From Reuters:
“U.S. FDA
authorizes Pfizer COVID-19 vaccine for emergency use”
- The U.S. Food
and Drug Administration said it authorized the use of Pfizer Inc’s COVID-19
vaccine on Friday, with the first inoculations expected within days, marking a
turning point in the United States where the pandemic has killed more than 295,000
people. The FDA granted an emergency use authorization for the vaccine,
developed with German partner BioNTech, which was shown to be 95% effective in
preventing the disease in a late-stage trial. It said the vaccine can be given
to people aged 16 and older. Healthcare workers and elderly people in long-term
care facilities are expected to be the main recipients of a first round of 2.9
million doses.
Cases are
surging in the United States, with thousands of death per day, while hospital
intensive care units across the country are nearing capacity, threatening to
overwhelm healthcare systems. The timing gives the authorization “huge
importance”, BioNTech Chief Executive Ugur Sahin said in an interview. U.S.
health authorities, shipping services and hospitals stood ready to begin a
nationwide inoculation campaign. State public health systems have been planning
to begin shots as early as Monday.
Delivery
companies United Parcel Service and FedEx Corp plan to ship millions of the
Pfizer doses across the country, giving top priority to the vaccines on their
airplanes and trucks. Millions of Americans could begin getting vaccinated this
month, especially if a second vaccine from Moderna Inc is quickly approved. “It
is one step in a sequence of steps that will bring this pandemic to an end,”
said Amesh Adalja, a senior scholar at the Johns Hopkins Center for Health
Security. He added: “A lot of people will be infected, a lot will be
hospitalized and a lot will die before the vaccine is able to have a meaningful
impact on spread.”
The
Pfizer/BioNTech vaccine was first approved in Britain earlier this month, and
UK residents began receiving the shots on Tuesday. Canada also authorized the
vaccine and expects to start inoculations next week. Mexico and Bahrain have
also approved the Pfizer vaccine. U.S. President Donald Trump, in a video
posted on Twitter, trumpeted the achievement and blamed China for the pandemic.
Critics have said his focus on China was aimed at deflecting attention from his
missteps in combating the pandemic. “The United States is the first nation in
the world to produce a verifiably safe and effective vaccine. Today’s
achievement is a reminder of America’s unlimited potential,” Trump said.
COMPLEX
CHALLENGES Others with vaccines in advanced development include Moderna,
which could win emergency U.S. authorization as soon as next week, AstraZeneca
Plc with Oxford University, and Johnson & Johnson. BioNTech began
developing the vaccine in January, using a technology called synthetic
messenger RNA (mRNA) that had yet to produce an approved product. The
technology uses a chemical messenger to instruct cells to make proteins that
mimic part of the new coronavirus, which the immune system learns to recognize
as an invader. BioNTech struck a development deal with Pfizer in March. The
vaccine comes with complex distribution challenges as it must be shipped and
stored at -70 Celsius (-94 F), requiring specialized ultra-cold freezers or
supplies of dry ice. Moderna’s vaccine employs the same technology but
does not need to be stored at sub-Arctic temperatures. Pfizer has
developed a special shipping container that will be filled with dry ice to keep
the vaccine from spoiling. Many states are concerned about whether there is
enough dry ice for shipments to rural areas that lack the specialized freezers,
but Pfizer believes there should be sufficient supply. U.S. health
officials have said they will have enough to supply all of the 330 million U.S.
residents who wish to be vaccinated by the middle of 2021.
‘SOME DEGREE
OF NORMALITY’ The government has
ordered 100 million doses of the Pfizer vaccine - enough to inoculate 50
million people - through its Operation Warp Speed virus development program and
could negotiate for more. The status of those talks are unclear. Pfizer board
member and former FDA commissioner Scott Gottlieb said in an interview with
CNBC earlier this week that the company had offered to sell the United States
more doses as recently as last month but had been turned down. The United States
has agreed to buy 200 million doses of Moderna’s two-dose vaccine. The
government also has supply deals with J&J and AstraZeneca, but
authorization of those vaccines are not imminent. Top U.S. infectious diseases
expert Dr. Anthony Fauci said if distribution goes well and enough Americans
agree to get vaccinated, relief for a pandemic weary nation may be on the
horizon. “As we get to the end of 2021, we could approach very much some degree
of normality that is close to where we were before.”
^ While this is
a great step in the right direction there won’t be enough vaccines for every
American until at least the Spring of 2021. Also we don’t know if Covid-19 with
change (mutate) every year like the flu does so we don’t know how effective any
of these vaccines will be next Fall. ^
