Vaccines are vital in combating the COVID-19 pandemic. The results of this study show no difference between the Pfizer-BioNTech and Oxford-AstraZeneca vaccines in the rate of mortality. However, the number of vaccine doses was significantly associated with a lower risk of mortality. Future studies should examine the effectiveness of different COVID-19 vaccines using real-world data and more robust designs.
