📢 New preprint! We compared SARS-CoV-2 variants in an epithelium model grown at a temperature found in nasal passages (33°C). Omicron replicated to higher levels, caused more cilia damage, but induced less interferon than previous variants. Thus, Omicron could be fast but stealthy!
Stealth replication of SARS-CoV-2 Omicron in the nasal epithelium at physiological temperature
The COVID-19 pandemic was marked by successive waves of SARS-CoV-2 variants with distinct properties. The Omicron variant that emerged in late 2021 showed a major antigenic shift and rapidly spread wo...

The impact of the PEPFAR funding freeze on HIV deaths and infections: a mathematical modelling study of seven countries in sub-Saharan Africa
The sudden cessation of PEPFAR funding likely results in tens of thousands of HIV
deaths and new infections. These losses of life and health should compel the United
States government to rapidly and f...

Estimated number of lives directly saved by COVID-19 vaccination programmes in the WHO European Region from December, 2020, to March, 2023: a retrospective surveillance study
Over nearly 2·5 years, most lives saved by COVID-19 vaccination were in older adults
by first booster dose and during the Omicron period, reinforcing the importance of
up-to-date vaccination among the...
