Hepatitis B Vaccination in the Travel & Immunization Clinic for High Risk Populations

There are many ways that people can get hepatitis B. It is possible for people to have hepatitis B and not know it because they do not feel sick. That is why some people need to be tested for hepatitis B before they get the vaccine.  

If you would like to get the hepatitis B vaccine (a 3-shot series), please complete the health risk assessment first and ask yourself the following questions:

    1. Were you born in a country with moderate or highrates of hepatitis B?

      Click here and refer to table 2 (PDF)
    3. Do you live with anyone who has hepatitis B?
    4. Have you had sex with someone, male or female, who has hepatitis B?
    5. Are you a man who has had sex with men?
    6. Do you currently or have you ever injected drugs?

    If you answered yes to any of the questions, you should be tested for hepatitis B before getting the vaccine. ​​​​
