A Vaccine for Leprosy

Prophylactic or Therapeutic Vaccine Options

A potential leprosy vaccine can be either prophylactic (preexposure) or therapeutic (postexposure). Dr. Tom Gillis, Chief of the National Hansen’s Disease Programs Lab Research, remarks that it is not necessarily easier to create either version of the vaccine. However, in America, because of the low incidence of leprosy, it makes much more sense to focus on a therapeutic vaccine to administer only to those who are actually affected by the disease.
