Discovery points to a new path toward a universal flu vaccine

Flu vaccines can be something of a shot in the dark. Not only must they be given yearly, there’s no guarantee the strains against which they protect will be the ones circulating once the season arrives. New research by Rockefeller University scientists suggests it may be possible to harness a previously unknown mechanism within the immune system to create more effective and efficient vaccines against this ever-mutating virus.

The 2014-2015 flu vaccine didn’t work as well compared to previous years because the H3N2 virus recently acquired a mutation that concealed the infection from the immune system. A new study reveals the major viral mutation responsible for the mismatch between the vaccine strain and circulating strains. The research will help guide the selection of viral strains for future seasonal flu vaccines.


‘Virtual virus’ unfolds the flu on a CPU

The flu virus can be pretty nasty — it’s quick to evolve — which means yearly flu shots are needed and then it’s only a guess to which strain will be the most prevalent. Well new research aims to change all that, by combining experimental data from X-ray crystallography, NMR spectroscopy, cryoelectron microscopy and lipidomics (the study of cellular lipid networks), researchers have built a complete model of the outer envelope of an influenza A virion for the first time. So would that make it a computer virus, virus?


Designing a better flu vaccine

We all hate getting sick and the seasonal flu vaccine can help prevent a time of serious illness. Unfortunately the vaccine is usually an educated guess as to which strains of the flu are going to be most prevalent that year. Well now an international team of researchers has shown that it may be possible to improve the effectiveness of the seasonal flu vaccine by ‘pre-empting’ the evolution of the influenza virus.


Lab Made Flu Coming to a Outbreak Near You!

Spanish Flu outbreak of 1918

Forgive the alarmist title, I had to do it. Researchers have created a genetically engineered version of the flu, similar to the spanish flu that killed roughly 50 million people in 1918. Don’t worry, it’s not as bad as it sounds, that is until someone sneezes and drops the vial… but what are the odds that would… umm… happen.

Truthfully there is already a war coming. If anyone remembers the swine flu outbreak a few years back, you know what I am talking about — for those of you who had it, including yours truly, you know how horrible it can be. Swine flu or H1N1 was a supercharged flu that was 95% or so genetically different from the flu we have typically seen. This lead to all sorts of fun and horrid complications from the outbreak due to the fact it was something the body had never really seen before.
