United Kingdom Clears Pfizer's COVID-19 Vaccine
The United Kingdom has cleared Pfizer's COVID-19 vaccine and will begin providing the vaccines to people within days.
The United Kingdom is the first country in the world to authorize the vaccine.
Getting everyone vaccinated will take some time. This will be the biggest vaccine program in the country's history.
In May 2020, Pfizer began testing four different COVID-19 vaccine variations to help end the COVID-19 pandemic and planned to expand human trials to thousands of test patients by September 2020.
The pharma company injected doses of the potential vaccine BNT162b2, which was developed by the German biotechnology company BioNTech based in Mainz, Germany, into the first human participants in the U.S. in early May.
Based on the results, Pfizer said they "will be able to deliver millions of doses in the October time frame" and expects to produce hundreds of millions of doses in 2021.
In July 2020, Pfizer and BioNTech announced that two of the partners' four mRNA vaccine candidates had won fast track designation from the FDA.
The company began Phase 3 testing in the last week of July 2020 on 30,000 people and was slated to be paid $1.95 billion for 100 million doses of the vaccine by the United States government.
The U.S. deal priced two doses at $39 and the company stated that it would not lower the rates for other countries until the outbreak is no longer a pandemic.
In October 2020, it was reported that Pfizer would start testing the COVID-19 vaccine developed by BioNTech on a broader range of subjects including children as young as 12. This would be the first coronavirus vaccine trial to include children in the United States.
On November 9, 2020, Pfizer announced that the vaccine appeared to be over 90% effective. On November 20, 2020, Pfizer applied for Emergency use authorization from the Food and Drug Administration for the vaccine.
