"The number of appointment bookings is increasing significantly at the moment," Andrea Ferber, head of the Johanniter vaccination center in the Ring-Center in Friedrichshain, told the German Press Agency (dpa) on Tuesday. Among those willing to be vaccinated are both younger people and older people over 60, Ferber said. For some of the patients it is the first booster, for others the second booster vaccination. According to the Association of Statutory Health Insurance Physicians in Berlin (KVB), doctors' offices will also receive the vaccine starting Tuesday. The KVB has published an address list on the Internet. In a Kreuzberg vaccination center, the first of these vaccinations had already been administered on Monday.
