There are two types of hepatitis B vaccines available: recombinant vaccines and plasma-derived vaccines. There is no difference regarding efficacy or duration of protection between the two, and they can be used interchangeably. These vaccines have been available in most countries since 1982. Each vaccine undergoes an extensive purification process, and they are effective in protecting over ninety-five percent of infants, children and young adults who are given the shot. After the age of forty, protection levels drop to ninety percent. By sixty, it falls to seventy-five percent.
