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

New cases of Covid-19 are declining across most of the US, even in some states with vaccine-hesitant populations. 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. Case totals nationally have declined in a fortnight from a seven-day average of nearly 21,000 on 29 May to 14,315 on Saturday, according to data from Johns Hopkins University. For weeks, states and cities have been ending virus restrictions and mask mandates, even indoors.
