Hep A Vaccine details, schedule and side effects

Summary: Hep A vaccine should be taken by people who are prone to get the virus, especially people who are traveling and people who are visiting or living in high risk areas.

Hep A vaccine or hepatitis A vaccine is a vaccine developed to counter the effects of the Hepatitis A virus. The vaccine was first successfully developed at Merck by Maurice Hilleman. Merck is one of the largest pharmaceutical companies in the world and was established in 1891. They can be credited with creating the hepatitis A vaccine. The vaccine is very successful, shown to be effective in more than 95% of the cases. The effects of the vaccine are long-lasting and can last for more than a decade. An inactivated Hepatitis A virus is injected into the system and this provides long term immunity.


The hep A vaccine was first used around 1996 on children living in areas that had a high risk of hepatitis A. Hepatitis A is a very common disease found in many parts of the world and is especially prevalent in poor countries with low standards of hygiene. The virus is most commonly spread through fecal contamination where the virus gets into food or water supply. In 1999, the use of the vaccine also spread to lower risk areas and today, it is recommended in the U.S. for all children around the age of 12 to 13 in a bid to eliminate the virus from the world totally.

People who travel are also advised to get the hep A vaccine. Hepatitis A is preventable and all it takes is a vaccine.

Geographical regions where the virus is prone to be present are Eastern Europe, the far eastern countries, Latin America, Central America, Africa and India.


The hep A vaccine should be injected in the muscle of the upper arm in two doses for maximum effect. An initial dose should be given followed by a secondary dose a year or six months later. The vaccine will come into effect 2 to 4 weeks after injection and effects can last for up to ten years.
