a – Survival chart (Immunized control is without HCA); b – Combo chart of AFC count and HA titer after administration of secretome c – Box plot of the antibody-producing cells (AFC) count in the spleen after administration of secretome; d – Box plot of the hemagglutinin (HA) titer in the blood serum after administration of secretome 
Statistical analysis using the Fisher's test for sample shares: 1 – significant difference compared to Positive Control (p ≤ 0.01); 

Statistical analysis using the Mann–Whitney–Wilcoxon U-test:  2 – significant difference compared to Immunized Control (p ≤ 0.05); 3 – significant difference compared to Immunized Control (p ≤ 0.01); 4 – significant difference compared to Thymalin (p ≤ 0.05); 5 – significant difference compared to Thymalin (p ≤ 0.01)
