Enhancing Healthcare Team Outcomes

The interprofessional health care team faces many challenges when vaccinating patients for hepatitis B. While few medical interventions have as significant an impact on health as vaccinations, and the hepatitis B vaccination is generally safe, lack of knowledge about the vaccine by healthcare team members and patient concern about adverse events can decrease coverage. Challenges on knowledge of the vaccine for healthcare team members include staying current on evolving recommendations for whom the vaccine is indicated. All team members can increase the vaccination rate of their patients by encouraging all staff to become trained in the assessment of vaccination histories and any pertinent staff in the administration of the vaccine. Protecting the time available for the team to do this is an essential component of this strategy. All patients should receive education on the benefits of vaccination, including its herd immunity effect, the generally safe side effect profile, and the relatively few contraindications. A presumption of acceptance may be effective with most patients. The hesitant parent and patient who does not respond to this can pose a challenge in vaccination. Motivational interviewing techniques have shown to be effective with these hesitant patients.

  • Discontinuation of anti-hepatitis B therapy, including VEMLIDY, may result in severe acute exacerbations of hepatitis B.

What Are The Different Types Of Hepatitis

Hepatitis is a global concern. The World Health Organization estimates that 354 million people globally live with hepatitis B or C, the types most responsible for chronic liver disease in the form of cirrhosis, cancer and hepatitis.

The five primary strains of the virus that lead to hepatitis are labeled as types A, B, C, D and E. These strains are identified by the differences in their transmission, severity, geography and prevention.

Five types of hepatitis:

The Centers for Disease Control and Prevention reports that Hepatitis A, B and C are the most common strains in the United States. The best way to prevent hepatitis A and B is through vaccination. Chronic hep B, hep C and hep D infection can lead to long-term liver damage, cirrhosis of the liver, or liver cancer.

Difference Between Hep A And Hep B Vaccines

The Truth about Hepatitis B

In the United States, the hep A shot is administered routinely to very young children. It may be given in one or two doses. If the child is getting two doses, the first one should be no later than 12 months of age. There is some flexibility in the interval between shots, but six to 18 months is common.

The hep B vaccine should be given to all babies as soon as possible after birth. After the first dose, two or three doses follow with an interval of at least four weeks. Unvaccinated adults get three doses spanning six months. If you are at least 18 years old, you have the option to get a combination vaccine. The dual vaccine is given in three shots over six months.

Adults traveling to areas with a high rate of HAV would benefit from getting the hep A shot. Talk to your physician about your risk for hep A and hep B to determine if you should receive the vaccines. You can schedule your hepatitis vaccine with your primary care physician or one of your local pharmacies, such as CVS and Walgreens.
