When the Mainz biotech company Biontech and its partner, the American pharmaceutical giant Pfizer, announced three weeks ago that they had developed an effective corona vaccine, the news went around the world like a promise of salvation.
Shortly afterwards, other manufacturers registered promising vaccines, and the EU alone secured around 1.3 billion vaccine doses with pre-orders.
Great Britain began mass vaccination of the population last Tuesday as the first country in Europe, and preparations are in full swing in other countries as well. In Germany it should be so far on December 27th. The end of the pandemic seems to be within reach, the light at the end of the tunnel is shining brighter and brighter. But it is tied to one condition: the willingness of the population to be vaccinated.
