To prepare for a potential pandemic of avian influenza caused by H5N1, the Food and Drug Administration approved the first vaccine boosted so its doses can provide stronger immune responses against the flu virus.
The latest version is called H6N1, and represents the first time that this strain of bird flu has jumped from birds to people.
Researchers discovered it before it became a pandemic, but there’s no vaccine for it yet
The first estimates of the severity of the H7N9 influenza virus show that about one-third of people who were hospitalized with the infection died. And flu experts warn that the strain could reappear in the next flu season.
Researchers have more questions than answers about the latest bird flu circulating in China, including whether birds are the only reservoir for the virus.
Researchers who created a so-called superstrain of H5N1 bird flu say the virus may not be as lethal or as virulent as has been widely suggested.
A new study suggests H5N1 is more easily spread and far less deadly than scientists believed. What does that mean for work on potentially lethal man-made versions of the virus?
Since August, the CDC has logged 12 cases of human infection with H3N2, a new flu virus from pigs. Should we be worried?
In an unprecedented move, the U.S. government asked scientific journals not to publish the details of experiments on the deadly H5N1, for fear that the information could be used with malice. Is such censorship smart?
Back at the start of 2009, I thought I was sure where the next influenza pandemic would come from: Asia. I’d spent a few years in the region following the steady progression of the H5N1 avian flu virus as it spread from wild and …
Hong Kong residents experienced an unwelcome blast from the past on Nov. 18. A 59-year-old woman in the city contracted H5N1 avian influenza — the first confirmed case in Hong Kong since 2003.
The H1N1 flu pandemic last year came out of nowhere. Well, not exactly — H1N1 first emerged in human beings in Mexico. But that wasn’t where most influenza experts were looking. The focus had been on southeast Asia, where the H5N1 avian flu had been infecting — and killing — human beings for the past few years. Most flu pandemics …
