Hepatitis B is a common disease in the United States. The good news is that the hepatitis B vaccine gives more than 90% protection to people who get the vaccine.
According to the CDC, symptoms may include:
- Fever
- Feeling tired
- Upset stomach and throwing up
- Not feeling hungry
- Dark urine
- Pain in the muscles, joints, and stomach
- Jaundice (yellow skin or eyes)
Acute hepatitis B symptoms usually last a few weeks — but they can last as long as 6 months.
If the acute hepatitis B infection does not go away after 6 months, it’s considered a chronic hepatitis B infection. Most people who have chronic hepatitis B don’t have symptoms at first. But chronic hepatitis B is a lifelong illness that can lead to serious — and possibly deadly — liver problems, like:
- Cirrhosis (scarring of the liver)
- Liver cancer
- Liver failure
Hepatitis B spreads through blood, or other body fluids. Hepatitis B can spread from mother to child during birth — and when someone:
- Has sex with a person who has hepatitis B
- Shares drug needles with a person who has hepatitis B
- Shares a razor or toothbrush with a person who has hepatitis B
- Touches the blood or open sores of a person who has hepatitis B
Who should not get the Hepatitis B Vaccine?
Some people should not get the hepatitis B vaccine — or may need to wait to get it. Be sure to tell your doctor before getting vaccinated if you:
- Have had a life-threatening allergic reaction to the hepatitis A vaccine or any ingredient in the vaccine
- Are sick
