Hepatitis A vaccine

An inactivated vaccine has been developed against HEPATITIS A.

It provides a good immune response without the risk of causing disease.

The technique includes vaccine immunization withthe

Havrix 720 one injection and a reminder the following year.

For children from the age of 1 year should be used Havrix720U vaccine / 0.5 ml

One booster injection and between 6 months and 1 year. (Recall protection for 10 years).

Tolerance is good and effective protection to nearly 100% for ten years.

This vaccine can be admnistré the same time as the vaccine against HEPATITIS B but another part of the body.

Hepatitis A affects approximately 10 million people per year in the world and therefore has a certain economic cost, which jusitifie vaccination as well as some forms of hepatitis A, although rare, can be fatal.

Those at risk are:

- Travelers who travel to developing countries,

- Drain cleaners,

- Medical staff,

- Cooks.

- We considèrre it is better to vaccinate family members who are in contact with a patient.

Since late 1994, the vaccination schedule is simplified with the new vaccine. He no longer has a single injection for primary immunization and a booster six months later. The injection should be given intramuscularly in the deltoid. The vaccine protects 10 years.

Since September 1997, a new vaccine against hepatitis A and B has been developed. It allows vaccinated against hepatitis A and B at the same time.

The vaccine called Twinrix, is the first combined vaccine against hepatitis.

Knowing that at-risk populations are almost the same for hepatitis A and hepatitis B, the new vaccine is undeniable progress.

This vaccine provides equivalent to two monovalent vaccines injected into two separate sites protection.

The safety of this vaccine is excellent.

The injection should be made intramuscularly in the deltoid region

Three injections are needed

The second one month after the first and the third six months after the second.

Dual protection is set up between 2 and 4 weeks after the first injection.

At 1 month, seroconversion rates were 94% for hepatitis A and 70% for hepatitis B.

At 2 months, they are 99.5% for hepatitis A and 97.4% for hepatitis B.

After the third injection, they are practically 100%.
