Three American siblings have received their first dose of the Pfizer-BioNTech COVID-19 vaccine as part of global clinical trials for young children. Christian Bui, 3, and Sloan Bui, 14 months, both got the initial shot on Monday at Ochsner Hospital for Children in Jefferson, Louisiana, just outside New Orleans. Their older sister, 6-year-old Ellie Bui, got her first dose earlier this month. The children's parents, Dr. Cuong "CJ" Bui and Dr. Erin Biro, are neurosurgeons at Ochsner Medical Center in Jefferson and discussed with ABC News their decision to have all their kids participate in the study. "For us, our kids living safely in a world where we don't have to worry about them getting sick from COVID, being able to go to school, have playdates with their friends, we feel strongly that vaccine is what is going to get us to those goals," Biro said.
