Sniffle be gone! This year’s flu shot is rumored to be more effective than many in years past as it covers four strains of the influenza virus. Though news that this year’s vaccine may provide more coverage is certainly welcome, it still doesn’t solve the problem of the persistent nature of the flu itself. DNews host Julia Wilde explained exactly why it is so difficult to create a vaccine that would eradicate the flu once and for all. She noted that “influenza is a mutating virus, which up until now researchers have only been able to treat strain by strain. Since scientists hypothesize which strain will be strongest each year, the effectiveness of the vaccine can be questionable.” However, we might not have to wait much longer to find a cure-all flu vaccine; earlier this year, TIME reported that researchers are working on a new vaccine using a part of the influenza virus that does not mutate as easily as the protein hemagglutinin, which is currently used in the flu vaccine.
