Four patients in Seattle have been injected with a harmless copied genetic code from a virus in order to test out a possible vaccine. While it will still be months before we know if the vaccine is effective, scientists around the world have been fast-tracking research on COVID-19. One of the steps skipped in this trial was to see if the vaccine creates an immune response in animals, and instead went straight for the human trials. “This vaccine uses pre-existing technology. It’s been made to a very high standard, using things that we know are safe to use in people and those taking part in the trial will be very closely monitored,” commented Dr John Tregoning. The current timeline for public release, if all goes well, is around 18 months.
