SAN FRANCISCO (AP) — As interest dwindles in mass coronavirus vaccination sites in the U.S., local health offices and other providers are ramping up efforts to find and reach homebound people who can’t travel for a shot. Victoria McAllister of Hayward, California has ruptured discs that could slice her spinal cord with a wrong move, so she was thrilled when her San Francisco Bay Area health department brought the vaccine to her. California and Pennsylvania are among states coordinating efforts to provide vaccinations in homes. National advocates for seniors and people with disabilities say there should be more robust plans to inoculate the millions of people in those groups.
