Across the country, a university researcher in Phoenix teamed up with a company behind comic books fighting Islamic extremism to produce dance-inducing animated stories in Spanish that aim to smash conspiracy theories hindering Latinos from getting inoculated. And in San Diego, former refugees, Latinos and Black activists initially hired by health officials as contact tracers are calling back the people they reached about COVID-19 exposure to talk about the shots.
