Dr. Sabine Hazan on how Covid vaccines reduce number of Bifidobacteria

"I took my colleagues and I said: "I want your stool before and then month after the (Covid) vaccine."...I had the baseline of their stools, and then a month later the Bifidobacteria went down in all the patients except one patient. What was concerning is the persistence of that killing of the Bifidobacteria...We noticed with booster 1 the Bifidobacteria dropped and then booster2, I mean the second shot the Bifidobacteria kept dropping...The majority, one or two shots they're gonna bounce back and their Bifido's going to come back up and their microbiome is going to come back up. However there is a population that it's not coming back. These are the vax injuries."
