Hepatitis B vaccine types
As of the moment, there are 3 Hepatitis B vaccines available in the market; Engerix-B manufactured by GlaxoSmithKline, Recombivax HB from pharmaceutical giant Merck, and Heplisav-B which was only approved in 2017 from Dynavax. The first two vaccine brands follow the three-dose schedule, while Heplisav-B is the first Hepatitis B vaccine that has a two-dose immunization schedule.
Immunization schedule for Hepatitis B
- Three-Dose Hepatitis B Vaccine. Engerix-B and Recombivax HB follow a method that is commonly known as a 0-1-6-month schedule. This means that:
- (0) The first dose is given anytime. If the patient is a newborn, the dose should be given at once in the delivery room.
- (1) The second dose is one month after the first dose.
- (6) The last dose is 5 months after your first dose. Some doctors allow giving the last dose as early as 4 months or 16 weeks after the first dose if, for example, the patient really needs to be protected as soon as possible due to travel or exposure to Hepatitis B (student nurses or doctors). However, if the patient is a newborn, a strict rule to wait until the baby is 6 months’ old is needed for the third and last dose to be given.
- Two-dose Hepatitis B Vaccine. Heplisav-B is the newest hepatitis B vaccine approved by the FDA and is scheduled to be given 1 month apart.
- Alternate Hepatitis B Vaccine Schedule for Adolescents. Recombivax HB can also be given to teens ages 11 to 15, however, their dose ifs lessened. Instead of getting 3 doses, they are only given 2 doses that should be administered 4 to 6 months apart.
