Oxford-AstraZeneca vaccine

The Oxford-AstraZeneca vaccine is designed to protect against COVID-19 by teaching the immune system to recognize the virus. It uses a harmless virus (a modified chimpanzee virus) to deliver genetic material from the COVID-19 virus, prompting the body to produce an immune response. This helps the immune system recognize and fight the actual virus if encountered later. It's stored at regular refrigerator temperatures, making it easier to distribute. The vaccine has been shown to be effective in reducing severe illness and hospitalizations caused by COVID-19.
