Covid cases fall across US but experts warn of dangers of vaccine hesitancy

Health experts emphasize need for even those who have had disease to get inoculated

But almost all states where cases are rising have lower-than-average vaccination rates and experts warned on Sunday that relief from the coronavirus pandemic could be fleeting in regions where few people get inoculated.
