Side Effects Public Media Two volunteers at the University of Iowa mobile clinic set up a COVID-19 vaccination station at the Broadway Neighborhood Center in Iowa City. On a hot evening at the Broadway Neighborhood Center in Iowa City, home to the University of Iowa, student volunteers set up a mobile COVID vaccination clinic among the apartment complexes that house many immigrant and refugee families.

"It's really about talking to people and seeing if you can find them where they're at and encourage them to come over," he said.
