With the massive increase in vaccine hesitancy worldwide, Chinese scientists have proposed passively inhaled COVID-19 mRNA vaccines based on viral shedding for the unvaccinated.
Chinese scientists Qin Xiang Ng and Wee Song Yeo carried out a study proposing passive inhaled mRNA vaccination for SARS-Cov-2 for those who are not vaccinated.
"We propose the massive and passive immunization of the at-risk population via cohorting with individuals who have recently contracted SARS-CoV-2, but are deemed non-infectious albeit reverse transcription-polymerase chain reaction (RT-PCR)-positive.
Testing RT-PCR positive would imply the continued spread of non-viable mRNA particles into the surroundings".
"Multiple studies have noted that individuals who has had SARS-CoV-2 for more than 10 days were non-infectious, though they remained RT-PCR-positive.
The above finding is in line with current US Centers for Disease Control and Prevention (CDC) guidance that “persons with mil...
