A universal flu vaccine — one that provides immunity against every strain of the influenza virus for multiple years — is the holy grail of flu research. It would be a medical breakthrough on the order of penicillin, with the potential to save hundreds of thousands of lives every year. And scientists just got one crucial step closer to making it a reality.
Two separate groups of scientists published papers this week demonstrating that a new type of flu vaccine can provide protection against multiple strains of the disease, rather than just one. Though a truly universal flu vaccine that could be given to humans remains years away, infectious disease experts hailed the new findings as a major breakthrough.
“These are very good papers. There are no problems with them,” Dr. Peter Palese, a renowned flu expert at Mount Sinai Hospital in New York, told The Huffington Post. “What we need to do now is put [these vaccines] in humans and see if they work. That’s the only question at this point.”
