Pfizer on Tuesday released a pilot shipping plan for its experimental vaccine in Rhode Island, Texas, New Mexico, and Tennessee. The plan, Pfizer said, was to try to tackle distribution problems with regards to its ultra-cold storage necessities.
The organizations are reportedly charging $20 for every dose for its vaccine, considerably lower than Moderna.
Pfizer and BioNTech have secured agreements with several international locations across the globe. The European Union has requested the most, with 300 million doses confirmed as of Nov. 11, Japan has agreed to procure 120 million, and the U.S. has acquired 100 million.
