A number of important and scientifically proven measures to reduce corona infection and mortality have not yet been sufficiently publicised. For example, FFP2 masks should be issued not only to the 24 million people at risk, but to ALL Germans.
FFP2 masks should be worn wherever people come closer than 3 metres apart - in shopping streets and city centres especially, and indoors, i.e. in schools and at work, unless you are sitting in a ventilated single office. The introduction of everyday masks has reduced the transmission rate in Germany by 47% according to a recent paper, but FFP2 masks can reduce the transmission rate by 85%:

Wearing glasses can reduce the risk of infection by an additional 78%.
According to a study by the University Clinic of Hamburg, 84% of Hamburg residents have a vitamin D deficiency - and this increases the mortality rate from corona by 55%. According to studies, taking vitamin D beforehand can reduce mortality by 92% in corona patients in hospital. Therefore, the federal government should ask every German to take 20,000 IU of vitamin D a week or 3,000 IU a day.

In Corona patients who took aspirin before admission to hospital, mortality was reduced by 47%. The recommendation should therefore be to take 500 mg ASA once a day for flu-like infections or covid-19 instead of the most commonly taken paracetamol or ibuprofen.

Given the unprecedented fundamental rights restrictions and the massive physical, psychological, social and financial collateral damage of the lockdown strategy, I think it is overdue to publicize these simple measures as well.
