Summary Context

Influenza effectiveness findings may require consideration of other agent-host and immuno-epidemiologic influences on vaccine performance beyond antigenic match, including viral genomic variation, repeat vaccination, birth (immunological) cohort effects, and potential within-season waning of vaccine protection.

Comments

This study examined yet more failed results in seasonal flu vaccination, and found that strains/ antigenic match did not tell the whole story.

Abstract or Results, Key Passages

“The VE against A(H1N1)pdm09 was also lower for participants consecutively vaccinated during both the current and prior seasons (41%; 95% CI, 18%–57%) than for those vaccinated during the current season only (75%; 95% CI, 45%–88%)”
