What Happens to the Microbiome After Vaccination?
In today’s short clip from “Microbiome Insights: Health Benefits, Probiotics, and Medical Breakthroughs with Dr. Sabine Hazan”, Dr. Hazan shares findings from her research looking at how the microbiome can change after vaccination.
She explains that in patients tested before and after vaccination, her team observed a significant drop in bifidobacteria — an important group of gut microbes linked to digestion, immune balance, and overall gut health. What stood out most was that in some cases, this change wasn’t temporary. Even months later, bifidobacteria levels hadn’t recovered.
Dr. Hazan also connects these patterns to what she’s seen clinically when working with long-haul patients and those experiencing vaccine-related complications — showing how closely gut health and recovery may be linked.
This clip offers an important reminder of just how sensitive and influential the microbiome is, and why protecting and supporting it matters.
