What it is and what it is used for

for

Havrix Junior Monodose is a vaccine containing the hepatitis A virus. It is used to boost the body's immune system to help protect against hepatitis A infection in children and adolescents from 1 year up to and including 15 years of age. How Havrix Junior Monodose works

  • The virus is not alive so this vaccine cannot cause hepatitis A infection.
  • When your child is given Havrix Junior Monodose their body will make antibodies (the body's natural defence system) against the hepatitis A virus.
  • After 2 to 4 weeks, these antibodies will have been produced and will protect your child against hepatitis A infection.
  • To ensure long term protection, your child should receive a second (booster) vaccination 6 to 12 months after their first dose. As long as the booster is given within 3 years, they should still be fully protected. Once the booster vaccination is given, they are not expected to need an additional dose of Havrix.
  • Having this vaccine will only protect against hepatitis A and not against any other type of hepatitis virus or any other illness that can cause hepatitis (inflammation of the liver). Some general information on hepatitis A infection is given at the end of this leaflet.

2 What you need to know before your child receives Havrix Junior Monodose Havrix Junior Monodose should not be given if:

  • your child is allergic (hypersensitive) to any of the ingredients of Havrix (listed in section 6)
  • your child is allergic to any other hepatitis A vaccine or neomycin, an antibiotic that may be present in very small amounts

-1-

• •

your child is aged 16 years or over, as another product, Havrix Monodose is recommended for this age group your child has a high temperature (fever). The presence of a minor infection such as a cold should not be a problem. Talk to your doctor first.

Do not give your child Havrix if any of the above apply to them. If you are not sure, talk to their doctor, nurse or pharmacist before they have Havrix. Warnings and precautions Check with the doctor, nurse or pharmacist before Havrix Junior Monodose is given if:

  • your child is on dialysis for a kidney problem
  • your child already has the hepatitis A virus or is living with someone who has caught the hepatitis A virus recently
  • your child has any problem with the way their body fights disease (immunosuppression). If any of the above apply to your child, Havrix Junior Monodose can still be given, but your child may not develop enough antibodies after a single injection to protect them against infection. In these cases, the doctor or nurse may decide that extra doses of Havrix Junior Monodose should be given and may take a blood test to measure the antibody levels in the blood before or after the vaccine is given. Sometimes, an antibody injection will be given to try and protect your child until the vaccine starts to work. This can be given at the same time as they have the vaccine but will be injected into the opposite arm. Fainting can occur (mostly in adolescents) following, or even before, any needle injection. Therefore tell the doctor or nurse if your child fainted with a previous injection. Check with the doctor, nurse or pharmacist before Havrix Junior Monodose is given if your child has a bleeding problem or bruises easily. Other medicines or vaccines and Havrix Junior Monodose Tell your doctor or nurse if your child is taking, about to be given or has recently taken, any other medicine. Havrix Junior Monodose can be given at the same time as most other routine childhood vaccines. These vaccines will be given at different injection sites. In particular talk to your doctor if:
  • your child is taking a medicine that can affect the way in which their body fights disease. Your child should not have Havrix if they are taking this type of medicine Pregnancy and breast-feeding
  • Women who are pregnant may sometimes be vaccinated. If they are over 16, they should not receive the Havrix Junior Monodose, but should have the Havrix Monodose vaccine instead.
  • Talk to their doctor or nurse if the person to be vaccinated thinks they are, or that they might be, pregnant.
  • Talk to their doctor or nurse if the person to be vaccinated is breast-feeding. It is sometimes possible to have the vaccine if they are breast-feeding. Havrix Junior Monodose contains neomycin, potassium, sodium and phenylalanine Please tell your doctor if your child has had an allergic reaction to neomycin (antibiotic). This medicine contains potassium, less than 1 mmol (39 mg) per 1 mL dose, i.e. essentially 'potassium-free'.

-2-

This medicine contains less than 1 mmol sodium (23 mg) per 1 mL dose, that is to say essentially 'sodium-free'. This vaccine contains 83 micrograms of phenylalanine in each dose. Phenylalanine may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine builds up because the body cannot remove it properly.

How to take it

Havrix Junior Monodose is for use in children and adolescents from 1 year up to and including 15 years of age. Adolescents 16 years and above should receive Havrix Monodose. A single dose of 0.5 mL is injected into the muscle in the upper arm or thigh. The vaccine should never be given into the buttock. The vaccine should never be given into a vein. The first dose of vaccine should protect your child from infection with hepatitis A virus within 2 to 4 weeks. Protection should last for at least 1 year. The best way to ensure that protection continues for at least 10 years is to receive a second (booster) dose of the vaccine. This should be given 6 to 12 months after the first injection. If the date for the booster injection is missed but a second dose is given within 3 years of the first dose, protection against hepatitis A infection should still continue for at least 10 years. If a second dose is not given within 3 years of the first dose, the doctor may decide that vaccination should start again, with 2 doses of vaccine within 1 year.

Disposal Any unused product or waste material should be disposed of in accordance with local requirements. General information on hepatitis A Hepatitis A virus causes an infection of the liver. You can catch the virus by eating or drinking contaminated food or water. The virus is present in the bowel movement (motion) of infected people, even when they may have no signs of the infection. You can catch hepatitis A infection in any country but the risk is highest in places and countries where sanitation and food and water hygiene are poor. After catching the virus, it can be up to 6 weeks before signs of illness are seen. Some people have the virus and never get ill but they can still infect other people during this time. The main signs of the illness include sickness, yellowing of the skin and eyes (jaundice), fever and headache. These signs are all due to an inflammation of the liver while it is infected with the virus. Most patients get better, usually after a couple of weeks or months, but a few people may take up to a year to make a full recovery. While recovering, people affected with hepatitis A may be unable to work. They may not be able to drink alcohol and may need to avoid certain foods according to their doctors' advice. Severe complications are very rare but sometimes the liver stops working and hospital care is needed until the infection gets better. There are many other types of virus that can cause hepatitis. The signs may be the same as in hepatitis A infection but the viruses are not always caught through food and drink.

4.1. Therapeutic indications

Active immunisation against HAV infection from 1 year up to and including 15 years of age.

The vaccine is particularly indicated for those at increased risk of infection or transmission. It is also indicated for use during outbreaks of hepatitis A infection.

4.2. Posology and method of administration

Posology

Children/adolescents (1-15 years)

Primary immunisation consists of a single dose given intramuscularly. This provides anti-HAV antibodies for at least one year.

This vaccine confers protection against hepatitis A within two to four weeks.

In order to obtain more persistent immunity, for at least 10 years, a booster dose is recommended between 6 and 12 months after primary immunisation.

Booster vaccination delayed up to 3 years after the primary dose induces similar antibody levels as a booster dose administered within the recommended time interval.

Current recommendations do not support the need for further booster vaccination among immunocompetent subjects after a 2-dose vaccination course (see section 5.1).

Havrix Junior Monodose can be used as a booster in subjects previously immunised with any inactivated hepatitis A vaccine.

In the event of a subject being exposed to a high risk of contracting hepatitis A within two weeks of the primary immunisation dose, human normal immunoglobulin may be given simultaneously with this vaccine at different injection sites.

Method of administration

The vaccine should be injected intramuscularly in the deltoid region or into the antero-lateral part of the thigh in young children. The vaccine should not be administered in the gluteal region.

The vaccine should never be administered intravascularly.

The vaccine should not be administered subcutaneously/intradermally since administration by these routes may result in a less than optimal anti-HAV antibody response. In subjects with a bleeding disorder who are at risk of haemorrhage following intramuscular injection (e.g. haemophiliacs), this vaccine may be administered by deep subcutaneous injection as per local guidance. Firm pressure should be applied to the injection site (without rubbing) for at least two minutes.

4.3. Contraindications

Hypersensitivity to the active substance, to any of the excipients listed in section 6.1, or to neomycin (present at traces).

4.4. Special warnings and precautions for use

Immunisation should be postponed in subjects suffering from an acute severe febrile illness. The presence of a minor infection, such as a cold, should not result in the deferral of vaccination.

As for all vaccines, appropriate medication e.g.epinephrine (adrenaline) should be readily available for immediate use in case of anaphylaxis.

It is possible that subjects may be in the incubation period of a hepatitis A infection at the time of immunisation. It is not known whether Havrix Junior Monodose will prevent hepatitis A in such cases.

In haemodialysis patients and in subjects with an impaired immune system, adequate anti-HAV antibody titres may not be obtained after the primary immunisation and such patients may therefore require administration of additional doses of vaccine.

Syncope (fainting) can occur following, or even before, any vaccination especially in adolescents as a psychogenic response to the needle injection. This can be accompanied by several neurological signs such as transient visual disturbance, paraesthesia and tonic-clonic limb movements during recovery. It is important that procedures are in place to avoid injury from faints.

Excipients

This vaccine contains 83 micrograms of phenylalanine in each dose. Phenylalanine may be harmful to patients that have phenylketonuria (PKU).

This medicine contains potassium, less than 1 mmol (39 mg) per 0.5 mL dose, i.e. essentially 'potassium- free'.

This medicinal product contains less than 1 mmol sodium (23 mg) per 0.5 mL dose, that is to say essentially 'sodium- free'.

4.5. Interaction with other medicinal products and other forms of interaction

Simultaneous administration of Havrix with normal immunoglobulin does not influence the seroconversion rate to Havrix, however, it may result in a lower antibody titre. A similar effect could be observed with Havrix Junior Monodose.

Preliminary data on the concomitant administration of Havrix, at a dose of 720 ELISA units/mL, with recombinant hepatitis B virus vaccine suggests that there is no interference in the immune response to either antigen. Havrix Junior Monodose can be given concomitantly with monovalent and combination vaccines comprised of measles, mumps, rubella and varicella. When concomitant administration is considered necessary the vaccines must be given at different injection sites.

Havrix Junior Monodose must not be mixed with other vaccines in the same syringe.

4.6. Fertility, pregnancy and lactation

Pregnancy

There are no or limited amount of data from the use of this vaccine in pregnant women. Animal studies are insufficient with respect to reproductive toxicity. The use of this vaccine may be considered during pregnancy, if necessary.

Breast-feeding

It is unknown whether this vaccine is excreted in human milk. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from therapy taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman.

Fertility

No fertility data are available.

4.7. Effects on ability to drive and use machines

No studies of the effects of Havrix Junior Monodose on the ability to drive and use machines have been performed. However, some of the effects mentioned under section 4.8 “Undesirable effects” may temporarily affect the ability to drive or use machines.

4.8. Undesirable effects

The safety profile presented below is based on data from more than 5300 subjects that participated in clinical trials, plus reactions observed through post-marketing surveillance. It should be noted that it was not possible to calculate the frequency of reactions from the post-marketing data, therefore the frequency is noted as “Not known”.

The most frequently reported reactions are pain and redness at site of injection (Havrix Monodose has reports in over 50% of doses, Havrix Junior Monodose has reports in 18.2% of doses overall). Swelling at the site of injection was the next most frequently reported reactions.

Frequencies per dose are defined as follows:

Very common:

≥ 1/10

Common:

≥ 1/100 to < 1/10

Uncommon:

≥ 1/1,000 to < 1/100

Rare:

≥ 1/10,000 to < 1/1,000

Very rare:

< 1/10,000

Not Known:

Cannot be estimated from the data available

Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness

* refers to adverse reaction reported only for Havrix Monodose (1mL adult dose)

** refers to adverse reactions reported only for Havrix Junior Monodose (0.5mL children's dose)

# this adverse reaction was identified through post-marketing surveillance but was not observed in randomised controlled clinical trials. The frequency category of rare was estimated from a statistical calculation based on the total number of paediatric patients exposed to Havrix in randomised controlled clinical trials (n=4574).
