  • In an update on coronavirus vaccine candidates, Dr. Anthony Fauci noted that a drug that's 70% to 75% effective at preventing COVID-19 will not lead to herd immunity in the US if only two-thirds of the population seek immunization.
  • Fauci acknowledged the power of the anti-vaccine movement and said public health campaigns to educate people on the safety of vaccines will be needed.
  • The first COVID-19 vaccines could be ready for emergency use later this year, once they clear Phase 3 of clinical trials successfully.

Several vaccine candidates for the novel coronavirus have shown promising results in the first stages of human trials, and some of them may be approved for emergency use as soon as this fall or winter if all goes well. That's what we keep hearing from officials involved in these endeavors, and that's a lot sooner than anyone would have expected. But it will take a lot longer for these vaccines to be widely available and meet demand.

Pharmaceutical companies aimed to mass-produce 15 billion doses in total to cover the world's population twice over. That's because the vaccines might need two shots to deliver results. In other words, it could be years until the entire world's population gets the vaccine, no matter how soon emergency use starts.

If deployed in large numbers, vaccines can prevent COVID-19 infections and reduce the spread of the disease significantly. Immunity gained via inoculation or by surviving an initial encounter with the virus would deliver the herd immunity all of the countries fighting COVID-19 want.
