The Corona vaccinations have been progressing very slowly for months. According to the Robert Koch Institute (RKI), 79.3 per cent of the Berlin population have been vaccinated against Corona at least once. A basic immunisation, which usually includes two vaccinations, has been given to 78.2 percent. 60.6 percent are boostered, i.e. have had a booster vaccination. A second booster vaccination, which the RKI recommends for people over 70, residents, caregivers and employees in nursing care as well as employees in medical facilities, has been given to 4.5 percent.
