hepatitis vaccines

Hepatitis vaccines protect against viruses that cause liver infections—mainly hepatitis A and B. The hepatitis A vaccine is given in two doses and prevents illness from contaminated food or water. The hepatitis B vaccine is usually given in three doses and prevents infection through contact with infected blood or bodily fluids. Both vaccines boost your immune system to recognize and fight the virus if exposed. Getting vaccinated is an effective way to prevent serious liver damage, chronic illness, or transmission to others. These vaccines are safe, routinely recommended, and have significantly reduced hepatitis-related health problems worldwide.
