What are Hepatitis B vaccine names?

Engerix-B Hepatitis B VaccineThe first hepatitis B vaccine was approved in the United States in 1982, but it is no longer used. In 1986 and 1989, two other hepatitis B vaccines were created using recombinant DNA technology:

There are also a few other combination vaccines against Hepatitis B that also contain vaccines against other diseases, including:

  • Pediarix® (HepB-DTaP/IPV)
  • Twinrix® (HepB-HepA) 
  • Comvax® (discontinued in 2014)

How is the vaccine given?

Engerix-B® and Recombivax HB® are given in 3 or 4 shots over a 6-month period. Infants should get their first dose at birth and usually complete the series by 6 months of age. Older children and teenagers who were not vaccinated as infants should also be vaccinated, as well as unvaccinated adults who are at risk of infection with hepatitis B.

Can the vaccine cause Hepatitis B?

No. Engerix-B® and Recombivax HB® are recombinant vaccines. That means they only contain parts of the hepatitis B virus and they can’t cause an infection. They are made by putting the gene for hepatitis B into a common yeast and harvesting pieces of the virus.

Is the hepatitis B vaccine safe?

Yes. Since 1982, at least 50 million infants and over 70 million teenagers and adults have received at least one Hepatitis B vaccine. The risk of serious side effects is very low and most children who get the hepatitis B vaccine do not have any side effects at all.

What are common side effects?

Of the children who have side effect of the hepatitis B vaccine, the most common is mild soreness where the shot was injected or a low fever. Adults are slightly more likely to experience these side effects.

The common side effects of Engerix-B® and Recombivax HB® include:

  • Injection-site soreness, swelling, redness, or lump
  • Fatigue
  • Fever
  • Irritability
  • Diarrhea
  • Loss of appetite

Hepatitis B vaccination may cause apnea (temporarily stop breathing) in infants who are premature, low birth weight, or sick. Delayed vaccination may be recommended on a case-by-case basis.

What are severe side effects?
