President Donald Trump, back in the White House days after being diagnosed with COVID-19, said vaccines in the fight against the coronavirus pandemic would come “momentarily. “
Doctors and scientists have refuted this claim.
Trump, speaking in a video posted on Twitter after leaving Walter Reed National Military Medical Center on Monday, said he felt “better than 20 years ago” after praising the drugs and gadgets involved in his treatment. people deserve not to be afraid of COVID-19, and said, “Maybe I’m immune, I don’t know” in Monday night’s video.
In the video, Trump said, “Vaccines are coming momentarily. “
To have a COVID-19 vaccine in the United States, sufficient knowledge of Phase 3 clinical trials would first need to be collected to demonstrate to the Food and Drug Administration that it is safe, effective, and immune to the virus.
Data, knowledge and more knowledge: It will make a vaccine opposed to coronavirus safe, according to the USA TODAY vaccine panel
At this stage, the FDA will ask its external review committee, the Advisory Committee on Vaccines and Related Biological Products, if it agrees. Only then can the firm apply for an emergency use authorization or continue with the full licensing procedure to license the vaccine.
Dr. Paul Pottinger, professor of infectious diseases at the University of Washington School of Medicine, said he hoped there would soon be smart news about ongoing trials, but understands that a “solid supply” of a vaccine can be obtained for public use will not be available for “many, many months. “
“Remember there is a lag between when we know something is safe and effective and when it can be generally implemented,” he said. “But there will not be a safe, sometimes effective vaccine that can be implemented at any time. ” , I am very confident. “
On September 16, CDC Director Robert Redfield said that even once a vaccine was approved, only limited amounts would be available in the first place. The American public, he predicted, could not get it and “go back to general life” until next summer or fall. Trump later said Redfield had misrepresented.

Four candidate vaccines are currently being tested in phase 3 trials, each of which receives at least another 30,000 people, one of whom will get the active vaccine and the other a placebo.
Dr. Stephen Hahn, head of the FDA, has continually stated that he will not approve a vaccine until it is shown and effective. He also said there may be an intermediate valuation criterion, in addition to completing a 30,000-person trial, which may simply meet its criteria for an emergency use authorization.
Advance approval may be issued in the event of a federal fitness emergency.
Scientists ”absolutely brazen” outraged by interference by White House appointees in information on coronavirus
The fastest vaccine ever developed took 4 years. Work on a COVID-19 vaccine has been done at a much faster pace, thanks to technological advances, studies on even smaller coronavirus outbreaks, concerted effort through businesses, and federal support.
Public fitness officials, who testified before Congress on September 30, said the policy influenced the progression of a COVID-19 vaccine.
Independent researchers and they are largely following vaccine development, said Dr. Mark McClellan, director of duke-Margolis Health Policy Center at Duke University and former FDA commission.
Trump: CDC Director Robert Redfield is ‘confused’ about vaccine and coronavirus effectiveness
“It’s not a simple procedure to interrupt just because it says something about it,” he said at the time. “However, it undermines trust. “
Cdc, in a plan-making paper detailing how local states and public fitness systems plan and prepare for the launch of one or more COVID-19 vaccines, said that “limited doses” of a vaccine may be obtained in early November. .
In the document added, planners assume that until January 2021, “much more COVID-19 vaccine could be available for distribution”.
It will take a while: when will young people receive the COVID-19 vaccine?
Dr. Otto Yang of the University of California, Los Angeles, sees approval until the new year.
“I don’t think we can have a safety knowledge smart enough until at least winter (three to 4 months of verification knowledge). Shorter than that is very little time, regardless of the outcome,” said Yang, professor of medicine and associate leader of infectious diseases at UCLA’s David Geffen School of Medicine.
