The German company BioNTech and Pfizer made a deal with the United States government to make 100 million doses of mRNA vaccine by December 2020. The vaccine completed phase I trials and started its next trial on July 27, 2020. Instead of being a phase II trial or a phase III trial, Pfizer's team is trying to do both phases at once. If the companies can make the vaccine on time, the U.S. government will give them almost US$2 billion. The vaccine is called BNT162b2. BioNTech paid its employees overtime to do extra work. They called this "Project Lightspeed" because they wanted to develop the vaccine quickly.
