Because hepatitis delta requires someone to also have hepatitis B, the best way to prevent an infection is by getting the hepatitis B vaccine series. Family members and sexual partners of people with hepatitis B and delta are high-risk and should be vaccinated.
- The hepatitis B vaccine is a series of 2 to 3 shots usually given over a 6-month period and is available at a doctor’s office, health department or STD clinic. If you live in the US, click here to find a vaccine location near you.
