Federal Health Minister Jens Spahn (CDU) said on July 21, 2021: “Well first of all, we still have comparatively very low numbers. And the question that we should all be concerned with, as I would like to advertise, is this as we keep it as low as possible, as long as possible. If this continues to develop as it has in the last three or four weeks, we have, as of now, a doubling time of about 10.12 days. That’s the problem with the exponential Growth that is so difficult to imagine. We are now at 11, 12 incidence. If this continues to double every 12 days, then in September we will exceed 400, in October 800 incidence. So now the question is, what does that actually mean with the vaccination quota for intensive care and hospitalization? Well, as of today, if you just look, we have 75 percent of the over 60 year olds who are fully vaccinated. Three quarters, a quarter not. If you take the measure , you can say 200 is the new 50. Four times that. If you just deduce it from the stresses that can arise and would stand at a 50s incidence for the health care system. We have to and we will continue to discuss this with the federal states, with the Robert Koch Institute and with others in the modeling. This interplay of the indicators, so to speak. But we see in the United Kingdom that even with a very, very high number of people vaccinated, if nothing else applies, at least in this phase of the pandemic it is not without consequences. “
