Coronavirus Vaccine Will Be A 'Dimmer Switch,' Researcher Says
Large populations of susceptible or at-risk people need to be studied in order to gauge the safety and efficacy of a coronavirus vaccine, says Dr. Richard Kennedy of the Mayo Clinic.

No one really knows when a vaccine will become available. President Trump has said a vaccine could be ready by November. Dr. Anthony Fauci said we may have one by early next year, while some scientists and researchers say more time is needed than that.
