The United States could get Covid-19 under control by early 2022, with potential wider vaccine approvals coming in the weeks ahead, Dr. Anthony Fauci said one day after Pfizer won wider FDA approval for the company’s novel coronavirus shot on Aug. 23.

The United States will likely fail to meet President Joe Biden’s goal to deliver at least one Covid-19 vaccine to 70 percent of adults by July 4, officials said on June 22 and warned the Delta variant first found in India poses the greatest threat to U.S. eradication efforts.

Dr. Anthony Fauci, the top U.S. infectious disease expert, said on March 14 he hopes former President Donald Trump will push his supporters to get the Covid-19 vaccine and emphasized that pandemic-related restrictions should not be lifted prematurely.

The head of the U.S. Centers for Disease Control and Prevention said on Feb. 14 it is “absolutely” too soon to lift mask mandates, citing daily Covid-19 case numbers that despite recent declines remain more than double the levels seen the summer of 2020.

As Operation Warp Speed – the Trump administration’s program to develop and distribute a Covid-19 vaccine – struggles to ramp up vaccinations, one of the approaches under consideration is cutting the doses of the Moderna vaccine.

U.S. Vice President Mike Pence received his Covid-19 vaccine live on television on Dec. 18, seeking to shore up public support for vaccinations after U.S. deaths from the coronavirus topped 3,000 for a third straight day.

U.S. infectious disease expert Anthony Fauci said he was reacting to gloating by a British television interviewer when he criticized the country’s quick approval of the first coronavirus vaccine.
