What is hepatitis B? Hepatitis B is a liver disease that makes your liver swell and stops it from working right. The liver does many things to keep you alive. The liver fights infections and stops bleeding. It removes drugs and other poisons from your blood. The liver also stores energy for when you need it.
What is the hepatitis B shot? The hepatitis B vaccine is given through three shots. The CDC recommends that all babies get the vaccine. Infants get the first shot within 12 hours after birth. They get the second shot at age 1 to 2 months and the third shot between ages 6 and 18 months.
Who should not receive the vaccine? A serious allergic reaction to a prior dose of hepatitis B vaccine or a vaccine component is a contraindication to further doses of hepatitis b vaccine. The recombinant vaccines that are licensed for use in the United States are synthesized by Saccharomyces cerevisiae (common bakers' yeast), into which a plasmid containing the gene for HBsAg has been inserted. Purified HBsAg is obtained by lysing the yeast cells and separating HBsAg from the yeast components by biochemical and biophysical techniques. Persons allergic to yeast should not be vaccinated with vaccines containing yeast.
What if you suffer a side effect from the vaccine? You may be eligible to bring a claim under the National Vaccine Injury Compensation Program. Learn more here.
