Hepatitis A vaccine

Monday, June 18, 2018

    We have received numerous requests asking about the Hepatitis A. Hepatitis A is a vaccine-preventable, communicable disease of the liver caused by the hepatitis A virus (HAV). It is usually transmitted person-to-person through the fecal-oral route or consumption of contaminated food or water. It is a self-limited disease that does not result in chronic infection. Antibodies produced in response to hepatitis A infection last for life and protect against reinfection. Among older children and adults, infection is typically symptomatic. Symptoms usually occur abruptly and can include the following:



            - Fever

            - Fatigue

            - Loss of appetite

            - Nausea

            - Vomiting

            - Abdominal pain

            - Dark urine

            - Clay-colored stools

            - Joint pain

            - Jaundice (yellowing of the skin and eyes)


              Seventy percent of infections in children younger than age 6 are not accompanied by symptoms. When symptoms are present, young children typically do not have jaundice.



                The Advisory Committee on Immunization Practices (ACIP) recommends hepatitis A vaccination for the following people:

              •      - All children at age 1 year 
              •      - Travelers to countries where hepatitis A is common
                •      - Family and caregivers of adoptees from countries where hepatitis A is common
                •      - Men who have sexual encounters with other men
                •      - Users of recreational drugs, whether injected or not
                •      - People with chronic or long-term liver disease, including hepatitis B or hepatitis C
                •      - People with clotting-factor disorders
                •      - People with direct contact with others who have hepatitis A
                •      - Any person wishing to obtain immunity (protection)

              • The best way to prevent hepatitis A infection is to get vaccinated.
