Ventilation through HEPA air purifiers and validate them with CO2 monitors, free or subsidised testing, routine testing of sewage water to determine hotspots, increased surveillance of new variants (not winding down the programme), educating the public on the benefits of high quality FFP2+ masks and provided everyone a number of free government approved ones, dropping the patents on vaccines and sharing technology and expertise to enable poorer countries with very low vaccination rates to greatly boost this which reduces the opportunity for new variants to emerge. Fund the development of better vaccines and treatments (make the treatments more widely available) and extend the booster programme to anyone who wants one. Is that enough?
