Section 10 revision date revised to January 2015

Addition of information related to the long term protectin provided by Avaxim

4.1     Therapeutic indications

AVAXIM is indicated for active immunisation against infection caused by hepatitis A virus in susceptible adults and adolescents of 16 years of age and above.

The use of AVAXIM should be based on official recommendations.

 
In section 4.2: clarification of the section and move part of the information in section 5.1

4.2     Posology and method of administration

Posology

The recommended dosage for subjects of at least 16 years of age is 0.5 millilitre for each injection.  Individuals having grown up in areas of high endemicity and/or with a history of jaundice may be immune to hepatitis A, in which case the vaccine is unnecessary. Testing for antibodies to hepatitis A prior to a decision on immunisation should be considered in such situations. If not, seropositivity against hepatitis A is not a contraindication. AVAXIM is as well tolerated in seropositive as in seronegative subjects (see Section 4.8). AVAXIM is not recommended for use in children of less than or equal to 15 years of age due to insufficient data on safety and efficacy.

Initial protection is achieved with one single dose of vaccine. Protective levels of antibody may not be reached until 14 days after administration of the vaccine. There are serological data to show that there should be continuing protection against hepatitis A for up to 36 months after a first dose in subjects who responded to the initial vaccination.

In order to provide long-term protection, a second dose (booster) of an inactivated hepatitis A vaccine should be given. The second dose is preferably given between 6 and 12 months after the primary immunisation but may be administered up to 36 months after the primary immunisation first dose (see section 5.1). It is predicted that HAV antibodies persist for many years (beyond 10 years) after the booster vaccination second dose.

Current recommendations do not support the need for further booster vaccinations for immunocompetent individuals after the initial two-dose vaccination course.

In the event that the second dose (booster) has been delayed after 36 months, there may be a decreased anti-hepatitis A antibody response. If long-term protection is required, the serum anti-hepatitis A antibody titre should be determined after AVAXIM administration of the second dose.

The vaccine may be used as a to provide the second dose (booster) in subjects from 16 years of age who received another inactivated hepatitis A vaccine (monovalent or with purified Vi polysaccharide typhoid) 6 months to up to 36 months previously.

AVAXIM is not recommended for use in children of less than or equal to 15 years of age due to insufficient data on safety and efficacy.

 
Addition of a precaution in section 4.4

4.4     Special warnings and precautions for use

Individuals having grown up in areas of high endemicity and/or with a history of jaundice may be immune to hepatitis A, in which case the vaccine is unnecessary. Testing for antibodies to hepatitis A prior to a decision on immunisation should be considered in such situations. If not, seropositivity against hepatitis A is not a contraindication. AVAXIM is as well tolerated in seropositive as in seronegative subjects (see Section 4.8).

5.       PHARMACOLOGICAL PROPERTIES

5.1     Pharmacodynamic properties

Pharmacotherapeutic group: Viral vaccine, ATC Code: J07BC02

AVAXIM confers immunity against hepatitis A virus by inducing antibody titres greater than those obtained after passive immunisation with immunoglobulin. Antibody appears shortly after the first injection and 14 days after vaccination more than 90% of immunocompetent subjects are seroprotected (titre above 20 mIU/millilitre).

One month after the first injection, almost 100% of subjects have antibody titres above 20mIU/millilitre. Serological data show continuing protection against hepatitis A for up to 36 months in subjects who responded to the first dose. In a study of 103 healthy adults who were followed serologically for three years after the first injection of AVAXIM, 99% still had at least 20 mIU/ml anti-HAV antibody at month 36.

The long-term persistence of protective antibody levels to hepatitis A virus after a second dose (booster) dose of AVAXIM is not currently available has not been fully evaluated. Nevertheless, available data (antibody titres obtained two years after the second dose) suggests that anti-HAV antibodies persist beyond 10 years after the booster vaccination second dose in healthy individuals.
