WASHINGTON - US healthcare workers and others recommended for the nation’s first Covid-19 inoculations could start getting shots within a day or two of regulatory consent next month, a top official of the government’s vaccine development effort said on Sunday (Nov 22).
Some 70 per cent of the US population of 330 million would need to be inoculated to achieve "herd" immunity from the virus, a goal the country could achieve by May, according to Dr Moncef Slaoui, chief scientific adviser for "Operation Warp Speed."
Dr Slaoui said the US Food and Drug Administration (FDA) would likely grant approval in mid-December for distribution of the vaccine produced by Pfizer Inc and German partner BioNTech, launching the largest inoculation campaign in US history.
The FDA’s outside advisers are slated to meet on Dec 10 to review Pfizer’s emergency-use application for its vaccine, which the company said was found to be 95 per cent effective against infection from the highly contagious respiratory virus.
A second pharmaceutical company, Moderna Inc, is expected to seek separate approval later in December for its Covid-19 vaccine.
Appearing on several network news shows on Sunday morning, Dr Slaoui sketched out a timeline for getting the initial doses of the Pfizer vaccine from FDA authorisation into the arms of those who will be first in line to receive it.
"Within 24 hours from the approval, the vaccine will be moving and located in the areas where each state will have told us where they want the vaccine doses," Dr Slaoui told NBC's Meet The Press.
"So I would expect, maybe on day two after approval on the 11th or 12th of December, hopefully the first people will be immunised across the United States," he said on CNN’s "State of the Union" programme.
Once emergency-use approval is granted, Dr Slaoui said, the US Centres for Disease Control and Prevention (CDC) and an advisory panel on immunisation practices will recommend who should receive the vaccine first.
Dr Slaoui said they are likely to include doctors, nurses and "frontline" emergency medical personnel, as well as individuals considered to be at the highest risk of severe illness and death from the virus, such as the elderly.
Public health authorities in each state will be responsible for administering the vaccine roll-out, with the first doses distributed to the states proportionate to their populations, he said.
President-elect Joe Biden and his advisers have voiced concern that President Donald Trump’s continued refusal to share vaccine data and distribution plans with Biden’s transition team could cause delays after the next administration takes office on Jan 20.
Dr Slaoui said he hoped for a smooth hand-off and did not expect the vaccination effort to be derailed.
Details on the timeline emerged as coronavirus infections continued to rage out of control across the country, further straining hospitals besieged with growing numbers of Covid-19 patients.
The crisis has prompted state and local government leaders nationwide to re-impose restrictions on social and economic life in hopes of breaking the transmission cycle.
On Sunday, Los Angeles County health officials announced that outdoor service at restaurants, bars and wineries would be banned for at least the next three weeks as the daily number of new coronavirus cases surpassed a five-day average of 4,000.
The new measure, restricting eateries in and around the nation’s second-largest city to takeout and deliveries only for the first time since late May, goes into effect on Wednesday (Nov 25).
Public health experts worried that the surge will only worsen, as millions of Americans prepared to travel and congregate in family groups for Thanksgiving celebrations, despite warnings that they stay home to avoid spreading the disease.
Many people were scrambling to get tested before Thursday’s (Nov 26) holiday, leading to long lines at screening sites in New York City and elsewhere.
Most pharmacies offering Covid-19 tests in suburban Chicago were fully booked.
"I believe Covid rates will increase just as I believe most New Yorkers will put on weight," New York Governor Andrew Cuomo lamented at a Sunday press conference.
Mr Cuomo also said the city was investigating reports of an ultra-Orthodox Jewish wedding that drew some 7,000 people to a reception in Brooklyn, video footage of which showed throngs of maskless guests celebrating shoulder to shoulder.
The United States surpassed 12 million Covid-19 cases on Saturday (Nov 21), as the nation’s death toll climbed to more than 255,000 since the pandemic began.
Coronavirus hospitalisations have increased nearly 50 per cent over the past two weeks.
Reuters data showed the pace of new infections quickening, with nearly 1 million more cases documented over the past six days, compared with the eight days it took to get from 10 million to 11 million cases.
The epicentre of the US pandemic has also shifted in recent weeks, with the Midwest and Rockies leading the nation in terms of rapidly escalating infections.
"It’s really spread across the country," Dr Tom Inglesby, director of the Centre for Health Security at Johns Hopkins University, said on Fox News Sunday.
"It’s not just in big cities, but it’s in rural locations, small towns."
While the prospect of effective vaccines has brought new hope to a country whose social and economic life has been upended by the virus, public distrust of inoculations runs high.
In a recent Gallup poll, just 58 per cent of Americans said they planned to get a Covid-19 vaccine, up from 50 per cent in September.
Incoming White House Chief of Staff Ron Klain said vaccine distribution also brings formidable logistical challenges.
"Vaccines don’t save lives, vaccinations safe lives," he told ABC on Sunday. "The much bigger step is actually getting those vaccinations to the American people. That’s hard."
