Description

Vaccination is the best protection against hepatitis B and its complications.

Hepatitis B is a liver infection caused by the hepatitis B virus. The vaccine is 95% effective in preventing the infection.

The vaccine is indicated for anyone who wants to reduce their risk of getting hepatitis B. Depending on the person’s age, 2 or 3 doses of the vaccine are required to ensure the best possible protection.

For people aged 1 to 19, 2 doses of the hepatitis B vaccine are enough to ensure effective protection. Everyone else will need 3 doses of the vaccine.

One dose of the hepatitis A and hepatitis B vaccine followed by one dose of the hepatitis B vaccine are offered free of charge in Grade 4 of primary school.

In healthy people, protection will last a very long time, probably for life.

Symptoms after vaccination

Some symptoms may be caused by the vaccine, e.g. redness at the injection site.

Other problems may occur by chance and are not related to the vaccine, e.g. cold, gastro, headache.

Hepatitis B vaccine is safe. In most cases, it does not cause any reaction.
