiratory tract infection (URTI)
Swelling of the epididymis, a part of the male reproductive system
vomiting and diarrhea
These are the more common side effects of ProQuad. For the most part these have been
mild. They usually improve or disappear within a few days.
Other less common side effects have been reported with ProQuad, and some of these
were serious. These included:
allergic reactions (see below)
Seizures with fever;
Cough and bronchiolitis;
Other adverse events have been reported with at least one of the following: ProQuad,
M-M-R II, the monovalent components of M-M-R II or VARIVAX. These adverse events
