As mentioned earlier, the vaccine for Hepatitis B is part of the preventive aspect of the disease. What the vaccines have is the envelope proteins of the Hepatitis B Virus as well as the HBsAg or the Hepatitis B surface antigen. These components of the vaccine are derived from the yeast cells in which there is an inserted HBsAg genetic code. There are a total of three shots that are given to the recipient of the vaccine. The first two vaccines are being given with one month interval. The last dose is then introduced to the body six months after the first dose has been injected.
The invention of the vaccine for Hepatitis B was pioneered by Alfred Prince in the year 1968. Prince is a virologist by his profession. Together with the help of Hilleman, they have used three main treatments. These are formaldehyde, urea as well as pepsin. This was used in blood serum that underwent rigorous filtration. This was done in order to come up with the safe vaccine for the case. The use of the made vaccine was licensed in the year 1981 by FDA. When it comes to its demand in the market, this was not really successful. This is because of the fact that the vaccine is the product of blood serum from human. During the time of Pablo DT Valenzuela who is the research director of the 1986 Chiron Corporation, the vaccine was withdrawn from the market. By that time, the first recombinant was developed and it is now the one being used as of the moment.
There are some groups of population who are recommended to undergo Hepatitis B vaccination. Examples of these are the babies who are a product of a parent that is affected by Hepatitis B. Particularly, these babies are being given the vaccine in order to reduce the possibility of transmitting the infection. The vaccine must be given to the baby within the first 48 hours of birth.
To those who will undergo the vaccination, there is usually a blood test that is being conducted after the first to fourth month from the primary course of the vaccine. This is done in order to determine if there is proper response to the vaccination. The protection rate success that is expected is about 85% to 90%. As mentioned, there is just a specific year when you will be protected by the vaccine. Once the protective time is already finished, you must receive booster dose. Yet, there is no need for you to undergo retesting when you will receive this booster dose. The poor response to the vaccination is reported to happen in people who are smoking, obese and are at the age of 40 and above.
