Remarking on images of the Pfizer/BioNTech vaccine being shipped out, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said the coronavirus vaccine is "truly historic."
"Of all the vaccines that I have been involved in the development of, this stands out as the most stunning accomplishment. Truly an extraordinary team effort involving academia, government, and private sector," Fauci told CNN.
The team at NIAID helped develop Moderna’s Covid-19 vaccine. Vaccine advisers to the Food and Drug Administration will meet next week to discuss an emergency use authorization for Moderna’s vaccine.
The science: Both Moderna’s candidate and Pfizer/BioNTech's recently authorized vaccine have been shown to be about 95% effective in preventing symptomatic infections. Both vaccines rely on the same technology, using a synthetic version of mRNA or Messenger RNA, a strand of genetic code.
The Pfizer vaccine is the first vaccine in the world to be authorized using this technology. It is now authorized for emergency use in the United Kingdom, Canada, and the United States.
