Effect of Lactobacillus on the Microbiome of Household Contacts Exposed to COVID-19 - Clinical Trial
What is the Purpose of this Study?
We are doing this study to learn more about how the probiotic, LGG, affects the microbiome (the microorganisms that live in and on the human body) in people that have household contact with someone that has COVID-19.
LGG is a type of probiotic, which is made of live bacteria that can improve gut health and potentially improve the immune system and prevent infections.
