Hepatitis A vaccine

Article Abstract:

A US-approved vaccine to prevent hepatitis A appears to be safe and effective. Hepatitis A is a viral disease that is spread by consuming fecally-contaminated food or water or by direct fecal-oral contact. As people in the US age, they are increasingly likely to acquire hepatitis A infection and to develop immunity. As of mid-1995, a product called Havrix is the only hepatitis A vaccine available in the US. It is administered in .5 milliliter (ml) or 1 ml doses injected on two or three occasions. At least 80% of adults develop a protective immune response within 15 days after the first injection. A clinical study revealed that the vaccine was 90% effective and antibody levels suggest that protection will extend for approximately 10 years. Severe allergic reactions, headache, fever, nausea, and loss of appetite are rare side effects.
