Comparison of SCRs and SPRs by age groups. a Bar graphs illustrating seroconversion rates (SCRs) against each of the four vaccine strains, young versus old age groups as indicated. CBER licensure criteria are indicated by two horizonal dotted lines. b Bar graphs illustrating seroprotection rate (SPRs) against each of the four strains, young versus old age groups as indicated. CBER licensure criteria are indicated by two horizonal dotted lines. Open bars, pre-vaccination SPRs; Gray colored bars, post-vaccination SPRs. *P < 0.05 post-vaccination SPR against B/Victoria between the young and old age groups; #P < 0.001 pre-vaccination SPR against B/Yamagata between the young and old age groups; △P < 0.01 post-vaccination SPR against B/Yamagata between the young and old age groups
