The US government is “cautiously optimistic” that one or two vaccines, likely from Pfizer Inc or Moderna Inc, will be available by the end of the year and can begin to be distributed to Americans, officials said during a news conference.
Azar said he expects all seniors, healthcare workers, and first responders will be able to receive a vaccine as soon as January, with the rest of the American public able to get a vaccine by April.
Companies participating in the US government’s effort to develop a vaccine for COVID-19, dubbed Operation Warp Speed, have begun developing manufacturing capabilities even before any vaccinations have been authorized by regulators.
In an open letter published last week, Pfizer said it is unlikely to have enough data to submit for a US regulatory authorization until late November, after the US presidential election.
The coronavirus outbreak has been worsening in recent weeks as cold weather pushes Americans indoors, raising the chance of contracting the virus. Some 38 US states and two territories have reported rising case counts.
More than 8 million Americans have been infected with the novel coronavirus and more than 200,000 have died.
