Hepatitis A.

In Hungary 3 immunizations have been registered that contain deactivated virus cells against Hepatitis A.

For whom should it be considered?

• Everyone who visits a territory with possible risk of contagion /Central and South America, Mexico, Asia (except for Japan), Africa, Eastern Europe, and certain South European countries/ .
• Those who are especially endangered due to their specific illness or way of living (bleeders, people using intravenous drugs, homosexual oriented people, people suffering from chronic liver disease).
• People who can be endangered by infection during work (laboratory workers, medical workers, water workers).
• Everyone in a community in case of a Hepatitis A epidemic.

When is it to be given?

For small children, the first dose can be given between 12-23 months.

For travellers it is recommended to receive the first dose at least 4 weeks before travel, but minimum 2 weeks are needed for the vaccination to take effect.

Revaccination is needed for reaching long term protection. It can be carried out between 6 months and 5 years after receiving the first dose, but is suggested between 6 - 12 months following the first one.

The vaccination can also be used simultaneously with other immunizations.

How long is the protection period?

One dose of Hepatitis A vaccination gives protection for 3-5 years. When receiving the complete Hepatitis A vaccination series (which consists of 2 doses) a protection period of at least 20 years can be obtained.

When is it contraindicated?

• In case of severe allergic symptoms after receiving the first dose of Hepatitis A.
• In case it’s known that someone is allergic to any other vaccinations or any component of Hepatitis A vaccination.
• In case of any other ongoing severe acute illnesses.

Based on current knowledge, it is not harmful either for pregnant women or for the new-borns, but is only recommended, if the pregnant woman is at possible risk of contagion.
