Vaccine effectiveness against lineage matched and mismatched influenza B viruses across 8 seasons in Canada, 2010-11 to 2017-18.
CLINICAL INFECTIOUS DISEASES(2019)
摘要
Vaccine effectiveness (VE) against influenza B was derived separately for Victoria and Yamagata lineages across 8 seasons (2010-2011 to 2017-2018) 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.
