In December 2020, Klaus Reinhardt, president of the German Medical Association, said that a review period of four weeks for a Covid vaccine was too long. A spokesperson for the Federal Ministry of Health answered that the care and reliability of the vaccine had oberste Priorität, top priority. The headline in the Deutsches Ärzteblatt on 4 December 2020 was Bei Impfstoffzulassung gilt Sorgfalt vor Schnelligkeit. In vaccine approval, care comes before speed.
