Controversial experiments on bird flu could resume within weeks because leading influenza researchers around the world have finally called a halt to an unusual moratorium that has lasted more than a year.
The voluntary pause in the research started back in January 2012. Scientists had genetically altered the bird flu virus H5N1, changing it in ways that allowed it to spread through the coughs and sneezes of ferrets — the lab stand-in for people.
As the flu season grinds on from news cycle to news cycle, there's some flu news of a different sort. Federal regulators have approved a next-generation type of flu vaccine for the second time in two months.
The two new vaccines are the first fruits of a big government push to hasten and simplify the laborious production of flu vaccines.
Federal health officials say this year's flu season shaping up to be especially severe for the elderly.
According to the latest update from the federal Centers for Disease Control and Prevention, the number of people age 65 and older who are getting the flu jumped sharply in the last week or so. They are being hospitalized at a rate of about 82 per 100,000 cases. That's the rate that is seen during severe seasons, officials said.
