Hepatitis A

The hepatitis A vaccine protects against a liver infection caused by the hepatitis A virus.

• This vaccine is only available publicly funded (free) for those in the following high risk groups:

• Anyone with chronic liver disease (Hepatitis B, C).
• Those who use IV drugs.
• Men who have sex with men.
• People who have been exposed to the Hepatitis A virus through an outbreak.

• This vaccine may be recommended for others based on risk factors, however they would have to purchase it.

• 90-97% of those fully vaccinated before exposure are protected from HA.
• Studies of HA outbreaks have shown that the use of vaccine in those at risk interrupts the outbreak. The protective efficacy of vaccine in one study when vaccine was used within one week of exposure was 79%.

• At this time there are no other ways to prevent this disease.
• Practice good personal hygiene to reduce your risk. Wash your hands:

• After using the washroom
• After changing an infant/child's diaper
• Before preparing food
• Before eating
