$INO Hmmmm...ethical or unethical? You decide. In these tightly-controlled trials, volunteers are given a vaccine and then about a month later are deliberately infected with the disease under controlled conditions. They are then isolated in a quarantine facility and monitored to see if they become sick or if the vaccine protects them. Critics say deliberately infecting someone with a potentially deadly disease for which there is currently no effective treatment is unethical. Leading vaccine developers AstraZeneca , Sanofi, BioNTech, Moderna and Inovio said last month that their respective vaccine candidates were not involved in the program. Hmmmmm...Johnson & Johnson has previously said it was evaluating the potential benefit of such trials. metro.us/britain-moves-clos...
