A local, licensed medical doctor or an authorized health care professional can administer the hepatitis B vaccine, according to the Mayo Clinic. As of 2015, there are four main brands of the vaccine that doctors in the United States can administer: Engerix-B, Engerix-B Pediatric, Recombivax HB and Recombivax HB PedatricAdolescent.
The hepatitis B vaccine is administered by healthcare professionals to infants, adolescents and unvaccinated adults. The vaccine is typically administered by three to four injections over a 6-month period, according to Vaccines.gov. Children should get their first dose of the hepatitis B vaccine at birth, since babies are at a much greater risk of developing chronic infection if they come in contact with the virus. Babies should complete the series between 6 and 18 months of age.
Children and adolescents under the age of 19 who have not already received the hepatitis B vaccine should also be vaccinated, according to Vaccines.gov. Children or adolescents with missed shots in the series receive what is known as a “catch-up vaccination.” Unvaccinated adults who have HIV, people with chronic liver disease and health care workers at risk of blood exposure should also get the vaccine. Adults who are sexually active with multiple partners, those in close contact with someone with hepatitis B, and people who share needles, syringes or other drug equipment also need the vaccination.
