for Pfizer-BioNTech vaccines with demonstrated efficacy of 52% after the first dose, there was no clear advantage for delaying the second dose beyond the 3-week tested schedule, unless the efficacy of the first dose did not wane over time. Our findings underscore the importance of quantifying the durability of vaccine-induced protection after the first dose as well as vaccine efficacy against infection in order to determine the optimal time interval between the two doses.
