Researchers are working to treat pandemic flu by recruiting a patient's own immune cells.

Viruses multiply incredibly quickly once they've infected their victim--so fast that antiviral medications such as Tamiflu are only effective if given during the first few days of an infection. After that, the viral load is just too high for a single drug to fight off. But researchers are working on a treatment for the H1N1 virus (or swine flu) that uses a different approach. Rather than disabling the virus with a drug, they're creating a vaccine that can activate and steer a patient's own immune cells to attack the invader.

GENEVA (Reuters) - The new H1N1 flu virus could still mutate into a more virulent form and spark an influenza pandemic that could be expected to circle the globe up to three times, the World Health Organization said on Tuesday.

The impact of any pandemic would vary, as a virus that causes only mild illness in countries with strong health systems can become "devastating" in those with weak health systems, shortages of drugs and poorly equipped hospitals, it said.
