WHAT HAVRIX MONODOSE IS AND WHAT IT IS USED FOR?
Havrix Monodose is a vaccine containing hepatitis A virus. It is used to boost the body’s immune system to help protect against hepatitis A infection in adults and adolescents (16 years of age and above).
HOW HAVRIX MONODOSE WORKS?
The virus is not alive so this vaccine cannot cause hepatitis A infection.
When you are given Havrix Monodose vaccine your 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 you against hepatitis A infection.
To ensure long term protection, you should receive a second (booster) vaccination 6 to 12 months after your first dose. As long as you receive the booster within 5 years, you should still be fully protected. Once you have had your booster vaccination, you 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).
