The United States under President Joe Biden intends to join the COVAX vaccine facility that aims to deliver coronavirus vaccines to poor countries, his chief medical adviser, Anthony Fauci, told the World Health Organization (WHO).

Pfizer Chief Executive Officer Albert Bourla said his company supports Joe Biden’s $1.9 trillion coronavirus-focused plan that is intended to boost vaccination efforts and address the pandemic.

Scientists at the National Institutes of Health and Moderna Inc. may take about two months to determine whether doses of the company’s Covid-19 vaccine can be halved to double the supply of the shots in the U.S., according to the agency.

Leading U.S. infectious disease specialist Dr. Anthony Fauci said he foresees America achieving enough collective Covid-19 immunity through vaccinations to regain “some semblance of normality” by autumn 2021, despite early setbacks in the vaccine rollout.

The United States recorded more than 15,000 deaths from Covid-19 and over 1.2 million new cases for the week ended Dec. 27, though those numbers may be artificially low due to reporting gaps over the Christmas holiday.

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.

Daily U.S. deaths from Covid-19 surpassed 3,000 for the third time in a week as the country expanded its vaccination program and Congress progressed toward approving financial relief for pandemic-stricken America.

Pfizer, COVID vaccine

The United States authorized the use of Pfizer Inc’s Covid-19 vaccine on Dec. 11, with the first inoculations expected within days, marking a turning point in a country where the pandemic has killed more than 295,000 people.

President-elect Joe Biden made his selections for two key public health positions, sources said, as he prepares to take office in January while the coronavirus pandemic rages to new levels across the United States.

California shattered records for coronavirus cases on Dec. 6 as U.S. states scrambled to impose lockdowns to stem spikes in infections and the White House’s task force coordinator decried a lack of national leadership on curbing the disease.
