Gut's immune response in COVID-19 may not provide efficient protection of other organs

(Frontiers) COVID-19 can enter the body via the lungs and gut, and a new study suggests the gut's immune response alone may not provide adequate whole-body immunity from the virus. Blood samples analyzed from COVID-19 patients revealed that immune cells triggered by the gut's response to infection were limited in number when compared to immune cells triggered elsewhere in the body. While more research is needed, these findings could have implications for planned oral COVID-19 vaccines.
