WASHINGTON, D.C.--A new type of flu vaccine, delivered in a nasal spray, has produced an immune response in children in a small field trial.
Researchers say they are closer to developing a vaccine to give life-long protection against any type of flu, after promising trials in animals.
Instead, the researchers started with a type of duck flu and spliced in genes from the highly contagious 1918 Spanish flu.
But because of swine flu fears and the fact that Mr. Erling has cystic fibrosis, making him especially vulnerable to any type of flu, they have decided to postpone their event and are now considering either taking the wedding to Jamaica on another date, or waiting it out.
VaxInnate is also developing another vaccine, even more radical, that might work against any type of flu without yearly revisions for new strains.
The experiments involve a type of bird flu virus known as H5N1.
But the virus, a type of bird flu, does not often infect people, and when it does, they almost never transmit it to one another.
The experiments involve a type of bird flu virus known as H5N1, which rarely infects people but is highly deadly when it does.
Researchers have found that a small change in a gene called PB2 helps make a type of bird flu contagious in ferrets by enabling the virus to copy itself at the temperatures found in a mammal's nose, which is 4 degrees Celsius cooler than a bird's intestines.
A type of bird flu known as H5N1 is deadly and has killed about half the people who have been infected.
We agree with Doshi (1 ) that in our study reported in "Public Response to Community Mitigation Measures for Pandemic Influenza" (2 ), we purposely asked respondents to imagine a "severe outbreak" of "a new type of flu," and that possible scenario was vastly different from ordinary flu seasons.
