“What we discovered was that, whereas there have been variations between individuals who had COVID-19 and those that weren’t in poor health, the largest distinction from others was seen in those that had been administered antibiotics,” mentioned Blaser, the Henry Rutgers Chair of the Human Microbiome at Rutgers College, in addition to a director of the college’s Middle for Superior Biotechnology and Drugs.

The examine’s findings might finally result in the event of probiotics particularly for individuals who come down with COVID, the authors state.
