Scientists are working on a new universal Flu vaccine that would protect recipients from a wider range of strains for a longer period of time. This year’s vaccine is the same that was used last year for the H3N2 subtype, unfortunately the effectiveness of the vaccine which was 20-30% effective last year is now only 10% effective. Clinical trials are currently underway for the universal vaccine but will likely take 10 years before it’s available for use.
Do you get a yearly flu shot? Does it keep the flu bug away?
