New preprint study that examined exhaled breathing finds that vaccination status made no difference in viral particle spreading of SARS-CoV-2.
A first-of-its-kind preprint study, partly funded by the NIH, examined how many virus particles an individual is exhaling into the environment while they breathe over the course of their SARS-CoV-2 infection.
The study found that “vaccinated and unvaccinated participants exhaled similar numbers of SARS-CoV-2 RNA copies, when accounting for age, sex, presence of co-morbidities, days since symptom onset and symptom severity.”
