The phrase
"flu strains" refers to different types or variations of the flu virus.
Full definition

flu strains in the vaccine.

human flu strains and it will pass.
The animals can serve as mixing vessels where human and bird viruses swap genes, creating
new flu strains.
That includes tracking the myriad
flu strains circulating globally each year in animals and using the data to help develop candidate vaccine viruses.
One key problem from the outset was deciding which antibody to make, because there are many
different flu strains; a one - size - fits - all solution would be ideal.
Following these recommendations can help protect
from flu strains most likely to infect horses today.
Further, adding another B strain didn't compromise the vaccine's ability to cause the body to mount an immune response to the
other flu strains.
Health officials hope getting the word out about the severity of this year's
deadly flu strain can ultimately contain it.
However, researchers are working to develop universal vaccines that could protect against
multiple flu strains without needing to be updated.
And even if they were more dangerous than
common flu strains, it would not make any difference because manufacturers kill the virus as part of the vaccine production process, notes the group.
Identifying
novel flu strains in animals is one thing; determining whether they pose a human danger is another.
All of the vaccinated mice survived, while most of the other mice died, depending on which
flu strain caused their infection.
Dogs have no natural immunity to the virus, which is related to an
equine flu strain.
Unfortunately, without closer monitoring of the animal sources of
novel flu strains, human surveillance will have to remain the first line of defense.
However, they said the development of the vaccine was timely, amid concerns the H5N1
bird flu strain circulating in south east Asia could mutate into a pandemic strain which would put millions of lives at risk.
In the first two months of 2006, the spread of
avian flu strain H5N1 in Africa and Europe fanned fears that it might also spread among humans.
Finally, the study finds that genetic changes associated with adaptation to a new host seen in other flu viruses that have breached the species barrier — such as the avian
H5N1 flu strain — are not seen in the novel H1N1, suggesting that unknown changes in the new virus account for its ability to replicate and transmit in humans.
The authors confirm that the new strain is comprised of segments from
swine flu strains known to circulate in Europe, Asia and North America, but that this combination has not previously been seen and appears to have been evolving independently from its parent strains for some time.
The vaccines targeted an influenza A H1N1 seasonal
flu strain as well as A (H7N9), a virus considered to have the potential to trigger a human pandemic.
By using a few drops of blood from infected people, they could isolate antibodies to rapidly diagnose a newly
emerging flu strain such as H1N1.
During this time, a little over a quarter of all these people developed antibodies to the
H1N1 flu strain in circulation, indicating that they had become infected with the virus.
Columbia University microbiologist Vincent Racaniello, who helped develop the first artificial virus in the 1980s, cites the stir created four years ago when nearly 5,000 labs seeking accreditation were mistakenly shipped vials of the 1957
pandemic flu strain as part of their test kits.
Of the 15 distinct types of
flu strains known to occur in birds, H5N1 is «right at the top of the list for most - wanted strains,» says Richard Webby, a virologist at St. Jude Children's Research Hospital in Memphis.
So Palese's team exposed hundreds of guinea pigs to a human
flu strain at different temperatures and humidities, in cages that allowed only air to pass from sick animals to well ones.
The United States's move came amid long - running concerns about GOF studies involving highly pathogenic avian
flu strains such as H5N1.
In mice, message - receiving dendritic spines (bumps in lower panels) were sparse after infections
with flu strains H3N2 and H7N7.
A new vaccine could give protection for up to 88 % of known
flu strains worldwide in a single shot, spelling the end of the winter flu season.
All work on
mutant flu strains has been temporarily halted since January 20, 2012, when Fouchier, Kawaoka and 37 others called for a 60 - day pause to allow time for an open debate on the risks and benefits of such research.
Outbreaks of other
virulent flu strains in poultry have occurred in the United States, including one in Texas in 2004, but they were quickly eradicated and did not infect people.
When flu strains become too lethal among migratory birds, the birds die out before they can spread the infection to a new area.
The key to collecting these antibodies has been to remove B cells that bear them from survivors of, say, a
particular flu strain — or alternatively, someone who has been vaccinated against the flu (because the flu vaccine contains a weakened version of the virus).
Surveillance experts from the WHO, the US Centres for Disease Control and Prevention (CDC) in Atlanta and other agencies already monitor new
flu strains around the world, particularly in the East.
The biggest ever analysis of
flu strains shows the world's annual epidemic comes from the constant reservoir of bugs that follow the rainy season around East Asia
Ferrets are the only animal in the world that get the
same flu strains as people do.
The
contagious flu strain, known as H3N2, has killed at least 8 dogs and sickened more than 1,700 in the Chicago area, according to NBC News.
John Treanor, professor of medicine at the University of Rochester, and researchers at Connecticut - based Protein Sciences instead infected caterpillar cells with an insect virus — a baculovirus engineered to produce flu virus protein from three
ordinary flu strains.
It is a hybrid of human, bird and swine flu viruses, and by 1999 it is the
dominant flu strain in US pigs.
Efforts to develop a universal flu vaccine may have stalled, but the research has revealed an antibody that protects against several lethal flu strains
As a comparison, the researchers also exposed ferrets to an
airborne flu strain that caused a pandemic in 2009.
To create the weakened
flu strain contained in FluMist, the brand name of the nasal spray vaccine, nine mutations in the flu virus were made.
