1. What VARIVAX is and what it is used for

VARIVAX is a vaccine useful for protecting adults and children against chickenpox. Vaccines are used
to protect you or your child from infectious diseases.
VARIVAX can be administered to subjects aged 12 months or older.
VARIVAX can be administered to children aged 9 months or older in specific
circumstances, such as to align with national vaccination programs or in cases of
epidemics.
VARIVAX can also be administered to subjects who have never contracted the chickenpox
virus, but who have been in contact with people affected by chickenpox.
Vaccination within 3 days of exposure can help prevent chickenpox or reduce its
severity by causing a smaller number of skin lesions and a shorter duration of the illness. Furthermore,
limited data indicate that vaccination up to 5 days after exposure can reduce the severity of
the illness.
Like other vaccines, VARIVAX does not completely protect all subjects from chickenpox
naturally acquired.

2. What you need to know before your child or you receive VARIVAX

Do not use VARIVAX if:

• you or your child is allergic to any chickenpox vaccine or any of the other ingredients of this vaccine (listed in section 6) or to neomycin (which may be present as a residual trace).
• you or your child has blood disorders or any type of malignant neoplasm including leukemias and lymphomas affecting the immune system.
• you or your child is being treated with medicines that suppress the immune system (including high doses of corticosteroids).
• you or your child has any disease (such as Human Immunodeficiency Virus (HIV) or Acquired Immunodeficiency Syndrome (AIDS)) or is taking medicines that can weaken the immune system. The decision to administer the vaccine to you or your child will depend on the level of your immune defenses.
• you or your child has a family member born with immunodeficiency or a family history of immunodeficiency.
• you or your child has active, untreated tuberculosis.
• you or your child has a fever with a temperature higher than 38.5 °C; however, a low-grade fever is not in itself a reason not to be vaccinated.
• you are pregnant. Furthermore, pregnancy should be avoided in the first month following vaccination.

Warnings and precautions
In rare circumstances, it is possible to contract chickenpox, including severe chickenpox, from a person who has
been vaccinated with VARIVAX. This can occur in people who have not been previously
vaccinated or have not had chickenpox, as well as in people who fall into one of the following
categories:
individuals with a weakened immune system.
pregnant women who have never had chickenpox.
infants whose mothers have never had chickenpox.
Individuals who have been vaccinated with VARIVAX, where possible, should try to avoid
close contact, for at least 6 weeks after vaccination, with anyone who falls into one of the
categories described above. Tell your doctor if there is someone who falls into one of the categories above
and who may have close contact with the vaccinated person.
Consult your doctor or pharmacist before you or your child receive VARIVAX:

• if you or your child has a weakened immune system (such as due to an HIV infection). You or your child should be closely monitored because the response to the vaccine may not be sufficient to guarantee protection against the disease (see section 2 “Do not use VARIVAX if”).

Other medicines (or other vaccines) and VARIVAX
Tell your doctor or pharmacist if you or your child is taking or has recently taken
any other medicines (or other vaccines).
If other vaccines need to be administered at the same time as VARIVAX, your doctor or
healthcare professional will tell you if this is possible. VARIVAX can be administered
in the same vaccination session with other childhood vaccines such as: the measles, mumps and
rubella (MMR) vaccine, the vaccines against Haemophilus influenzaetype b, hepatitis B, diphtheria, tetanus, pertussis
(whooping cough) and the oral polio vaccine.
VARIVAX can be administered with a pneumococcal conjugate vaccine during the same
vaccination session, at separate injection sites.
Vaccination should be postponed for at least 5 months after plasma or blood transfusions, or
administration of normal human immunoglobulins (sterile solution of antibodies produced
naturally from donated human blood) or varicella zoster immunoglobulin (VZIG).
After vaccination with VARIVAX, in the first month following vaccination, you or your
child should not receive any immunoglobulins, including VZIG, unless your doctor decides
that this is necessary.
Those receiving the vaccine should avoid the use of products containing aspirin (salicylates) for
the 6 weeks following vaccination with VARIVAX as these medicines can cause
a serious condition called Reye's syndrome that can affect all organs of the body.

Pregnancy and breastfeeding
VARIVAX should not be administered to pregnant women.
If you are pregnant, suspect you may be pregnant, are planning a pregnancy, or are breastfeeding,
ask your doctor or pharmacist for advice before receiving this vaccine. It is also
important to avoid pregnancy in the first month following vaccination. During this
period of time, you should use an effective method of contraception to avoid pregnancy.
Tell your doctor if you are breastfeeding or intend to breastfeed. The doctor will decide whether to administer or
not administer VARIVAX.

Driving and operating machinery
There is no information to suggest that VARIVAX has effects on the ability to drive
vehicles or operate machinery.

VARIVAX contains sodium
This medicine contains less than 1 mmol (23 mg) of sodium per dose, that is to say essentially “sodium-free”.

VARIVAX contains potassium
This medicine contains less than 1 mmol (39 mg) of potassium per dose, that is to say essentially “potassium-free”.

3. How VARIVAX is administered

VARIVAX will be administered by a doctor or healthcare professional.
VARIVAX must be administered by injection as indicated below:
Children from 9 months to 12 months of age:
In particular circumstances (alignment with national vaccination programs or in cases of
chickenpox epidemic), VARIVAX may be administered between 9 and 12 months of age. To
ensure optimal protection against chickenpox, two doses must be administered
at least three months apart.
Children from 12 months to 12 years of age:
To ensure optimal protection against chickenpox, two doses of VARIVAX must be administered
at least one month apart.
Children from 12 months to 12 years of age with asymptomatic HIV:
VARIVAX must be administered in 2 doses by injection 12 weeks apart. Contact your
healthcare professional for further information.
Subjects 13 years of age or older:
VARIVAX is administered in 2 doses by injection 4 - 8 weeks apart.
The number and frequency of doses to be administered must be decided by the doctor based on
official recommendations.
VARIVAX should not be administered to children under 9 months of age.
VARIVAX must be administered intramuscularly or subcutaneously in the outer area of the
thigh or arm. For intramuscular administrations, the thigh area is generally preferred in young
children, while the arm is the preferred injection site in older subjects.
In case of blood coagulation disorders or low platelet levels in the blood, the injection
will be administered subcutaneously.
The doctor or healthcare professional will ensure that VARIVAX is not injected directly into a
blood vessel.

If you use more VARIVAX than you should
It is very unlikely that an overdose will occur as the vaccine is supplied in single-dose vials
and is administered by a doctor or healthcare professional.

If you think you have forgotten to take a dose of VARIVAX
Contact your doctor who will decide if a dose is necessary and when to administer it.
