Scientists a step closer to universal flu vaccine

Researchers say they are closer to developing a vaccine to give life-long protection against any type of flu, after promising trials in animals, BBC News reported.

Two separate US teams found success with an approach that homes in on a stable part of the flu virus.

That should prevent the problem with existing flu vaccines, which must be given each year because they focus on the mutating part of the virus.

The studies have been published in Science journal and Nature Medicine.

Further research is now needed to confirm that the method will work in humans.

Meanwhile, experts say people should continue to receive an annual flu jab, because vaccination is still the best way to protect against infection.
