The researchers also tested the experimental vaccine's ability to protect ferrets from infection with a 2007 strain of H1N1 influenza
virus-a strain it had not been specifically designed to prevent.

A total sample size of 66 patients (33 in patients with H1N1 and 33 patients without H1N1) would be needed to detect a difference of 9 [micro]g/l in PCT between those who were positive and negative to H1N1 influenza
(alpha level 5%; power 80%) (26).
Numerous other aspects of the health care response included the availability and timeliness of confirmatory testing for 2009 H1N1 influenza
by state and other public health laboratories, as well as elements of individual laboratory preparedness and response.
If the behavior of the seasonal form of H1N1 influenza
virus is any indication, scientists say that chances are good that most strains of the pandemic H1N1 flu virus will become resistant to Tamiflu, the main drug stockpiled for use against it.
Two people with compromised immune systems who became ill with 2009 H1N1 influenza
