(CNN) — News that Pfizer's coronavirus vaccine strongly protects people against infection is good news for other vaccines being developed against the pandemic, said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.
News that Pfzer's Covid-19 vaccine provides more than 90% protection is good news for other coronavirus vaccines in the works.
Pfizer said its candidate vaccine was more than 90% effective in preventing infection in volunteers. It uses a never-before-approved technology called messenger RNA, or mRNA, to produce an immune response in people who are vaccinated.
“This shows that the mRNA platform actually does work. And there's another vaccine candidate, Moderna, that's using the same platform,” Fauci told CNN in a telephone interview.
The US federal government has invested $1.95 billion in Pfizer and BioNTech's vaccine but is not directly working to help its development.
The mRNA vaccine approach uses genetic material called mRNA to trick cells into producing bits of protein that look like pieces of the virus. The immune system learns to recognize and attack those bits and, in theory, would react fast to any actual infection. — Maggie Fox, CNN/@CNN
