HI titers and GMI at day 28 after first immunization in BALB/c mice. (a-d) The serum HI titers were detected by HI against H1N1, H3N2, BV, and BY at day 28. The data represent geometric mean with 95% CI. (e) Dynamic changes in GMI at various time points. (f) The SCRs for H1N1, H3N2, BY, and BV types. The dotted line indicates HI titers of 1:40 which are suggested to indicate a probability of clinical protection of at least 50%. This titer serves as a threshold for predicting protection. N = 9 to 12. *p < 0.05, **p < 0.01, ***p < 0.001.
