Scientists have developed a universal flu vaccine that, when tested in mice, protected the animals against eight different flu strains, according to research published in mBio and covered by HealthDay.
This could be significant for researchers and flu-sufferers alike if the vaccine works similarly in humans. Currently, a new flu vaccine is developed annually based on predictions of what the most common flu strain will be in the next season.
"What we have done is design a strategy where you don't have to think about matching the vaccine antigen to the virus at all," Jeffery Taubenberger, MD, PhD, the study's lead investigator said, according to HealthDay.
In the mice test, the vaccine was effective for at least six months and worked well in older mice.
"These initial findings are very positive, and suggest a promising and practical strategy for developing a vaccine with amazing, broad protection," Dr. Taubenberger said.
