Do I need to be tested for hepatitis A before getting the vaccination?
Your provider may decide to test your blood for antibodies to hepatitis A but this is not mandatory for everyone. If you have antibodies to hepatitis A already, it means either that you were infected with hepatitis A in the past or that you were previously vaccinated against hepatitis A. Either way, you don't need to get the hepatitis A vaccination if you already have antibodies to hepatitis A.
