COVID-19 vaccine dose numbers by top manufacturer 2021
As of March 9, 2021, there were pre-purchase agreements for over three billion doses of AstraZeneca/Oxford's vaccine. This vaccine is by far the most sought after COVID-19 vaccine, especially due to its ability to be stored at normal refrigerator temperatures, while other vaccines might need ultra cold storage. Although still in phase III of clinical trials and without approval, Novavax's vaccine is the one with the second highest number of orders worldwide.
