What Are the Options for Hepatitis Vaccines?

Hepatitis A and B are the most widely recognized hepatitis viruses, and fortunately, both have effective vaccines available for people up to 59 years old. As health guidelines evolve, access to these vaccines is expanding, offering more protection to at-risk populations.

According to Jeff Goad, PharmD, and President of the National Foundation for Infectious Diseases, there are actually two types of vaccines for Hepatitis A: Havrix and Vaqta. Both boast over 95% efficacy after just two doses, providing immunity that can last over two decades. For Hepatitis B, three vaccines are on the market: the traditional recombinant vaccines, Engerix-B and Recombivax, alongside a newer option, Heplisav-B. There's even a combo vaccine called Twinrix that protects against both Hepatitis A and B, though it's specifically for adults.

Understanding Hepatitis: The Basics

So, just what is hepatitis? In essence, it’s liver inflammation typically triggered by viral infections, specifically Hepatitis A, B, and C. Chronic hepatitis can lead to dire consequences such as liver failure, cirrhosis, or even liver cancer. While Hepatitis A is usually acute and doesn't become chronic, it can still result in symptoms like jaundice and severe fatigue.

Diving Deeper: Types of Hepatitis and Their Vaccines

There are five primary types of hepatitis: A, B, C, D, and E, with Hepatitis A and B being preventable through vaccines. Hepatitis A spreads primarily through contaminated food and water, while Hepatitis B is bloodborne and sexually transmitted. Hepatitis C currently lacks a vaccine, while D only affects those already infected with B. Hepatitis E, typically passed through water, is quite rare in the U.S.

Who Should Get Vaccinated?

Vaccine recommendations hinge on different risk factors, including behavior, occupation, and geography. For instance, healthcare workers are advised to get immunized against Hepatitis B, while travelers heading to regions where Hepatitis A is prevalent should consider getting that vaccine as a precaution.

The Importance of Early Vaccination

Vaccination strategies for Hepatitis A and B start early. Hepatitis A vaccines are recommended starting at age one, while Hepatitis B vaccines can begin at birth. Notably, the CDC now advises that individuals up to age 59 should get vaccinated for Hepatitis B for enhanced protection. This change stems from findings that certain populations, particularly those with diabetes or health workers, face higher risks.

Stay Informed and Protected!

It's essential to stay up-to-date with your vaccinations, especially in a world where viral infections can have severe health implications. With Hepatitis A and B vaccines proving to be safe and effective, ensuring you and your family are protected should be a priority.

As we highlight the significance of Viral Hepatitis Awareness Month, now is the perfect time to educate yourself further and consult health professionals about your family's vaccination needs.
