Figure 11 illustrates the number of COVID 19 vaccine doses administered per 100 persons in the EU27 plus three EEA countries, which are ranked according to their vaccination progress by mid-2021. As the primary course of vaccination for two of the main COVID 19 vaccines (Pfizer-BioNTech and Moderna) consists of two doses, and one or two booster doses are recommended in most Member States, the number of administered vaccine doses per 100 persons can exceed 100.
The graph shows a substantial variation between countries: by mid-2021, the country with the slowest progress represented only one-fifth of the progress in the best-performing country. Subsequent developments did not significantly affect their relative progress, albeit with some notable drops in vaccination progress (e.g. Hungary) as well as catch-ups (e.g. Latvia). The second half of 2021 saw a general decline in vaccination progress with some exceptions. Vaccination progress in general plateaued during the first half of 2022, as most of the population had already been double-jabbed. By mid-2022, most of the countries were able to vaccinate a large part of their population, with 25 of EU27 countries reaching above 100 doses per 100 persons and 9 of EU27 reaching above 200 doses per 100 persons.
