Hepatitis B for Adults

Hepatitis B is a viral infection that primarily affects the liver and can lead to serious health complications if left untreated. It is estimated that there are over 2 billion individuals worldwide with serologic evidence of hepatitis B virus (HBV) infection. In fact, chronic hepatitis B infection is responsible for approximately 887,000 deaths each year due to associated cirrhosis and hepatocellular carcinoma. The good news is that hepatitis B can be prevented through vaccination, making it crucial for adults to understand the importance of getting immunized.

The Need for Hepatitis B Vaccination

Vaccination plays a vital role in preventing the spread of hepatitis B and reducing the burden of this infectious disease. The global coverage for hepatitis B vaccination in infants has significantly increased over the years, from 3 percent in 1992 to 85 percent in 2019. However, there is still room for improvement, as even in countries with universal vaccination programs, coverage rates may fall short of 100 percent.

In the United States, hepatitis B vaccination coverage among adults remains low, with approximately 25.8 percent of adults aged 19 and older receiving the recommended three doses of the conventional hepatitis B vaccine. This is concerning, considering the potential for severe complications, such as liver cancer and cirrhosis, associated with chronic hepatitis B infection. It is crucial for adults to understand that hepatitis B vaccination is a key preventive measure to protect themselves and others from this potentially life-threatening infection.

Hepatitis B Vaccination Schedule for Adults

The hepatitis B vaccination schedule for adults varies depending on the specific vaccine used. There are three primary hepatitis B vaccines available in the United States, as well as three combination vaccines that provide protection against other diseases in addition to hepatitis B.

For infants, it is recommended to receive the first dose of the hepatitis B vaccine within 24 hours of birth, followed by the second dose at 1 to 2 months, and the third dose at 6 to 18 months. However, if the initial dose was missed at birth, it is important to start the series as soon as possible.

Children and adolescents should receive a total of three doses of the hepatitis B vaccine, with the option of receiving four doses if a combination vaccine is used. Adolescents between 11 and 15 years of age who did not receive the vaccine when younger may be able to complete the series with two doses of a specific type of hepatitis B vaccine.

Adults aged 19 to 59 years are recommended to receive hepatitis B vaccination, and the number of doses depends on the specific vaccine used. Heplisav-B is a two-dose vaccine series approved for individuals 18 years of age and older. Other hepatitis B vaccines typically require three to four doses. It is important for individuals to consult with their healthcare provider to determine the most appropriate vaccine and dosage for their specific situation.

Identifying High-Risk Individuals

While hepatitis B vaccination is recommended for all adults, certain individuals are considered to be at higher risk for hepatitis B infection. Identifying these high-risk individuals is crucial for targeted vaccination efforts. Some of the risk factors for hepatitis B include:

Sexual exposure: Individuals who have sexual contact with someone who is hepatitis B surface antigen (HBsAg)-positive or engage in unprotected sex with multiple partners are at an increased risk.
Injection drug use: Sharing needles, syringes, or other drug-injection equipment significantly increases the risk of hepatitis B transmission.
Household contacts: Living with someone who is HBsAg-positive can put individuals at risk of infection.
Healthcare and public safety workers: Occupational exposure to blood or body fluids can pose a risk of hepatitis B transmission.
Individuals with chronic liver disease: People with chronic liver conditions, such as cirrhosis or hepatitis C infection, are more susceptible to hepatitis B infection and should be vaccinated.
Travelers to high-risk regions: Individuals traveling to areas with high rates of hepatitis B should consider vaccination to protect themselves from potential exposure.
Men who have sex with men (MSM): This population is at an increased risk of hepatitis B transmission and should be vaccinated.
People with HIV infection: Individuals with HIV are more susceptible to hepatitis B infection and should receive vaccination as part of their overall healthcare management.
People with diabetes: The risk of hepatitis B infection is higher among individuals with diabetes, particularly those aged 19 to 59 years. Vaccination should be considered for this population.
Others: Individuals seeking evaluation or treatment for sexually transmitted infections, those with a history of injection drug use, and incarcerated individuals should also be considered for hepatitis B vaccination.

It is important to note that eligibility for hepatitis B vaccination is not restricted to individuals who identify specific risk factors. Any adult who wants to protect themselves from hepatitis B should consider vaccination.

Hepatitis B Vaccine Safety and Side Effects

Hepatitis B vaccines have been extensively studied and are considered safe and effective. More than 1 billion doses of the vaccine have been administered worldwide, with no evidence of causing severe adverse effects.

Common side effects of hepatitis B vaccination include soreness, redness, or swelling at the injection site. These effects are typically mild and short-lived. Severe allergic reactions are rare but can occur. It is important for individuals to discuss any concerns or potential allergies with their healthcare provider before receiving the vaccine.

The Importance of Hepatitis B Vaccination in Public Health

Hepatitis B vaccination is a critical component of public health efforts to prevent the spread of this infectious disease. Achieving high vaccination coverage rates is essential to reduce the incidence of acute and chronic hepatitis B infections and associated complications.

By vaccinating infants, children, adolescents, and adults, we can create a protective barrier against the transmission of hepatitis B within communities. This not only safeguards individuals from the potential health consequences of hepatitis B but also helps to limit the overall burden of the disease.

To initiate the evaluation process, it is prudent to consider and undergoing a comprehensive test.

Conclusion

Hepatitis B is a serious viral infection that can have long-term health consequences if left untreated. Vaccination is the most effective way to prevent hepatitis B infection and its associated complications. It is crucial for adults to understand the importance of hepatitis B vaccination and to identify their risk factors for infection.

By following the recommended vaccination schedule and ensuring high coverage rates, we can work towards the goal of eradicating hepatitis B globally. Protecting ourselves and our communities from this potentially life-threatening infection is a shared responsibility, and vaccination is a vital tool in achieving this goal. Consult with your healthcare provider to determine the most appropriate hepatitis B vaccination approach for your individual needs and circumstances.

Remember, by taking action and getting vaccinated, you are not only protecting yourself but also contributing to the collective effort of creating a healthier and safer world. Let’s prioritize hepatitis B vaccination and work towards a future free from this preventable disease.
