These researchers show evidence that Mrna vaccination can transmit passively via respiration.

No evidence is shown in the paper
“Passive inhaled mRNA vaccination for SARS-Cov-2”.
The researchers are proposing that ‘passive’ immunization occur against COVID by mRNA vaccine. As I read it, the author calls this type of immunity ‘passive’ whereas immunity against the actual virus would cause ‘active’ immunity.
The researchers are suggesting that an inhalation type of mRNA vaccine be prepared for COVID, as inhalation immunization has been described and trialed (but not marketed) previously, as described in the review https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7471058/
“Many studies have focused on the development of RNA delivery vectors, but the translation of these vectors into suitable dosage forms for clinical application is currently lacking. Here, we summarize the critical steps for the development of successful pulmonary RNA delivery system (Figure 2 , Key Figure) and discuss the areas/factors that should be focused on.”
mRNA is notoriously unstable. It would need a delivery system, like lipsomes, to hide it to get it into the cells, methinks.
Thanks for the informed word, I appreciate it. :-)
