LAREDO, TEXAS (KGNS) -- The World Health Organization declared it's ethical to use untested drugs and vaccines in the ongoing Ebola outbreak in West Africa.
The small supply of one experimental treatment has been depleted and it could be many months until more is available.
The last of the drug is on its way to Liberia for two sick doctors.
The US company that makes it said the supply is now exhausted.
Canada said it would provide some of its experimental Ebola vaccine for use in West Africa.
The outbreak has killed over 1,000 people since March.
