States struggle with vaccine pause as feds reassure public

But while those numbers are small, many of the people the vaccine has been targeted at are vulnerable: homeless people in Baltimore, homebound residents in the District of Columbia, the poor and uninsured in Massachusetts, rural residents in a number of states. All are populations easier to reach with a single dose than the two-dose regimen of the Pfizer and Moderna vaccines. About 10 million doses shipped to the states are now on shelves awaiting a decision. And many people who might not seek out a shot but could have been reached with mobile clinics and concerted outreach may be left behind, at least for now... In Lexington, Ky., a Johnson & Johnson clinic for Friday was canceled, leaving around 400 people without appointments. All were offered a last-minute option to get a Moderna vaccine, but only about 65 accepted the offer, said Kevin Hall, a spokesman for the Lexington-Fayette County Health Department. “This was a major hit to our planning,” said Mr. Hall, whose agency had already used the Johnson & Johnson vaccine for inmates and homeless people, and had planned to offer neighborhood clinics in the coming weeks. “The logistics of pulling off a first-dose and second-dose clinic become much, much more difficult.”
