Pharmacological action of

The Havrix vaccine provides protection against hepatitis A by forming specific immunity by inducing the production of antibodies against hepatitis A virus (HAV), as well as the activation of cellular immunity mechanisms.

Clinical studies have shown that seroprotection (> 20 mIU / ml) is achieved in 99% of those vaccinated 30 days after the first dose. The data obtained when the vaccine was administered twice with an interval of 6-12 months, we can conclude that 97% of the vaccinated 25 years after the course will have a protective antibody titer (> 20 mIU / ml).

When studying the kinetics of the immune response, it was found that after administration of a single dose of the Havrix vaccine, seroprotection is achieved on day 13 in 79% of vaccinees, on day 15 in 86.3%, and on 17- day in 95.2% day 1, and 99% – on day 19, i.e. these time intervals are shorter than the average incubation period for hepatitis A (4 weeks).

The efficacy of the Havrix vaccine was evaluated during outbreaks of disease affecting large populations (Alaska, Slovakia, USA, Great Britain, Israel, Italy), as well as in family centers and organized children’s groups. These studies showed that Havrix vaccination led to the cessation of outbreaks. With vaccine coverage of at least 80% of the susceptible population, relief of the outbreak is achieved within 4-8 weeks.

To ensure long-term protection, a second (booster) dose should be administered between 6 and 12 months. after the first dose. It was found that revaccination carried out in the period up to 12-60 months after vaccination induces the production of the same level of antibodies as revaccination carried out after 6-12 months. after vaccination.

Based on the available data, it can be concluded that persons with unchanged immune status after a two-dose vaccination course, there is no need to carry out additional revaccination.

Indications

Contraindications

Persons with chronic liver disease or an increased risk of liver disease (chronic carriers of hepatitis B, C viruses, delta, people suffering from chronic hepatitis of alcoholic, autoimmune, toxic, drug and other genesis, persons with Wilson-Konovalov’s disease, hepatoses and hepatopathies).

In regions of moderate or high endemicity, hepatitis A vaccination is recommended for all susceptible populations.
