A Phase 1 clinical trial to test the safety and effectiveness of a potential vaccine for the new coronavirus is currently underway in Seattle. Even still, a vaccine is likely a year away, at minimum, from being available to the public.
Why does it take so long?
A vaccine will need to be tested in months-long clinical trials to determine its safety and effectiveness in people, explained Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health. If the vaccine proves safe and effective in the trials and is rushed through regulatory processes, it will still need to be produced for the masses, which will likely add several more months to the timeline.
