Some people with hepatitis B will not have symptoms. For people who do, symptoms may include:

  • Yellowing of the skin and eyes ( jaundice)
  • Fatigue that lasts for weeks or even months

Children

Newborns routinely receive the first dose of the hepatitis B vaccine before leaving the hospital. Two more injections are given to all infants at:

  • 1-2 months
  • 6-18 months

Depending on the type of vaccine, some babies may receive 4 doses.

Children and teens (aged 18 years or younger) who have not been immunized as babies can also get the vaccine. For children aged 11-15 years, there is a two-dose series available, called Recombivax HB.

Adults

It is recommended that adults (aged 18 years or older) get vaccinated if they are at high risk for hepatitis B. High risk includes:

  • Having multiple sex partners
  • Getting treatment or counseling for a sexually transmitted disease (STD)
  • Being a man who has sex with other men

What Are the Risks Associated With the Hepatitis B Vaccine?

All vaccines are capable of causing serious problems, such as a severe allergic reaction.

Most people who get the hepatitis B vaccine do not have problems. Some may have mild problems, including soreness where the shot was given and fever.

Acetaminophen (eg, Tylenol) is sometimes given to reduce pain and fever that may occur after getting a vaccine. In infants, the medicine may weaken the vaccine’s effectiveness. Discuss the risks and benefits of taking acetaminophen with the doctor.
