Although we’ll be getting a further release of information tomorrow from the NIH, Dr. Anthony Fauci has signaled that US clinical trial data on the novel H1N1 vaccine matches that which was released earler today by Australia’s CSL Ltd., which indicates that a single 15 microgram unadjuvanted shot produces good immune responses in adults over and under the age of 50.
Piling on the good news is that antibody titers reach protective levels in just 8 to 10 days after immunization, which is considerably sooner than had been expected.
All of this significantly loosens up tight vaccine supplies and lessens some of the logistics involved in getting the vaccine out into the arms of the population.
Studies: 1 dose of swine flu vaccine works

WASHINGTON — Good news in the world's flu fight: One dose of the new swine flu vaccine looks strong enough to protect adults — and can spark protection within 10 days of the shot, Australian and U.S. researchers said Thursday.
Australian shot maker CSL Ltd. published results of a study that found between 75 percent and 96 percent of vaccinated people should be protected with one dose — remarkable considering scientists thought it would take two doses.
U.S. data to be released Friday confirm those findings, and show the protection starts rapidly, Dr. Anthony Fauci of the National Institutes of Health told The Associated Press.
"This is quite good news," Fauci said.
