Covid-19: Pfizer seeks emergency use of vaccine in US

Covid-19: Pfizer seeks emergency use of vaccine in US”

It will be the job of the US Food and Drug Administration (FDA) to decide if the vaccine is safe to roll out.

"We'll drill down on these data", said FDA adviser Dr. Paul Offit of the Children's Hospital of Philadelphia. The platform is fast and flexible for developing vaccines, since it only requires knowing the genetic sequence of the virus the vaccine will target, rather than growing and manipulating the virus in question.

The CureVac vaccine is expected to begin deliveries in late March.

The trial involved 41,000 people worldwide.

The official added that the European Union will pay 10 euros a pop for 225 million doses of CureVac's vaccine candidate, down from 12 euros per shot price tag which the company initially suggested.

So when could we expect vaccinations?

"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.

How was this vaccine developed so quickly?

"Filing in the U.S. represents a critical milestone in our journey to deliver a COVID-19 vaccine to the world and we now have a more complete picture of both the efficacy and safety profile of our vaccine, giving us confidence in its potential", Pfizer CEO Albert Bourla said. Stephen Evans, professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine, said both the FDA and the European Medicines Agency (EMA) would "conduct a very careful evaluation".

The Pfizer-BioNTech vaccine - and Moderna's candidate - are made with brand-new technology. That result held true across age, gender, racial and ethnic categories. The most common adverse event rated as "severe" in the trial was fatigue, in 3.7 percent of participants after the second dose. It will then stimulate the immune system to create antibodies against the virus.

The US this week passed 250,000 deaths in the coronavirus outbreak, by far the largest number in the world. "With today's news, we are a significant step closer to providing people around the world with a much-needed breakthrough to help bring an end to this global health crisis".

Japan was also on "maximum alert" after logging a record 2,000 daily infections with almost 500 in the capital Tokyo alone, though no immediate restrictions were planned.

California will also impose a 10 p.m.to 5 a.m. curfew from Saturday - a measure that mirrors one that Istanbul will start imposing for its 15 million residents on weekends starting Friday night.

U.S. states and cities are imposing a raft of new restrictions, including home confinement, the closure of indoor dining and a limit on gatherings as cases soar.

The U.S. has also purchased 100 million doses of Moderna vaccine in advance. It too uses the mRNA approach.

"Controversy over the safety of the vaccine is natural as the development stage of the vaccine was so compressed", he said. The deal between Brussels and CureVac reportedly includes a 225 million dose mandatory purchase, with the option to buy 180 million more doses, for a total of 405 million, and 4.05 billion euros.

The COVID-19 vaccine will contain mRNA encased in tiny particles that are transported into our cells. The only way of knowing whether a vaccine works is by providing a "control", which is a demonstration of what would happen in its absence.

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