ChAdOx1-S

ChAdOx1-S is a COVID-19 vaccine developed by AstraZeneca and the University of Oxford. It uses a harmless virus, called a chimpanzee adenovirus, to deliver genetic instructions that teach the human body to recognize and fight the coronavirus. This helps your immune system prepare to defend against COVID-19 without causing the disease itself. The vaccine has been widely used globally and has been shown to provide effective protection when administered properly.
