Stang and coworkers have recently reported in the Journal that “RT-PCR test results as gold standard for assessing and controlling infectiousness fail”[1]. The authors analyzed two scenarios and used Ct25 and Ct30 as thresholds for infectiousness and conclude that more than the half of their patient cohort was unlikely to have been infectious, i.e. the… Continue reading Limited protection against #SARS-CoV-2 infection and virus transmission after mRNA #vaccination →

Epidemiologists are adjusting their expectations for the future course of the pandemic after data from a recent outbreak in Massachusetts in the US suggest that while vaccination remains highly protective against the worst consequences of infection, it may not be sufficient on its own to stop the spread of the delta variant. Testing conducted among… Continue reading Covid-19: #Delta infections threaten herd immunity #vaccine strategy →

SARS-CoV-2 variant B.1.617.2 (delta) is associated with higher viral loads [1] and increased transmissibility relative to other variants, as well as partial escape from polyclonal and monoclonal antibodies [2]. The emergence of the delta variant has been associated with increasing case counts and test-positivity rates, indicative of rapid community spread. Since early July 2021, SARS-CoV-2… Continue reading Vaccinated and unvaccinated individuals have similar viral #loads in communities with a high prevalence of the #SARS-CoV-2 delta variant →
