Pharmaceutical giant Pfizer continues to pump out good news with respect to its groundbreaking COVID-19 vaccine.
Shortly after announcing their coronavirus vaccine was 90% effective in late-stage trials, Pfizer is beginning pilot distribution programs in four U.S states -- Rhode Island, Texas, New Mexico and Tennessee.
Pfizer also adjusted its efficacy rate, now declaring its vaccine is over 95% effective.
The states selected for the pilot distribution program were chosen due to “their differences in overall size, diversity of populations, and immunization infrastructure, as well as the states' need to reach individuals in varied urban and rural settings,” the company said.
In July, Pfizer and BioNTech announced the execution of an agreement with the U.S. Department of Health and Human Services and the Department of Defense to meet the U.S. government’s 'Operation Warp Speed' program goal to begin delivering 300 million doses of a vaccine for COVID-19 in 2021.
Under the agreement, the U.S. government will first receive 100 million doses of the Pfizer-BioNTech COVID-19 vaccine after Pfizer successfully manufactures and obtains approval or emergency use authorization from the U.S. Food and Drug Administration (FDA).
The U.S. government will pay $1.95 billion for those first 100 million doses, with the option to acquire up to an additional 500 million doses.
On Wednesday, Pfizer announced that, due to the consistent and promising data from its vaccine trials, it would be seeking FDA approval "within days."
