The Alpha variant saw the virus that causes Covid-19 evolve to be more transmissible. Whilst a lot of attention has been on the spike binding areas of the virus and the effectiveness of antibodies from either vaccine or prior infection, new research demonstrates how the virus evolved an ability to inhibit our bodies innate virus response once it has infected a cell.
