The vaccination operation started one year ago on January 18, according to a statement by the Catholic charity organization Malteser Hilfsdienst on Tuesday (Jan. 18, 2022), which operates the vaccination center on behalf of the Berlin Health Administration. It is the largest vaccination center operated by Malteser in Germany. In Berlin, the first vaccination center began operation at the end of December 2020 in Treptow-Köpenick. However, along with four others, it has since been closed again. The vaccination center Messe on the exhibition grounds is thus the oldest one still in operation in Berlin.
