New paper published by Microbiome Vaccine Safety Project: 'Do gut microbiota mediate adverse vaccine reaction?'

Do gut microbiota mediate adverse vaccine reaction?

"It is possible that the proposed study would suggest stool and meconium microbial 16S rRNA testing be used pre-vaccination in order to determine microbial diversity and potentially assess risk of adverse vaccine reaction."

Also, two (2) new papers have been published this week, strengthening the link between gut microbiota and autism symptoms:

Human Gut Microbiota from Autism Spectrum Disorder Promote Behavioral Symptoms in Mice

"To test the effect of the gut microbiome on behavior, Sarkis Mazmanian, a microbiologist at the California Institute of Technology (Caltech) in Pasadena, and collaborators put fecal samples from children with and without autism into the stomachs of germ-free mice, which had no microbiomes of their own. The researchers then mated pairs of mice colonized with the same microbiomes, so their offspring would be exposed to a set of human microbes early in development."

"the products of gut microbes might somehow change autism risk by influencing what forms of proteins are made in the brain"

"In particular, mice harboring microbes from people with autism had lower levels of taurine and 5-aminovaleric acid (5AV), molecules that are known to bind to neurons and inhibit their activity."

Gastrointestinal dysfunction in patients and mice expressing the autism‐associated R451C mutation in neuroligin‐3

Note: It's said there's no such thing as a genetic epidemic. To chalk autism up to genes in disregard of environment is an apathetic view of the excruciating problem.

New research:
"We know the brain and gut share many of the same neurons and now for the first time we've confirmed that they also share autism-related gene mutations,"

Meanwhile, last month's new research:
Long-term benefit of Microbiota Transfer Therapy on autism symptoms and gut microbiota
