COVID - Incomplete Intestinal Flora and Vaccination

People lacking Bifidobacterium adolescentis in their intestinal flora showed subnormal antibody response to different COVID-19 vaccines. This was discovered in a cooperation between two independent research facilities at the University of HongKong.

Shenzhen News, December 3, 2021.

Joint research proved that over half of the people who received the Chinese SinoVac vaccine had a suboptimal antibody response. There was a close correlation between low antibody response and lack of a unique bacterium in our gut called Bifidobacterium adolescentis. Among BioNTech recipients, those who lacked Bifidobacterium adolescentis (and F. prausnitzii) also showed lower antibody response.

An evaluation given by a German medical journal (January 2021) is hinting at the use of antibiotics in some critical cases of Covid-19 and which was possibly leading to a disturbance of the intestinal flora.

The gut organ makes part of the human immune system and its cells can as well be infected by the corona virus. That is why a possible relation between intestinal flora on one side and antibody response to covid vaccines or the Long Covid sydrome on the other side cannot be excluded.
