“Discussion: In our study, mean viral loads as measured by Ct-value were similar for large numbers of vaccinated and unvaccinated individuals infected with SARS-Cov-2 during the Delta surge, regardless of symptom status, at two distinct California testing sites ...
Two recent studies document that vaccinated individuals can transmit infection to vaccinated or unvaccinated persons even though they may show faster decay of viral loads and remain infectious for shorter periods of time than unvaccinated individuals ...
