A new study out of McMaster University challenges reports out of the U.S. about the effectiveness of nasal sprays in preventing the flu.
Findings published in the Annals of Internal Medicine show that the nose spray had a similar effect to the standard flu shot.
Lead Author Dr. Mark Loeb says he conducted a three year blinded trial that put both methods of vaccination to the test in Hudderite communities.
“We found that roughly about 5 per cent in each group got the flu.”
The Centers for Disease Control’s Advisory Committee on Immunization Practice previously recommended that nasal sprays be dropped for the 2016-2017 flu season.
