What Varilrix is ​​and what it is used for

Varilrix is ​​a vaccine used in people from 12 months of age to protect them against chickenpox (varicella). In special circumstances, Varilrix can be given to infants from the age of 9 months.

If a person is vaccinated within 3 days of being in contact with someone who has chickenpox, the vaccination may help prevent chickenpox or make the disease milder.

How Varilrix works

When a person is vaccinated with Varilrix, the immune system (the body’s natural defense system) produces antibodies that protect the person from being infected with the chicken pox virus (varicella).

Varilux contains weakened viruses and it is very unlikely that the vaccine would cause chickenpox in healthy people.

As with all vaccines, Varilrix may not provide complete protection for everyone vaccinated.

What you need to know before you/your child receives Varilrix

Do not use Varilrix:

  • if you/your child have any disease (e.g. a blood disease, cancer, infection with the human immunodeficiency virus ( HIV ) or acquired immunodeficiency syndrome ( AIDS ) or are taking any medicine (even high doses of corticosteroids ) that weakens the immune system. If you or your child receives the vaccine depends on the level of your immune system, see “Warnings and precautions” in section 2.
  • if you/your child are allergic to any ingredient in this vaccine (listed in section 6). Signs of an allergic reaction may include skin itching, shortness of breath, and swelling of the face or tongue.
  • if you/your child is allergic to neomycin (an antibiotic ). However, known contact dermatitis (skin rash on direct contact with an allergen, e.g. neomycin ) is not an obstacle to vaccination.
  • if you/your child previously had an allergic reaction to a chickenpox vaccine.
  • if you are pregnant. In addition, pregnancy must be avoided for 1 month after vaccination.

Warnings and precautions

Talk to a doctor, pharmacist, or nurse before you/your child receives Varilrix:

  • if you/your child has a serious infection with a high fever. It may be necessary to postpone the vaccination until you/your child is healthy again. A milder infection such as a cold should not require postponing the vaccination but talk to your doctor first.
  • if you/your child has a weakened immune system due to diseases (e.g. HIV infection ) and/or treatments. You/your child should be closely monitored as the response to the vaccine may not be sufficient to ensure protection against the disease (see “Do not use Varilrix” in section 2).
  • if you/your child has a bleeding disorder or bruises easily.

Fainting may occur (mainly in young people) after, or even before, any needle injection. Therefore, tell the doctor or nurse if you/your child has fainted during an injection before.

Like other vaccines, Varilrix may not give you or your child complete protection against chickenpox. However, people who have been vaccinated and get chickenpox usually get a much milder illness than people who have not been vaccinated.

In rare cases, the weakened virus it can be transferred from a vaccinated person to other people. This has mainly happened when the vaccinated person has some rashes or blisters. Healthy people who are infected in this way usually get a mild rash.

When you or your child has been vaccinated, for 6 weeks after the vaccination, avoid close contact with the following people as much as possible:

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

Other medicines and Varilrix

Tell the doctor or pharmacist if you/your child are taking, have recently taken, or maybe taking other medicines.

Tell the doctor if you or your child should be tested for tuberculosis. If such a test is performed within 6 weeks of vaccination with Varilrix, the result may be unreliable.

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

After vaccination with Varilrix, the intake of salicylic acid (a substance found in some antipyretic and pain-relieving medicines) should be avoided for 6 weeks, as it can cause a serious illness called Rey’s syndrome, which can affect any organ in the body.

Varilux can be given at the same time as other vaccines. Different injection sites are used for each vaccine.

Pregnancy and breastfeeding

Varilux should not be given to pregnant women.

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 receiving this vaccine. It is also important that you do not become pregnant within a month of receiving the vaccine. During this time, you must use effective contraception to avoid pregnancy.

Inform the doctor if you are breastfeeding or intend to start breastfeeding. The doctor decides whether you can be vaccinated with Varilrix.

Driving ability and use of machinery

Varilrix has no or negligible effect on the ability to drive and use machines. Some of the side effects mentioned in section 4 Possible side effects may, however, temporarily affect the ability to drive vehicles or use machines.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. A description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with your doctor or pharmacist if you are unsure.

Varilrix contains sorbitol and phenylalanine

This medicine contains 6 mg of sorbitol per dose.

This medicine contains 331 micrograms of phenylalanine per dose. Phenylalanine can be harmful if you have phenylketonuria (PKU), a rare, inherited disease that leads to the accumulation of high levels of phenylalanine in the body.

How Varilrix is ​​used

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

Children from the age of 12 months should receive 2 doses of Varilrix at least 6 weeks apart. The time between the first and second dose must not be shorter than 4 weeks.

In special circumstances, the first dose of Varilrix can be given to infants between 9 and 11 months of age. In that case, two doses are needed but must be given at least 3 months apart.

People who are at risk of becoming seriously ill from chicken pox, e.g. people who are being treated for cancer, may receive more doses of you. The time between the first and second dose must not be shorter than 4 weeks.

The doctor decides when vaccination should take place and with how many doses, based on official recommendations.

If you or your child has received too much Varilrix

Overdose is unlikely because the vaccine is supplied in a vial containing one dose, and is given by a doctor or nurse. Only a few cases of accidental injection have been reported, and in only a few of these were abnormal drowsiness and convulsions observed.

If you think you or your child have missed a dose of Varilrix

Contact a doctor, who will decide if a dose is needed and when it should be given.
