A single vaccine has been shown to protect people from both SARS-CoV-2 and influenza viruses and with a higher effectiveness than vaccines that target one or the other, the pharmaceutical company Moderna has announced.
Moderna said that the vaccine was more effective at providing immunity to adults over the age of 50 than competing flu and COVID-19 shots.
Combination vaccines can have big public-health benefits, but they are often time-consuming and expensive to develop. Moderna's latest rapid success shows that RNA can help to overcome some of these difficulties, says James Thaventhiran, a clinical immunologist at the University of Cambridge, UK.
This is a great example of why the technology is exciting, he says, adding that the combination vaccines using mRNA are just the beginning for RNA technology.
