Covid-19: British group SAGE’s report suggests variants may challenge pandemic strategies

A British government advisory group has predicted a future in which Covid-19 will always be around, and recommends that authorities plan ahead for a more deadly variant or one that eludes vaccine protection. The Scientific Advisory Group for Emergencies (Sage) predicted that future variants could be resistant to vaccines by using a different spike protein to bind to human cells. Many Covid-19 vaccines work by recognising the spike protein, according to a report by the group published on July 26.
