Past research is helping speed up the search for a COVID-19 vaccine, but the approval process will probably still take 18 months to 2 years. Experts note that potential vaccines still need to go through a rigorous three-phase clinical trial process. Experts add that it’s important for the scientific community to “underpromise and overdeliver” on COVID-19 vaccines so they don’t raise the public’s hopes prematurely.
