Newer coronavirus variants are less infectious to brain
The omicron BA.1 variant of SARS-CoV-2 is less infectious in the brain and triggers less inflammation in brain cells than the virus variant responsible for the first SARS-CoV-2 wave. This has been shown in research with hamsters and human brain cells by scientists from the Erasmus MC. ‘Good news, but no guarantees for the future.’
