Unvaccinated and vaccinated people should be concerned about the rapid rise of Delta, which now makes up at least 83% of sequenced cases in the US.
The more uncontrolled spread, the more risk of even more dangerous variants. Vaccination, masks, ventilation and distancing can stop Covid, including Delta. Variants remain the wild card for the trajectory of the pandemic. Delta may not be the worst strain the virus deals us.
We can reduce the risk of other dangerous variants by vaccinating widely and also tamping down spread.
