There are about 40 different potential covid vaccines already being tested on humans, with almost a hundred more at earlier stages of development in the lab. The delivery of a vaccine is seen by many as the silver bullet which could end the pandemic for good. But they are more morally complex than we might at first assume. Join us as we sift through the ethical questions around clinical trials, testing vaccines on humans, how they can be most equitably distributed, and even what material they are made with.
John has expanded on some of these ideas further, and in particular the issue of using tissue from aborted fetuses in vaccine development, in an article which you can read here.
