FILE – In this Jan. 24, 2021, file photo, a worker at left checks in with people sitting in an observation area after they were given the first of two doses of the Pfizer vaccine for COVID-19 in Seattle. Governors and health officials have been reluctant to sign on to a Biden administration plan to open 100 federally supported vaccination sites by the end of February. With vaccine supplies running tight, they want assurances that the doses will come from a separate federal supply and not their own.
