In a Skype interview with VOA, Dr. Robert Klitzman, one of the co-founders of the Center for Bioethics at Columbia University in New York, said using these drugs raises ethical issues. "Does it work? What should we tell people? What if it makes people worse? We want to make sure people understand that there are risks involved. If we have a limited supply, we need to decide who should get the vaccine or medication and who should not."
Dr. Klitzman said in some sub-Saharan African languages, there's a word for "cure," but nothing that translates the word "experimental." He says anyone who receives an experimental drug has to be told it might not cure them, and if it might make the situation worse.
