It is always a good idea to get screened for Hepatitis A or B antibodies before you get vaccinated to make sure you aren't already infected. Any health provider should be able to screen you or provide you with the vaccines. Some clinics will only vaccinate you if you are a certain age, if you ask, or if you are a regular patient. If you do not have a regular health provider or are having trouble finding one who will vaccinate you, you can ask your local city or county health department where to go. You can also call the National Hepatitis Hotline at 1-800-465-4837.
