Small RCT 60 healthcare workers in Iran, showing lower cases with treatment but without statistical significance. Once daily oral synbiotic capsule (Lactocare®) containing 1 billion CFU L. (Lactobacillus) casei, L. rhamnosus, Streptococcus thermophilus, Bifidobacterium breve, L. acidophilus, Bifidobacterium infantis, L. bulgaricus, and Fructooligosacharide.
The immune effects of probiotics are strain-specific.
respiratory symptoms, 73.3% lower, RR 0.27, p = 0.35, treatment 1 of 29 (3.4%), control 4 of 31 (12.9%), NNT 11.
risk of case, 85.3% lower, RR 0.15, p = 0.24, treatment 0 of 29 (0.0%), control 3 of 31 (9.7%), NNT 10, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).

Introduction: COVID-19 pandemic caused by the novel coronavirus SARS-CoV-2 increasingly involves people worldwide. Probiotics can improve immune system functions via different mechanisms. We proposed that Synbiotic Lactocare ® may also reduce SARS-Cov2 infection in high-risk medical staff working in COVID-19 hospital wards. Method: In a randomized, controlled trial, 60 hospital staff without any history of clinical or laboratory evidence of SARS-Cov2 infection were received either once-daily oral synbiotic capsule (Lactocare ® ) that contains 1 billion CFU/Cap of L. (Lactobacillus) casei, L.
