    As we get closer to a COVID-19 vaccine, it’s exciting to imagine a day when the virus is gone. But a vaccine will not be a magic bullet. In fact, it may be only about 50% effective.

    Dr. Anthony Fauci, chief of the National Institute of Health and Infectious Disease, has tried to set realistic expectations when discussing the importance of a vaccine. “We don’t know yet what the efficacy might be. We don’t know if it will be 50% or 60%,” Fauci said during a Brown University event in August.

    “I’d like it to be 75% or more,” Fauci said, but he acknowledged that may not be realistic.
