The United States plans to have about 40 million doses of Covid-19 vaccine available to distribute by the end of the year, Health and Human Services Secretary Alex Azar said during a briefing on Wednesday.
The companies Pfizer and Moderna this week both announced that their vaccine candidates were about 95% effective in Phase 3 trials. Pfizer on Wednesday said final Phase 3 data confirmed the efficacy and it’s planning to apply for emergency use authorization from the US Food and Drug Administration on Friday.
The FDA must authorize any vaccine, but doses have already been manufactured in the hope that one or more would get authorization.
"By the end of December, we expect to have about 40 million doses of these two vaccines available for distribution pending FDA authorization — enough to vaccinate about 20 million of our most vulnerable Americans," Azar said. "And production of course would continue to ramp up after that."
