Data on effectiveness of the BioNTech-/Pfizer COVID-19 vaccine in real-world settings are limited. In a study of 6,423 healthcare workers in Treviso Province, Italy, we estimated that, within the time intervals of 14-21 days from the first and at least 7 days from the second dose, vaccine effectiveness in preventing SARS-CoV-2 infection was 84% (95% confidence interval (CI): 40-96) and 95% (95% CI: 62-99), respectively. These results could support the ongoing vaccination campaigns by providing evidence for targeted communication.
