A universal vaccine that protects against all strains of the flu virus may be a step closer.
The annual flu vaccine currently protects against four strains of the virus which scientists believe are most likely to be in circulation in the coming winter.
But a vaccine that protects us from all types of flu — which kills between 10,000 and 30,000 people a year in the UK — is one of the holy grails of medicine.
There are three different types of flu virus affecting humans — A, B and C, with various sub-types (including 29 of type A alone) which may mutate over time.
Scientists look at patterns of flu in other parts of the world to help decide which strains to include in the annual flu vaccine given here — but that has to be months in advance, to allow time for the vaccine to be made.
The vaccine will include two A strains and two B strains thought most likely to be circulating in the coming winter (type C strains are not included, as they usually cause only mild symptoms).
But scientists don't always get the selection right. In 2014/15, for instance, the flu jab ended up being only 3 per cent effective at preventing cases of flu because the strains contained in the vaccine were so out-of-kilter with what was circulating.
In 2015, almost 30,000 people in England and Wales alone died of flu and pneumonia, compared with 25,000 the year before.
Now, by adopting a new approach, scientists at the U.S. National Institute of Allergy and Infectious Diseases have made a 'major step forward' in the search for a universal flu vaccine. Current vaccines target the 'head' of proteins called hemagglutinins, which are found on the surface of the flu virus.

SeekAndFind : " This 'head' varies between strains and changes over time — which is one reason why the vaccine must be updated each year.
The new research focuses on the 'stem' of the protein.

I’m happy to wait a couple of years on this one.
Big Pharma is completely untrustworthy.
I ,too, will wait for more information is available about this influenza "vaccine".
Agreed that there is no information about the prospects of another mRNA mentioned.
As far as mRNA vaccines are concerned, I believe that the FDA/CDC/Big Pharma intentionally failed address safety concerns regarding the covid "vaccine"
when they initially tried to hide the clinical studies for some 72 years before court ordered releasing that information.
That alone should mean that the jab participants were uninformed and should be grounds to invalidate Pharma from civil lawsuits.
In court, that would be considered exculpatory evidence that was not released, making participants "uninformed", thus invalidating the protections offered by FDA/CDC cabal with Big Pharma from civil lawsuits.
Great comment.
