Hepatitis A Vaccine Every year hepatitis A virus affects 1.4 million people around the world and as many as 32,000 in the United States. This figure is very unfortunate because the risk of virus goes down substantially by just having access to clean water and regular hand washing. In addition, vaccine for hepatitis A is also available to stop the infection from ever happening in an individual. In short, the disease should not affect so many people worldwide because it can be prevented so easily.
What Is Hepatitis A Vaccine?
The vaccine used to stop hepatitis A virus from happening is called hepatitis A Vaccine. The vaccine is produced by using whole hepatitis A virus which is killed. Since the virus is not alive, a person cannot have hepatitis A from the vaccine. The vaccination works by helping the body in producing antibodies to fight the hepatitis A virus. These antibodies will help the body to fight off the virus in the future.
Brief Introduction of Hepatitis A
Hepatitis A virus causes the hepatitis A disease which has an impulsive start and increases abruptly and finishes in a short time. The disease is associated with bad sanitation condition, intake of unhygienic food and water and close contact with people having the disease.
Every one in five patients diagnosed with hepatitis A need hospitalization for their treatment and for every 1000 patients with the disease, 3 to 5 people will die. Diarrhea, pain in the stomach, Jaundice and flu are some indicators of the disease.
Who Should Take Hepatitis A Vaccine?
Once you have recovered from hepatitis A, the body creates antibodies to fight the infection. Thus, you will no longer need vaccination if you have had the disease.
Children
Children aged less than one year cannot be vaccinated because there is no Licensed vaccine available for them in the United States. The children between 12 to 23 months of age are advised to be vaccinated by the CDC with the hepatitis A vaccine.
Travelers
Healthy international travelers who are not older than 40 years are suggested to get hepatitis A vaccination’s first dose before traveling internationally. People who are more than 40 years old can also get an immune globulin (IG) shot in addition to the hepatitis A vaccine. The same can be given to people who have a weakened immune system and who have a chronic medical or liver condition two weeks before going on their travel. Those who do not want to get the hepatitis A vaccine because they are allergic to a component of the vaccine or a less than one year old can also opt to just get a shot of IG.
Others
The hepatitis A vaccine is supposed to be used by all those who are more than 12 months old and are at a greater risk of getting infected by the virus. Moreover, people living in a locality where the rate of disease is greater should also get vaccinated. Such people include:

The second dose provides the immunization from the disease.
TWINRIX is another vaccination available for hepatitis A. The vaccine also provides protection against Hepatitis B. It has to be administered in 3 doses and can only be given to people more than 18 years old.
All vaccines make a person immune to the virus for up to 25 years in case he is an adult and for 14 to 20 years, if the person is a child.
