Skunkape MD says you have been vaccinated against Hepatitis B. If you were to develop Hepatitis from an oyster, it would be more likely to be Hepatitis A. Here is the deal...Hepatitis A is spread via the fecal/oral route. It is pretty common where the folks are exposed to raw sewage;you get the idea. In most cases, Hep A is an unpleasant experience compete with fever, jaundice, GI distress, etc, but healthy folks almost always recover without longterm problems. Hepatitis B is bloodborne or spread with contact of body fluids. It is really, really, REALLY unlikely you would develop Hepatitis B from a raw oyster. Now, the real confusion with oysters and hepatitis started when the health warning signs popped-up. People who HAVE liver disease of any etiology including active Hepatitis B or C have a much harder time recovering from acute hepatitis A because it takes a huge toll on an already stressed liver. If you REALLY want to protect yourself, you can get a Hepatitis A vaccine. My official advice-You no doubt had a hepatitis panel drawn prior to your vaccination. If you were not told you have Hep C, and you are now vaccinated against Hep B, eat as many oysters as you can get your hands on! They are safe!
