This past summer, the Centers for Disease Control (CDC) funded a study on the transmission potential of vaccinated and unvaccinated persons infected with SARS-CoV-2 at a federal prison in Texas.

The study, titled “Transmission potential of vaccinated and unvaccinated persons infected with the SARS-CoV-2 Delta variant in a federal prison, July—August 2021,” found absolutely no difference between the vaccinated and unvaccinated inmates, concluding:

“As this field continues to develop, clinicians and public health practitioners should consider vaccinated persons who become infected with SARS-CoV-2 to be no less infectious than unvaccinated persons. These findings are critically important, especially in congregate settings where viral transmission can lead to large outbreaks.”

Undoubtedly, the analysis, which occurred during a SARS-CoV-2 Delta variant outbreak, detected no statistically significant difference in the duration of viral culture positivity between fully vaccinated participants (median: 5 days) and those who were not fully vaccinated.
