The primary vaccine for hepatitis B was launched worldwide within the early Eighties, and childhood vaccination grew to become routine within the U.S. beginning within the early Nineteen Nineties. The vaccine is extremely efficient at stopping hepatitis B, and following its introduction the speed of recent circumstances steadily dropped within the U.S. However extra not too long ago, the incidence of hepatitis B has stayed steady, if low. And although U.S.-born youngsters are broadly shielded from it, there are a lot of residents born in international locations the place vaccination is much less widespread, in addition to older adults who could have by no means gotten vaccinated in any respect (the CDC recommends that folks as previous as 59 ought to get the vaccine).
