“Initial comparison of nasal swabs acquired from children living in vaccinated households revealed readily detectable SARS-CoV-2-specific IgG , especially when compared to the complete deficit of SARSCoV-2-specific antibody detected in the few nasal swabs we obtained from children in non-vaccinated households.”
Dr Ross Ked and others, from the University of Colorado Anschutz Medical Campus, in a pre-print article, Evidence for Aerosol Transfer of SARS-CoV2-specific Humoral Immunity, published on 28 April 2022
My take on it
We were warned that it might happen.
Then we were reassured that it couldn’t.
Now the research says that it does.
Mind you, the research only goes so far. It shows that vaccinated parents will engender a related immune response in their (unvaccinated) children, via air-borne antibody transfer; and that unvaccinated parents will not.
It remains to be seen what the longer term effects will be, for good or for ill.
