25 November 2021, Saxony-Anhalt, Magdeburg: Minister President Reiner Haseloff (CDU) receives his booster vaccination from doctor Susanne G?bel at the Wittenberg vaccination centre. "After discussions with doctors, I deliberately decided to have a booster vaccination with the Moderna vaccine after two Biontech vaccinations, as these cross-vaccinations are particularly effective," said the CDU politician.
