Secreted IgA levels were higher (405 vs 300 ng/ml, p = 0.02) in group E2 compared to group E1 and moreover, in group E1 (p = 0.0008) were significantly higher compared to group C. This is probably a result of vaccination and the response of infection, but equally AuraShield L treatment in group E2 boosted IgA levels above E1 (p = 0.02). The gene discussed is CD79A; the disease is infection.
