Fear that Johnson & Johnson pause could heighten vaccine hesitancy in US

A deflating pattern is emerging in rural, conservative and vaccine-hesitant states as authorities worry that stakes could not be higher in those same communities

Teton county, Wyoming, is at the vanguard of America's Covid-19 vaccination campaign - but it isn't celebrating.

The county has vaccinated far more people proportionally than in most of America - 39% - compared to less than a quarter nationally. Local authorities are concerned they may have hit a saturation point. Vast, rural and conservative Wyoming is one of the most vaccine hesitant places in the nation, and fewer people are signing up for vaccine clinics. Similar patterns are emerging across the US.
