One shot of vaccine to prevent H1N1

One shot of the H1N1 influenza vaccine will be sufficient protection for adults, according to clinical trials conducted in Australia and published Thursday in The New England Journal of Medicine. This overturns previous scientific thought that adults would require two shots, and nearly doubles the amount of vaccine available.

 

Students at the University of Minnesota, which confirmed about 60 cases of influenza-like illness on campus Thursday, will have access to the vaccine when it becomes available in mid-October.

 

People under 9-years-old will still need two shots, because their immune system is less developed. This is common practice with the seasonal flu shot as well.
