Authored by Marina Zhang: Works by gastroenterologist Dr. Sabine Hazan, the CEO of ProgenaBiome, a microbiome genomic research laboratory, found that after COVID-19 vaccination, people's Bifidobacteria levels can fall by as much as 90 percent. Some of her unpublished data found that Bifidobacteria levels are negligible in vaccinated people.
Bifidobacteria are among the first microbes to colonize a baby's gastrointestinal tract as he or she passes through the mother's birth canal. They are believed to exert positive health effects on their host.
Bifidobacteria interact with the immune system, and their presence is linked with improved immunity against pathogens and cancer.
