BACKGROUND Two antigenically distinct influenza B lineages have cocirculated since 2001, yet trivalent influenza vaccines (TIVs) contain 1 influenza B antigen, meaning lineage mismatch with the vaccine is frequent. We assessed a candidate inactivated quadrivalent influenza vaccine (QIV) containing both B lineages vs TIV in healthy children aged 3-17 years.(More)
BACKGROUND We aimed to compare AS03-adjuvanted inactivated trivalent influenza vaccine (TIV) with non-adjuvanted TIV for seasonal influenza prevention in elderly people. METHODS We did a randomised trial in 15 countries worldwide during the 2008-09 (year 1) and 2009-10 (year 2) influenza seasons. Eligible participants aged at least 65 years who were not(More)
BACKGROUND Because inactivated trivalent influenza vaccines (TIVs) contain 1 influenza B strain, whereas 2 lineages may co-circulate, B lineage mismatch is frequent. We assessed an inactivated quadrivalent influenza vaccine (QIV) containing both B lineages versus TIV in young children. METHODS Children aged 18-47 months who had received 2 doses of TIV in(More)
