1. What is HBVAXPRO 5 micrograms and what is it used for

This vaccine is indicated for active immunization against hepatitis B virus infection caused by all known subtypes, in individuals from birth to 15 years of age considered at risk of exposure to hepatitis B virus.

It can be expected that immunization with HBVAXPRO will also prevent hepatitis D, since hepatitis D does not occur in the absence of hepatitis B infection.

The vaccine does not prevent infections caused by other agents such as hepatitis A, hepatitis C, and hepatitis E, or by other pathogens known to infect the liver.

3. How HBVAXPRO 5 micrograms is administered

Dose

The recommended dose per injection (0.5 ml) is 5 micrograms in individuals from birth to 15 years of age.

A vaccination cycle should include at least three injections.

Two vaccination schedules can be recommended:

  • two injections with a one-month interval followed by a third injection 6 months after the first administration (0, 1, 6 months).
  • if rapid immunity is required: three injections with a one-month interval and a fourth dose 1 year later (0, 1, 2, 12 months).

In case of recent exposure to hepatitis B virus, a first dose of HBVAXPRO can be administered along with the appropriate dose of immunoglobulin.

Some local vaccination schedules currently recommend a booster dose. Your doctor, pharmacist or nurse will inform you if you need a booster dose.

Method of administration

The doctor or nurse will administer the vaccine by injection into the muscle. The preferred injection site in newborns and infants is the upper part of the thigh. The preferred injection site in older children and adolescents is the muscle of the upper arm.

This vaccine should never be administered into a blood vessel.

Exceptionally, the vaccine can be administered subcutaneously in patients with thrombocytopenia (decreased blood platelets) or in individuals at risk of bleeding.
