Varilrix is a vaccine for use in individuals aged 12 months and above to protect them against chickenpox. In some circumstances, Varilrix may also be administered to infants aged 9 months and above.

Vaccination within 3 days after contact with a chickenpox case may help prevent chickenpox or reduce the severity of the disease.

How Varilrix works

When a person is vaccinated with Varilrix, the immune system (the body's natural defense system) will produce antibodies to protect the person from infection by the chickenpox virus. Varilrix contains weakened viruses, making it highly unlikely to cause chickenpox in healthy individuals.

Like any vaccine, Varilrix may not protect all vaccinated individuals completely.

Do not useVarilrix

• If you or your child has any disease (such as blood disorders, cancer, Human Immunodeficiency Virus (HIV) infection or Acquired Immunodeficiency Syndrome (AIDS)) or is taking any medication (including high doses of corticosteroids) that may weaken the immune system..Whether you or your child receives the vaccine will depend on the level of your defenses..See section 2 “Contraindications and precautions”.
• If you or your child is allergic to any of the components of this vaccine (including those listed in section 6). The signs of an allergic reaction may include: skin rash with itching, difficulty breathing and swelling of the face or tongue.
• If you or your child is allergic to neomycin (an antibiotic). A history of contact dermatitis (skin rash produced when the skin comes into direct contact with allergens such as neomycin) should not be a reason not to vaccinate. However, consult your doctor first.
• If you or your child has had a previous allergic reaction to any varicella vaccine.
• If you or your daughter is pregnant. Additionally, pregnancy should be avoided for 1 month after vaccination.

Contraindications and precautions

Consult your doctor, pharmacist or nurse before you or your child receives Varilrix:

• If you or your child has a severe infection with high fever. It may be necessary to postpone the vaccination until recovery. A minor infection, such as a cold, does not require postponing the vaccination. However, consult your doctor first.
• If you or your child has a weakened immune system due to diseases (e.g., HIV infection) and/or treatments. You or your child should be closely monitored since the response to the vaccine may not be sufficient to ensure protection against the disease (see section 2 “Do not use Varilrix”).
• If you have bleeding problems or bruise easily.

Before or after any injection, dizziness may occur (especially in adolescents), so inform your doctor or nurse if you or your child has fainted on previous occasions after receiving an injection..

Like other vaccines, Varilrix may not completely protect you or your child against chickenpox. However, people who have been vaccinated and develop chickenpox usually have a very mild disease compared to those who have not been vaccinated.

In rare cases, the weakened virus may be transmitted from a vaccinated person to others. Normally, this occurs when the vaccinated person has some skin lesions or blisters. Healthy people who become infected in this way usually only develop a mild skin rash that is not harmful.

After vaccination, you or your child should avoid, as much as possible, close contact with the following people for 6 weeks after vaccination:

• people with weakened immune systems,
• pregnant women who have not had chickenpox or have not been vaccinated against chickenpox,
• newborn babies of mothers who have not had chickenpox or have not been vaccinated against chickenpox.

Other medicines and Varilrix

Inform your doctor or pharmacist if you or your child is taking, has taken recently or may need to take any other vaccine and/or medicine.

Inform your doctor if you or your child needs to undergo a skin test to detect possible tuberculosis.If this test is performed within 6 weeks after administration of Varilrix, the result may not be reliable.

The vaccination should be postponed for at least 3 months if you or your child has received a blood transfusion or human antibodies (immunoglobulins).

Aspirin or other salicylates (a substance present in some medications used to reduce fever and relieve pain) should be avoided for 6 weeks after vaccination with Varilrix, as this may cause a serious disease called Reye's syndrome that can affect all organs of the body.

Varilrix can be administered at the same time as other vaccines. A different injection site will be used for each vaccine.

Pregnancy and breastfeeding

Varilrix should not be administered to pregnant women.

If you or your daughter is pregnant or breastfeeding, or if you think you may be pregnant or intend to become pregnant, consult your doctor or pharmacist before receiving the vaccine. It is also important that you or your daughter do not become pregnant for 1 month after vaccination. During this time, an effective contraceptive method should be used to avoid pregnancy.

Inform your doctor if you or your daughter is breastfeeding or intends to do so. Your doctor will decide whether you or your daughter should receive Varilrix..

Driving and operating machinery

Varilrix has no or negligible influence on the ability to drive and operate machinery. However, some of the effects mentioned in section 4 "Possible adverse effects" may temporarily affect the ability to drive or operate machinery.

Varilrix contains sorbitol and phenylalanine

This vaccine contains 6 mg of sorbitol in each dose.

This vaccine contains 331 micrograms of phenylalanine in each dose. Phenylalanine may be harmful in cases of phenylketonuria (PKU), a rare genetic disorder in which phenylalanine accumulates because the body is unable to eliminate it correctly.

Varilrix is injected under the skin or into a muscle, either in the upper arm or the outer thigh.

People aged 12 months and older should receive 2 doses of Varilrix with at least 6 weeks between them. The time between the first and second dosesmust notbe less than 4 weeks.

In some cases, the first dose of Varilrix can be administered to babies aged 9 to 11 months. In these cases, 2 doses are needed and should be administered with at least 3 months between them.

People at risk of severe chickenpox, such as those receiving cancer treatment, may receive additional doses. The interval between dosesmust notbe less than 4 weeks.

Your doctor will determine the appropriate time and number of doses based on the relevant official recommendations.

If you or your child receive more Varilrix than you should

Overdose is very unlikely because the vaccine is provided in a single-dose vial and is administered by a doctor or nurse. However, if you or your child receive more Varilrix than you should, consult your doctor, pharmacist, or nurse immediately or call the Toxicology Information Service, phone 91 562 04 20.

A few cases of accidental administration have been reported, and in some of them, abnormal somnolence and seizures (convulsions) were noted.

If you think you or your child forgot to receive a dose of Varilrix

Contact your doctor, who will decide if a dose is needed and when to administer it.

-------------------------------------------------------------------------------------------------------------

This information is intended solely for healthcare professionals:

As with all injectable vaccines, adequate medical supervision and availability of medical treatment should be ensured in case of an infrequent anaphylactic reaction following administration of the vaccine.

Allow the alcohol and other antisepsis agents to evaporate from the skin before injecting the vaccine, as they may inactivate the attenuated viruses in the vaccine.

Varilrix should not be administered by intravascular or intradermal route.

In the absence of compatibility studies, this medicinal product should not be mixed with other medicinal products.

Visually inspect the solvent and the reconstituted vaccine for any foreign particles and/or abnormal physical appearance before administration. If any are observed, do not administer the vaccine.

The vaccine should be reconstituted by adding the entire contents of the pre-loaded syringe of solvent to the vial containing the powder.

To know how to insert the needle into the syringe, read the instructions provided with images 1 and 2 carefully. However, the syringe provided with Varilrix may be slightly different (without a screw thread) from the syringe in the image. In this case, the needle should be inserted without screwing.

Always hold the syringe by the body, not by the plunger or the Luer lock adapter (ABL), and keep the needle in the syringe axis (as shown in image 2). Otherwise, the ABL may be deformed and cause leaks.

If the ABL is detached during the syringe assembly, use a new dose of the vaccine (new syringe and vial).

1. Remove the syringe cap by turning it counterclockwise (as shown in image 1).

Please follow the next steps, regardless of whether the ABL turns or not:

1. Insert the needle into the syringe by gently engaging the needle cone with the ABL and turning it a quarter of a turn clockwise until it locks (as shown in image 2).

1. Remove the needle cap (it may be difficult).

1. Add the solvent to the powder. The mixture should be shaken well until the powder is completely dissolved.

Due to small pH variations, the color of the reconstituted vaccine may vary from light orange to pink. This is normal and does not affect the vaccine's performance. Do not administer the vaccine if you observe any other variation.

1. Remove the entire contents of the vial

1. A new needle should be used to administer the vaccine. Remove the needle from the syringe and insert the injection needle, repeating step 2 above.

After reconstitution, it is recommended to administer the vaccine as soon as possible. However, it has been demonstrated that the reconstituted vaccine can be stored for up to 90 minutes at room temperature (25°C) and up to 8 hours in the refrigerator (between 2°C and 8°C). If it is not used within the recommended storage and use conditions, the reconstituted vaccine should be discarded.

The disposal of unused vaccine and all materials that have come into contact with it should be carried out in accordance with local regulations.
