The Hep B vaccine is used to help prevent serious effects brought on by exposure to hepatitis B. Hepatitis B is a very serious condition that causes damage to the liver. The vaccine is an inactive type immunization, which means the vaccine is made with inactive viruses. The inactive virus is not strong enough to cause the disease in those who take the vaccine, but it is potent enough to produce an immune to the virus. Some people still develop hepatitis even after taking the vaccination, this is due to the fact no immunization is 100 percent effective. These vaccines are usually 95 to 98 percent effective in reducing the chances of developing hepatitis.
There are usually no major side effects from taking the Hep B vaccination. Some people have complained of having soreness in the arm at the injection site. Some people experience a mild fever as well. Those who have major problems with the vaccine are due to an allergic reaction.
It is important to take certain factors into account before taking the Hep B vaccine. Individuals suffering from and upper respiratory infection should delay having the vaccine. For people who are allergic to yeast this immunization should not be given to them. The vaccine contains subtrates that are very similar to yeast. People who are infected with AIDS or other immune compromising illnesses should not have the vaccine either because it will pose a serious threat to their health. If a person does experience an allergic reaction after the injection, there should not be any further doses given. The advice of a health care professional should be contacted for alternative methods for the vaccine. Individuals interested in taking the Hep B vaccine should contact their health care provider to set up an appointment to find out if they are a good candidate for it.
