Hepatitis A is virus that causes acute liver disease. Hepatitis A can be mild and only last a few weeks or more severe with infections lasting up to a few months. Almost all cases of hepatitis A have resolved within 6 months or less. Although Hepatitis A does not become chronic like other hepatitis infections, it’s still an infection that must be taken seriously., as it can wreak havoc on the liver and there are serious complications that can results from a hepatitis A infection. Currently, hepatitis A infections are decreasing in the United States, although hepatitis A is prevalent in other parts of the world such as Eastern Europe, Africa, Central America, South America, Asia, and Mexico. If someone plans to travel to those parts of the world, there is a hepatitis A vaccine that is highly recommended.
There are several vaccines available to prevent people from catching Hepatitis A. The first one is called Havrix. It contains aluminum hydroxide, which is an adjuvant, and viral antigen. Another vaccine is called Twinrix. Twinrix is a combination vaccine that prevents both Hepatitis A and Hepatitis B. A third common vaccine for Hepatitis A is called Vaqta. Vaqta contains an inactive whole virus. All three of these vaccines are effective at preventing people from becoming infected with Hepatitis A.
