Three Black students who helped develop the first COVID-19 vaccine reunited for the first time since the early pandemic days. According to CNN , Olubukola Abiona, Geoffrey Hutchinson and Cynthia Ziwawo were among the dozens of scientists who helped develop the vaccines at the Vaccine Research Center of the National Institutes of Health in Bethesda, Maryland. Working in Dr. Barney Graham’s lab at the research center, the students became a major part of the global effort to control the pandemic. “We knew we were doing things that were important, but then it was like ‘Oh, wow, this is really big,'” Ziwawo told CNN.
