Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases of the National Institutes of Health, told ABC’s “This Week with George Stephanopolous” on Sunday that this year’s flu vaccine is only “30 something” percent effective against the current influenza virus.
“And one of the things that is clearly different about this year is — is the flu shots are not as effective, maybe just 60 percent effective…” host Martha Raddatz said, but Fauci corrected her, saying, “No, less – 30 something.”
“Thirty something,” Raddatz said.
“And 67 percent uneffective,” said Fauci.
“Uneffective, then even worse than I thought,” Raddatz said.
According to NIAID, flu viruses change from one season to the next and can even change within one flu season. But even if a vaccine is not a good match, antibodies made in response to vaccination with one flu virus can sometimes offer protection for different related viruses.
