Writing this week (May 23, 2016) in the journal Nature Microbiology, a team of researchers led by University of Wisconsin - Madison School of Veterinary Medicine virologist Yoshihiro Kawaoka describes a novel strategy to predict the antigenic evolution of circulating influenza viruses and give science the ability to more precisely anticipate seasonal flu strains.

But WHO, following criticism from member countries that declaring phase 6 could cause undue alarm about a virus that appears no more dangerous than seasonal flu strains, has been reluctant to declare this a full - scale pandemic.

Seasonal flu strains such as H1N1 and H3N2 have shown little resistance to the drug in adults, but two small studies have shown resistance rates of up to 18 % in Japanese children (ScienceNOW, 26 August 2004).

This suggests that the pandemic virus will displace the two previous seasonal flu strains, as previous pandemics have done.

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.

Not exact matches

The current crop of seasonal flu vaccines, which contain H1N1, H3N2 and B flulike strains, are egg - based.

They were randomized to receive one of three vaccines: the quadrivalent flu vaccine that contained two A flu strains and both lineages of the B strains; the licensed trivalent intradermal vaccine for the 2012 - 2013 flu season; or an alternate trivalent intradermal vaccine that contained two A strains and the B strain that was not in the licensed seasonal flu vaccine.

The responses of those given the quadrivalent vaccine were the same as those of volunteers who received the vaccine with two strains of A and the strain of B that matched the B strain in the 2012 - 2013 seasonal flu trivalent vaccine.

So, researchers at CDC and collaborators used a lab technique called reverse genetics to make combinations of H3N2, a seasonal human flu strain, and the 1997 strain of H5N1.

Strains of H3N2 have been circulating in humans since the 1968 pandemic, but they have evolved to a less dangerous form that produces a nasty seasonal flu.

Using X-ray crystallography, performed at the European Synchrotron Radiation Facility (ESRF) in Grenoble, Cusack and colleagues were able to determine the atomic structure of the whole polymerase from two strains of influenza: influenza B, one of the strains that cause seasonal flu in humans, but which evolves slowly and therefore isn't considered a pandemic threat; and the strain of influenza A — the fast - evolving strain that affects humans, birds and other animals and can cause pandemics — that infects bats.

Researchers around the world, including at the University of Rochester Medical Center (URMC), are pursuing a «universal» flu vaccine, one that would protect against most or all seasonal and pandemic strains of the flu virus.

They found that seasonal flu escapes immunity and develops into new strains typically by just a single amino acid substitution.

The letter states that the pause potentially applies to six projects that range from studying the ecology of avian flu in live bird markets in Colombia to looking at drug - resistance mutations in seasonal influenza strains.

While this year's vaccine is a much better match to the circulating seasonal strains of influenza, the shifty nature of the virus and the need to pick the viruses used to make global vaccine stocks well before the onset of the flu season can make vaccine strain selection a shot in the dark.

Like many influenza virologists, John Steel of Emory University in Atlanta often uses a feeble lab strain of influenza in his studies of how seasonal flu spreads.

Thomas, PhD, an Associate Member in the Department of Immunology at St. Jude.

Seasonal flu vaccines may protect individuals not only against the strains of flu they contain but also against many additional types, according to a study published this week in mBio ®, the online open - access journal of the American Society for Microbiology.

The work, directed by researchers at St. Jude Children's Research Hospital in Memphis, Tenn., found that some study participants who reported receiving flu vaccines had a strong immune response not only against the seasonal H3N2 flu strain from 2010, when blood samples were collected for analysis, but also against flu subtypes never included in any vaccine formulation.

Russell said that he and his colleagues found that each year since 2002 new strains of influenza A (H3N2), the most infectious variety of seasonal flu, originated in «the east and Southeast Asian circulation network,» which spans from Malaysia and western Indonesia to Korea and Japan.
