Study explains why Omicron infections are less likely to cause severe disease

Why the Omicron variant causes less severe disease

A new study shows that the SARS-CoV-2 Omicron variant is less effective than Delta at blocking a cellular defense mechanism against viruses, the so-called 'interferon response'. Moreover, cell culture findings indicate that eight important COVID-19 drugs and drug candidates remain effective against Omicron.

Study explains why Omicron infections are less likely to cause severe disease

A new study by researchers from the University of Kent and the Goethe University Frankfurt shows that the SARS-CoV-2 Omicron variant is less effective than Delta at blocking a cellular defense mechanism against viruses, the so-called “interferon response”.

Why the omicron variant causes less severe disease

The SARS-CoV-2 omicron variant causes less severe disease than Delta although it is better at escaping immune protection by vaccinations and previous infections. The reasons for this have so far remained elusive.
