All this portends a more uneven pandemic, says Dr. Fernando Holguin, a pulmonologist and critical care doctor at the Latino Research and Policy Center at the Colorado School of Public Health. He worries cases, hospitalizations and deaths will keep flaring up in less-vaccinated communities, especially predominantly Hispanic communities in parts of Colorado or other states where overall vaccination rates are poor. "They're at risk, especially moving into the fall of seeing increasing waves of infections. I think it is really critical that people really become vaccinated," Holguin said.
