The number of first doses administered is cumulative and it refers only to the total number of vaccine doses administered as first dose of 2-dose vaccination course products.
The number of complete primary courses administered is cumulative and it refers to the total number of primary courses administered defined according to the authorised schedule for each vaccine product at EU level (e.g. second dose of 2-dose vaccination course products, as well as first dose of single dose vaccination course products such as Janssen).
The number of booster doses administered is cumulative and based on the following definition of first, second and third boosters.
First booster: for surveillance purpose, this refers to the first additional dose of COVID-19 vaccine administered after the standard primary course. Therefore, the count and uptake estimates may include both first booster doses administered to immunocompetent persons and additional primary course doses administered to immunocompromised individuals.
Second booster: for surveillance purpose, this refers to the second additional dose of COVID-19 vaccine administered after the standard primary course. Therefore, the count and uptake estimates may include both second booster doses administered to immunocompetent persons and second additional doses administered to immunocompromised individuals after a standard primary course.
Third booster: for surveillance purpose, this refers to third additional doses of COVID-19 vaccines administered after the standard primary course. Therefore, the count and uptake estimates may include both third booster doses administered to immunocompetent persons and third additional doses administered to immunocompromised individuals after a standard primary course.
