PMBL in prevention of LRTI

The clinical trial performed by Rossi demonstrated a significant reduction of number of LRTI in patients treated with PMBL as compared to patients treated with Chemical lysates or control group. This was noticed during treatment period and follow-up. Additionally, the need to use antibiotics was less with patients treated with PMBL as compared to those treated with chemical lysates.
