Vaccine is indicated for active immunization against hepatitis B virus infection (HBV) caused by all known 
subtypes. 

Posology 
1 dose, 20 micrograms (1ml suspension) is intended for use in youth (from 16 years of age) and adults. 
The primary immunization regimen consists of three doses: 
- 1
st dose: at elected date 
- 2
nd dose: 1 month after the first dose 
- 3
rd dose: 6 month after the first dose 
Booster vaccination: 
Under results of studies the WHO does not recommend booster vaccination among immunocompetent 
subjects who have responded to 3 doses, as it has been shown that 3 dose series of hepatitis B immunization 
protects for as long as 15 years, and that a protective anamnestic response occurs after exposure to HBV, 
even if protective antibodies have been lost over time.

Official vaccination programs of booster vaccination should be respected.
In special cases, when rapid optimal immune response is required i.e., neonates born from Hepatitis B 
infected mothers, someone who has been exposed to the virus (e.g. needle stick with contaminated needle) or 
certain travelers to high-risk areas an alternative schedule can be used:
2 
- 1st dose: at elected date 
- 2nd dose: 1 month after the first dose 
- 3rd dose: 2 month after the first dose 
4
th dose: 12 months after the first dose to assure long term protection. 
Additional dose(s) of vaccine may be required in hemodialysis or immunodeficient patients, since protective 
antibody titers (≥10 IU/L) may not be obtained after the primary immunization series. 
Determination of antibodies titers is recommended. 
In cases where someone has or might have been recently exposed to the HBV (contamination by injured skin 
or mucosa, neonates born from Hepatitis B infected mothers) to be recommended the first dose of Euvax B 
vaccine administers simultaneously with HBIg. Injection must be given at a separate site.

The administration of Euvax B vaccine should be postponed in patients suffering from an acute, severe 
febrile illness. 
In patients suffering from multiple sclerosis, any stimulation of the immune system can induce exacerbation 
of their symptoms. Therefore, for these patients the benefits of vaccination against Hepatitis B should be 
weighed against the risks of exacerbation of multiple sclerosis. 
It is considered that vaccination in patients in latent or progressive states of Hepatitis B may not affect the 
course of these diseases. 
Because of the long incubation period of hepatitis B it is possible for unrecognized infection to be present at 
the time of immunization. The vaccine may not prevent hepatitis B infection in such cases. 
The vaccine will not prevent infection caused by other pathogens known to infect the liver such as hepatitis 
A (HAV), hepatitis C (HCV) and hepatitis E (HEV) viruses. 
As with all injectable vaccines, appropriate medical treatment should be always readily available in 
case of rare anaphylactic reactions following the administration of the vaccine. 
The potential risk of apnoea and the need for respiratory monitoring for 48-72h should be considered when 
administering the primary immunization series to very premature infants born < 28 weeks of gestation) and 
particularly for those with a previous history of respiratory immaturity. As the benefit of vaccination is high 
in this group of infants, vaccination should not be withheld or delayed. 
Euvax B vaccine should not be administered in the buttock or intradermal since this may not guarantee 
optimal immune response. 
Vaccine should not be administered intravenously. 

Hepatitis B vaccine can be given concomitantly with BCG, diphtheria, tetanus, pertussis, mumps, measles, 
rubella, and polio vaccines. 
Different vaccines should always be administered at different injection using different needles and syringes. 
Euvax B vaccine can be concomitantly administered with HBIg using at different injection site. 

Pregnancy 
The effect of the HBsAg on fetal development has not been assessed. However, as with all inactivated viral 
vaccines, the risks to the fetus are considered to be negligible. 
Euvax B vaccine should be used during pregnancy only when clearly needed and the possible advantages 
outweigh the possible risks for the fetus. 
Lactation 
The effect on breast-fed infants of the administration of Euvax B vaccine to their mothers has not been 
evaluated in clinical studies. No contraindication has been established.

No available data.

Because reactions from post-market surveillance are reported voluntarily from a population of uncertain size, 
it is not possible to reliably estimate their frequency.

No available data in medical literature shown adverse effect of vaccine in cases of overdose. 

Pharmacotherapeutic group: Hepatitis B vaccine, ATC code: J07BC01.
Euvax B vaccine contains purified hepatitis B surface antigen produced in yeast cells (Saccharomyces 
cerevisiae) by recombinant DNA technology (gene coding for main surface antigen HBV implantation).
Euvax B vaccine induces high titers of humoral antibodies against HbsAg 
5 clinical trials were conducted in Korea to compare the immunogenicity and safety of Euvax B vaccine with 
plasma-derived vaccine (carriers plasma-derived hepatitis B antigen). Vaccines were administrated at 
intervals of 0, 1, and 2 months and 0, 1, and 6 months. The immunogenicity of the recombinant HBV 
vaccine was as good as the plasma-derived HBV vaccine, when considering the seroconversion rates and the 
Geometric Mean Titers.
Overall, available data indicate that both schedule 0, 1, 2 months and 0, 1, 6 months are effective, but 
schedule 0, 1, 6 to be better for long-term immunogenicity. 
There was no case observed of HBsAg seropositivity or episode of clinical hepatitis B among study subjects 
during these studies. Adverse reactions observed in study groups after vaccination were mild 
and symptoms were temporary. 
The safety and immunogenicity of Euvax B vaccine was documented in all age groups. 
In randomized, controlled clinical studies the immunogenicity of Euvax B vaccine and other recombinant 
DNA yeast-derived vaccine was compared. Results shown that immunization after Euvax B vaccine is not 
less than after compared vaccine. 
Infants vaccinated with Euvax B vaccine 10 mcg at intervals 0,1,6 months (first dose – 1st day of life) in 
infants, 100% (93/93) of subjects developed anti-HBs antibody titers > 10 mIU/ml correlates with protection 
to HBV infection. 
Geometric Mean Titers (GMT) were 2334.9 mIU/ml. Antibody titres were determined at month 8. 
In clinical study with subjects aged 10 to 15 years vaccinated with Euvax B vaccine 10 mcg at intervals 0, 1, 
6 months, 100% (91/91) of subjects developed anti-HBs antibody titers correlates with protection to HBV 
infection. Geometric Mean Titres (GMT) were 3396,0 mIU/ml. Antibody titres were determined 2 months 
after 3rd dose.. 
High antibody titers was observed in clinical studies with children and adults. 
Results of clinical study with healthy infants vaccinated with Euvax B vaccine immunized according to the 1 
day of life, 6th week and 14th week schedule demonstrated that 95% of subjects developed anti-HBs antibody 
titers > 10 mIU/ml correlates with protection to HBV infection. The concomitant administration Euvax B 
vaccine with pertussis vaccines at 6th and 14th week do not result in immune response to Euvax B vaccine. 
Controlled studies shown that vaccination can be continued with Euvax B vaccine 10 mcg if Engerix 10 mcg 
was administered as first dose. This data concern 0, 1, 6 months schedule
