[h=3]Abstract[/h] Vaccine effectiveness (VE) against influenza B was derived separately for Victoria and Yamagata lineages across eight seasons (2010-11 to 2017-18) in Canada when trivalent influenza vaccine was predominantly used. VE was ≥50% regardless of lineage match to circulating viruses, except when the vaccine strain was unchanged from the prior season.
