Andrea Sadowski, RN, BSN, waits in the observation station for 15 minutes at UCSF Benioff Childrenâs Hospital Oakland after being administered the Pfizer COVID-19 vaccine. When asked how she was feeling, she said, âExcited. When I heard that we had the opportunity to get it I jumped on it immediately. Itâs awesome.
