A new study, “Evidence for Aerosol Transfer of SARS-CoV2-specific Humoral Immunity” shows that vaccinated adults are more likely to transmit SARS-CoV-2 infection to their children who live in the same household. Researchers from the University of Colorado detected the presence of SARS-CoV-2 specific IgGs and IgAs in swab samples taken from children who live with “fully vaccinated” parents.
Children who live in unvaccinated households are less likely to have SARS-CoV-2 specific antibodies in their nasal passageways and saliva. This evidence shows that unvaccinated children could be developing specific immune responses to the spike proteins that vaccinated people are shedding through their skin and into the air.
