Sharon, I doubt even the broadest definition of 'anti-vax' would include the authors of the aerosol transfer study. One small study isn't dogma, but it's an excellent and intriguing study.
"The vaccines against SARS-CoV-2 have maintained remarkable efficacy against severe
disease and death in those vaccinated regardless of variant emergence, Omicron included.
Less appreciated than the systemic immunity generated by the vaccines are the high levels of
antibody (IgG and IgA) found within the nasal cavity and saliva of vaccinees. This outcome is
found in both humans and primates, and in response to both mRNA and protein-based vaccines.
Respiratory transmission of viral infection is proof that oral/nasal cavity constituents can be
communicated through aerosols and/or respiratory droplets. As such, it would stand to reason
that antibody present within the oral/nasal environment may also be aerosolized to some
degree."
"To evaluate this hypothesis, we obtained nasal swabs from children living in
households in which parents or family members had varying degrees of SARS-CoV2-specifc
immunity, including those unvaccinated, vaccinated and COVID-19+. Initial comparison of nasal
swabs acquired from children living in vaccinated households revealed readily detectable
SARS-CoV-2-specific IgG (Fig 1E), especially when compared to the complete deficit of SARS-
CoV-2-specific antibody detected in the few nasal swabs we obtained from children in non-
vaccinated households. We then used the variation in parents’ levels of intranasal IgG as the
basis of stratification across all children’s samples. Log transformation of the data from thirty-
four adult-child pairs established antibody cut-offs for high vs low parental intranasal antibody
levels. Evaluation of samples in this fashion revealed that high intranasal IgG in vaccinated
parents was significantly associated (p-value = 0.01) with a 0.38 increase in the log transformed
intranasal IgG gMFIs within a child from the same household (Fig 1F). This significant positive
relationship was observed using either parametric or non-parametric analysis, and adjustments
for the correlation within household did not alter the conclusion. Though not statistically
significant, a similar trend of elevated IgA was found in the same samples."
