In 2018, CDC in the USA recorded 3,322 cases of acute hepatitis B with an overall incidence rate of 1.0 cases per 100,000 American population.

Who Should Get The Hepatitis B Vaccine?

The Advisory Committee on Immunization Practices (ACIP) recommends that all infants and people with several conditions receive hepatitis B vaccination.


The CDC recommends that children should receive their first hepatitis B vaccine at birth. By the age of 6 to 18, the CDC recommends all children complete their vaccination doses. Children who didn’t get their vaccination at birth or up to 19 years old should also take the vaccine. Hepatitis B vaccination is one of the requirements of many schools in the U.S. during school admission.


The CDC recommends that all adults at risk for HBV infection must take the hepatitis B vaccine. These people include-

  • People with chronic liver or kidney diseases
  • People with more than one sex companion
  • Sex partners with HBV infection
  • People who use street drugs
  • Men with male sexual partners
  • People with exposure to human blood due to work
  • Kidney dialysis patients
  • People who frequently travel, especially to places with HBV spreading
  • people with HIV infection
  • kidney dialysis patients

However, you can also take vaccines whether or not you have these reasons. In addition, Pregnant women can take the vaccine at the brisk of HBV spreading; there is no acute danger in taking the vaccine for them.

Who Should Not Get The Hepatitis B Vaccine?

Though the CDC recommends all unvaccinated adults take the shots, people with few conditions are there who can not take the vaccine.

  • People with a life-threatening allergy or allergic to the components of the vaccine
  • People with a life-threatening reaction to the previous dose
  • People with severe illness during the scheduled shots of the vaccine

The Licensed Hepatitis B Vaccines

Three single-antigen vaccines and two combination vaccines are licensed in the United States currently. The single-antigen hepatitis B vaccines are-


The Combination vaccines are-

PEDIARIX®: combined hepatitis B, diphtheria, tetanus, acellular pertussis (DTaP), and inactivated poliovirus (IPV) vaccine.

It must be administered after age six weeks or before age seven years.

TWINRIX®: Combined Hepatitis A and hepatitis B vaccine. It is recommended for people below or equal to 18 years who are at increased risk for HAV and HBV infections.

When and How You Should Take The Vaccine?

The hepatitis B vaccine protects people from HBV infection. When you get the vaccine, your body creates active immunity and develops antibodies against the hepatitis B virus. You need to take the hepatitis B vaccine as a series of 2, 3, or 4 shots (injection). Usually, the shots are given in the upper arm or leg to provide long-lasting immunity.

For infants and children, all babies need to take three doses:

  • The time between the first and second shot should be at least one month.
  • The second and third shots should be at least two months gap. Ideally, they should be at least four months.
  • At least four months should pass between the first and third shots.
  • Premature babies may need a fourth shot.

Suppose the vaccination series is discontinued and the spacing between doses is more prolonged than recommended. In that case, it is not necessary to start the series over or add more quantities. The series should be completed from where it was disrupted.

How Helpful Is The Vaccine?

The hepatitis B vaccine provides long-term protection from hepatitis B infection, possibly life-long. Research of 2016 suggests vaccines protect those who had started the hepatitis B vaccination before they were six months old for at least 30 long years against HBV infection.

Hepatitis B Vaccine: How Long Does It Last?

As mentioned above, the vaccines’ protection lasts for at least 30 years among healthy people who started vaccination at six months of age. The vaccines work perfectly against clinical illness and chronic hepatitis B virus infections. Most importantly, your active immunity persists even if your antibody level may decrease detectably.

Interrupted Dose

Suppose you have missed your dose, or there is an interruption between doses. Now, what is the hepatitis b vaccine schedule for adults’ missed doses? Does the vaccine series need to be restarted? To simply answer, NO. You do not need to restart your vaccination all over again. However, there are few things that you should follow-

  • If your vaccine series interrupts after the first dose, the second dose should be administered as soon as possible.
  • The second and third doses should be distributed over at least eight weeks.
  • If only the third dose is interrupted, it should be administered as soon as possible.

Hepatitis B Vaccine: Side Effects

Usually, there are no significant side effects recorded due to hepatitis B vaccination. Maximum patients encounter a sore arm from the injection site. However, every individual is unique, and so is his response. SO, you may face some mild consequences that include-

  • Headache
