Researchers believe they may be able to produce a universal flu vaccine using synthetic protein nanoparticles. The vaccine has been successful in animal testing, and scientists say it could require fewer updates and protect against flu strains yet to emerge in humans. "In theory, a new version could be produced quickly once a new pandemic virus had been identified, or a new seasonal variant started to circulate," said University of Oxford researcher Sarah Gilbert, who was not involved in the study.
