What does emergency use for a COVID-19 vaccine mean?

Pfizer chief executive officer Albert Bourla confirmed the application had been made in a video posted on the company's website on Friday afternoon.

European Commission president Ursula von der Leyen said the EU could move quickly too - by the end of the year.

Half of the participants in Pfizer's trial received two doses of the study vaccine and half received two shots of saline.

Among the vaccine front-runners, the Pfizer-BioNTech project is the only one that didn't take funding from the White House-led Operation Warp Speed program to accelerate development, manufacturing and distribution of Covid-19 shots.

The more people who can experience milder symptoms and recover at home, the less burden on the health care system and the less exposure that health care workers will have to the virus, which all contributes to better control of the pandemic.

An emergency authorization for a vaccine is typically a lower standard than full approval. That's a milestone FDA set because historically, vaccine side effects don't crop up later than that. Despite repeated claims, we are still months away from the coronavirus vaccine, therefore, limited options are left for us to remain honest to our duties toward society and its people to save the nation from this deadly virus.

"If a vaccine is approved, it will, of course, be available across the United Kingdom from our NHS, free at the point of delivery, according to need not ability to pay".

However, the US FDA is yet to give a time frame on how long it would take to review the data on vaccine efficacy and safety, which are the two main criteria.

If there's an emergency green light, "that vaccine is still deemed investigational".

No mRNA vaccines have been approved before because it is relatively new technology. The agency must determine the product's "known and potential benefits outweigh its known and potential risks".

There will be a lot of unknowns.

That means that people who are vaccinated are not necessarily immune to getting infected; but they are more likely to experience fewer symptoms and not get as sick as those who aren't vaccinated.

Rittenhouse is charged with first-degree intentional homicide, which could land him in prison for life, if convicted. He told the newspaper that he was carrying the gun that night to protect himself.

Prof Van-Tam said: "What is now really important is that the vaccine is accessible to all communities irrespective of their ethnic background and that people come forwards when they are called and the uptake is very high".

That's why the 44,000-person study needs to keep running - something hard considering ethically, participants given dummy shots at some point must be offered a real vaccine, complicating the search for answers.

And at least for now, pregnant women won't qualify because they weren't studied.

Other vaccines are in late testing stages in China and Russian Federation.

In July, the Trump administration as part of Operation Warp Speed, had agreed to provide Pfizer with Dollars 1.95 billion to manufacture and distribute its COVID vaccine, and allowing the vaccine to be provided free for Americans.

"That will depend on the speed at which the vaccines can be manufactured". "And if supported by the data, the FDA is likely to issue an EUA for this vaccine".

Traditional virus vaccines use actual viruses that can take months or years to develop.

It uses an experimental approach, called mRNA, which involves injecting part of the virus's genetic code into the body to train the immune system. "We will prioritise groups who are at greatest risk".

"Pfizer's partner BioNTech has announced that tomorrow they intend to file for emergency use authorization at the FDA", health secretary Alex Azar told a press conference Thursday in Washington.

Pfizer's shares were up 1.3% and BioNTech shares up 9.3% in NY late on Friday afternoon, as the possibility of a vaccine soon raised hopes for the end of a pandemic that has claimed more than a quarter of a million lives in the United States and over 1.3 million worldwide.

"It's not like a pizza", he said.
