1. Abstract:
"SARS-CoV-2 501Y.V2, a novel lineage of the coronavirus causing COVID-19, contains multiple mutations within two immunodominant domains of the spike protein. Here we show that this lineage exhibits complete escape from three classes of therapeutically relevant monoclonal antibodies. Furthermore 501Y.V2 shows substantial or complete escape from neutralizing antibodies in COVID-19 convalescent plasma. These data highlight the prospect of reinfection with antigenically distinct variants and may foreshadow reduced efficacy of current spike-based vaccines."

3. A key takeaway, for me:
Evolutionary paths for covid-19 that would normally be very unlikely become more and more likely as more people get infected with the virus, providing a large-scale, global playground for experimentation via random mutation. Random evolutionary events that would normally be rare become more and more likely as the numbers grow large enough.
