Gigaohm Biological (25 Sept) Enriching the virus
It is exactly what we warned ………..they are forcing the virus to rapidly evolve.
S1 mutations cluster phylogenetically, suggests bursts of evolution
Mutations in S1 arising via within-host pressures result increase viral fitness and are enriched in the viral population by natural selection.
Although selection has not been primarily for antigenic drift, observed level of adaptability suggests its potential.
