Deliberate flu?

Volunteers sneeze for science

BETHESDA, Md. (AP) — Forget being sneezed on: Government scientists are deliberately giving dozens of volunteers the flu by squirting the live virus straight up their noses.

It may sound bizarre, but the rare type of research is a step in the quest for better flu vaccines. It turns out that how the body fends off influenza remains something of a mystery.

"Vaccines are working, but we could do better," said Dr. Matthew Memoli of the National Institutes of Health, who is leading the study that aims to infect up to 100 adults over the next year.

Wait a minute: Flu is sweeping the country, so why not just study the already sick? That wouldn't let scientists measure how the immune system reacts through each step of infection, starting with that first exposure to the virus.

It's not an experiment to be taken lightly. After all, the flu kills thousands of Americans a year. For safety, Memoli chose a dose that produces mild to moderate symptoms — and accepts only volunteers who are healthy and no older than 50.

And to avoid spreading the germs, participants must spend at least nine days quarantined inside a special isolation ward at the NIH hospital, their health closely monitored. They're not released until nasal tests prove they're no longer contagious.

The incentive: About $3,000 to compensate for their time.

"I received a very scolding email from my mother" about signing up, Daniel Bennett, 26, said with a grin.

"Their standards are so high, I don't believe I'm in danger," added Bennett, a restaurant worker from College Park, Md. "I don't get sick that often."

A masked and gloved Memoli had Bennett lie flat for about a minute.

"It will taste salty. Some will drip down the back of your throat," Memoli said, before squeezing a syringe filled with millions of microscopic virus particles, floating in salt water, into each nostril.
