The new universal flu vaccine, which researchers say will only need to be administered once, has been found to be effective against a number of different types of influenza virus, including the deadly avian flu and pandemic swine flu strains.
Flu viruses are highly changeable so elderly people and pregnant women, who are particularly vulnerable to the illness, are currently given new vaccinations each year to ensure they are protected.
Small-scale clinical trials on the new vaccine – known as Flu-v – have shown that it can significantly reduce infection and also cut the severity of symptoms.
Results of the trials will be presented at an international conference this week by SEEK, the London-based drug development company behind the vaccine.
