Gut bacteria that break down a sugar called fucose could be dampening our immune response to the COVID-19 mRNA vaccine, according to a study led by researchers from the Okinawa Institute of Science and Technology.
The findings illustrate the important impact that the trillions of bacteria in our gut collectively called our 'gut microbiome' have on our immune health and add a missing piece to the puzzle of why vaccination varies in effectiveness from person to person
According to Okinawa Institute of Science and Technology researchers, gut bacteria that break down a sugar called fucose may be suppressing our immune response to the Covid-19 mRNA vaccine (OIST).
