SEATTLE – When Seattle's largest health care system got a mandate from Washington state to create a mass COVID-19 vaccination site, organizers knew that gathering enough volunteers would be almost as crucial as the vaccine itself. “We could not do this without volunteers,” said Renee Rassilyer-Bomers, chief quality officer for Swedish Health Services and head of its vaccination site at Seattle University. “The sheer volume and number of folks that we wanted to be able to serve and bring in requires … 320 individuals each day." As states ramp up vaccination distribution in the fight against the coronavirus, volunteers are needed to do everything from direct traffic to check people in so vaccination sites run smoothly.
