Is there a preventative vaccine for hepatitis B?
Hepatitis B infection can be prevented by getting vaccine and HBIG (hepatitis B immune globulin) soon after coming into contact with the virus. Persons who have recently been exposed to HBV should get HBIG and vaccine as soon as possible and preferably within 24 hours, but not more than 2 weeks after the exposure.
Why is there no cure for hepatitis B?
Chronic hepatitis B hasn’t been cured so far in part because current therapies have failed to destroy the viral reservoir, where the virus hides in the cell. This is in contrast to hepatitis C virus, which has no such viral reservoir and can now be cured with as little as 12 weeks of treatment.
Why is there no specific treatment for hepatitis?
No specific treatment exists for hepatitis A. Your body will clear the hepatitis A virus on its own. In most cases of hepatitis A, the liver heals within six months with no lasting damage.
Why is the official number of reported hepatitis B cases is much lower than actual infections?
The number of reported cases is much lower because many infected people do not go to the doctor because they do not have symptoms. In the U.S., approximately 1.2 million people have chronic HBV.
Why is hepatitis B vaccine recommended?
