Coronavirus: Gut bacteria may trigger weaker immune response to Covid vaccine
In the study, Ishikawa and his colleagues took a stool sample and multiple blood samples from 96 healthy participants living in Okinawa, starting before the first dose of the vaccine, and ending a month after the second dose.
The team also found that individuals with a reduced T-cell response had higher expression of two genes, FOS and ATF3, prior to vaccination. Photo credit: IANS
