A large team of researchers from the Centers for Disease Control and Prevention (CDC) and the US Department of Justice found in a study in a Texas prison that vaccinated inmates were infectious for exactly as long and as seriously as unvaccinated inmates.
This study can hardly be more official. The researchers were not critics of vaccination either.
They studied a Corona outbreak in a prison in Texas in July 2021. In the following weeks, regular smears and tests were taken from a selected group of inmates. The result: There is no difference whatsoever between the vaccinated and non-vaccinated inmates.
No statistically significant difference was detected in the duration of viral culture positivity between participants who were fully vaccinated (median: 5 days) compared with those who were not fully vaccinated.
