Baseline gut microbiota and metabolome predict durable immunogenicity to SARS-CoV-2 vaccines

Signal Transduction and Targeted Therapy, 2023
The role of gut microbiota in modulating the durability of COVID-19 vaccine immunity is yet to be characterised. In this cohort study, we collected blood and stool samples of 121 BNT162b2 and 40 CoronaVac vaccinees at baseline, 1 month, and 6 months post
