"To us, it was the beginning of the end of the pandemic,” said Glen Griesheim, the chief operating officer and chief nursing officer at St. Mary-Corwin. Since then, the hospital has doled out approximately 2,000 doses at its two vaccination sites at the hospital and in Pueblo West on Spaulding Avenue. That’s part of the 27,454 first doses and 17,909 second doses that have been administered in Pueblo County as of Feb. 25, according to the Pueblo Department of Health and Environment. Statewide, 495,961 people have received two doses as of March 1, according to the Colorado Department of Public Health and Environment. The county health department estimates it has vaccinated about 40% of the county’s population of people aged 65 years or older at its mass vaccination site at the Pueblo Mall. That doesn’t include efforts by organizations such as St. Mary Corwin at other sites.
