H1N1 Deaths in NC getting attention from federal health officials

Recent deaths caused by the H1N1 virus in North Carolina are getting some attention by federal health officials.
Last week, officials revealed three patients at Duke, with unhealthy immune systems, died of a strain of H1N1 that was resistant to the drug Tamiflu.
Health and Human Services Secretary, Kathleen Sebelius, called their deaths an unusual occurrence.
Sebelius says now, they’re keeping a close eye on certain vaccines, and how well they fight off the H1N1 virus.
Since H1N1 has been discovered, scientists have worried it might mutate into something more dangerous, but so far they say that hasn’t happened.
