Single radial hemolysis (SRH) response: MF59-adjuvanted H5N1 subunit influenza vaccine formulations and age cohort

Numbers in parenthesis are two-sided 95% confidence intervals; Seroprotection = SRH ≥25mm2; Seroconversion = negative pre-vaccination serum (i.e., SRH titer ≤ 4mm2) and post-vaccination SRH area ≥25 mm2 or significant increase (at least a 50% increase in SRH area in subjects who were positive pre-vaccination, i.e., SRH area >4mm2); HA, hemagglutinin; GMA, geometric mean area; GMR, the geometric mean of the ratio over baseline
