• Between December 8, 2020, and February 22, 2021, receipt of the first dose of the Pfizer-BioNTech vaccine in Scotland was associated with a vaccine effectiveness of 91% for reduced COVID-19 hospital admission at 28–34 days post-vaccination, and 88% for the Oxford-AstraZeneca vaccine. Over the study period, a total of 1,331,993 individuals who had not previously tested positive for SARS-CoV-2 were vaccinated. Vaccine efficacy against hospital admission due to COVID-19 was similar (83%) when restricting the analysis to those aged 80 years and older.
