Hepatitis A is the most common type of hepatitis (continued)
A vaccine, like any medicine, could possibly cause serious problems, such as a severe allergic reaction. However, the risk of hepatitis A vaccine causing serious harm, or death, is extremely small and getting a shot is much safer than getting the disease.
Some mild problems include soreness where the shot was given, headache, loss of appetite, and tiredness. Severe problems, which are very rare, would be an allergic reaction that would occur within a few minutes to a few hours of the shot. Signs of a serious allergic reaction can include difficulty breathing, hoarseness or wheezing, hives, paleness, weakness, a fast heartbeat or dizziness.
There are certain people in the community who should be routinely vaccinated with the hepatitis A vaccine. First, all children age 1, and anyone age 1 and older traveling to or working in countries with high or intermediate prevalence of hepatitis A. Some of these countries are listed at the beginning of this article, but you should consult your physician for more information.
Next, all children and adolescents 18 years of age who live in states or communities where routine vaccination has been implemented because of high disease incidences should receive the vaccine. Lastly, persons who fall within the following groups should also receive the vaccine: men who have sex with men, addicts who use street drugs, people who are treated with clotting factor concentrates and those with chronic liver disease.
There are also certain members of the population who should not receive the vaccine. First, anyone who has ever had a severe (life-threatening) allergic reaction to a previous dose of hepatitis A vaccine should not get another dose. Anyone who has a severe (life threatening) allergy to any vaccine components should not get the vaccine. Next, anyone who is moderately or severely ill at the time the shot is scheduled should probably wait until they recover. Lastly, the safety of the hepatitis A vaccine for pregnant woman has not been determined. Nevertheless, there is no evidence that it is harmful to either pregnant women or their unborn babies and the risk, if any, is thought to be very low.
It is important to note that you can only get the hepatitis A virus once and it does not lead to long-term liver problems. After it is contracted, your body builds up a defense against it. It can, as previously explained, be prevented totally if certain precautions are taken and the vaccine is received. If you meet the criteria listed above, please contact your healthcare provider to learn more.
