Clinical evaluation of the efficacy of Bioaron C®, in terms of the frequency and duration of infection in children with recurrent upper respiratory tract infections, was performed in a clinical hospital in Moscow.

In the T-cell immunity test, an increase in the relative and total T-cell counts (CD3+, CD4+, CD8) was seen; there was a statistically significant increase in the relative number of CD3+ and CD4+ and total T-cell count (CD4+, CD8) as well. A statistically significant reduction in the relative number of CD16+ cells was seen. In the drug safety tests, no biochemical abnormalities in blood parameters have been seen.
