Leprosy Vaccine

An effective leprosy vaccine will save children like Marc Jun from a lifetime of suffering with this dreaded disease.

American Leprosy Missions is committed to bringing an END to leprosy by developing a leprosy vaccine that will stop this terrible disease before it even starts.

So in 2002, American Leprosy Missions began a partnership with the Infectious Disease Research Institute (IDRI) in Seattle, Washington to develop a vaccine for leprosy.

This investment of 15 years and $5.1 million has resulted in a vaccine that is now ready for Phase I clinical safety trials in healthy human volunteers.

This is an exciting opportunity to partner with us to make a lasting difference in the world by opening the door to finally stopping this devastating disease.

Why is a leprosy vaccine needed?

  • This ancient disease is still disabling and isolating people.
  • Every two minutes someone is diagnosed with leprosy.
  • More than four million people in the world suffer from leprosy-related disabilities.
  • An effective vaccine will limit infection, prevent disease and reduce transmission.
  • A vaccine is the only way to end this terrible disease.

What is the current status of the leprosy vaccine?

Thanks to the generous support of people like you, a leprosy vaccine has been developed and manufactured in a large enough quantity for further testing. Toxicology studies are complete, and now the vaccine is ready for the Phase I clinical trial (safety study in healthy human volunteers).

We are ready to sign an agreement with the Phase I clinical trial site and finally start this exciting part of the leprosy vaccine process.

The leprosy vaccine has been developed and manufactured. Now it’s ready for the Phase I clinical trial.

Why now?

  • This is the first leprosy-specific vaccine to go through Phase I clinical trials.
  • We believe this vaccine will be an exciting new way to stop the transmission of leprosy and the only way to protect people from the disease long term.
  • What’s more, the vaccine may protect against nerve damage, the most serious complication of leprosy.
  • The vaccine is manufactured and just waiting to be tested.
  • A Phase I clinical trial site has been selected and has scheduled the testing.

Why you?

  • This is an historic opportunity to help end an ancient disease.
  • With your help, families will never have to hear the devastating news that they have leprosy, nor suffer its debilitating effects.
  • You can leave a lasting legacy for millions of people around the world.

Funds needed

Thanks to your generous support, we have raised $785,708 of the $1,206,501 needed for the leprosy vaccine Phase I clinical trial. This is enough for us to move forward!

And the next exciting milestone has already been reached: The vaccine has received approval from the U.S. Food and Drug Administration.

This vaccine may be the most exciting breakthrough in leprosy treatment since the cure, multi-drug therapy, was launched in the 1980s.

Together we have reached this historic moment. Thank you!

If you’d like to contribute to the leprosy vaccine, we still need $420,793 in order to finish the Phase I clinical trial. Donate now.
