> Governments could have used the last two years to execute on policies to reduce these chronic diseases: better food, better air quality, better water quality, a less stressful lifestyle. Governments have been working on these problems for decades already. Food/obesity is only getting worse in rich countries, air quality and water quality have seen marked improvements over the last half-century from lead reduction, decommissioning coal plants, emissions regulations for cars etc. However expecting government to dramatically reduce the number of overweight people suffering from diabetes in just 2 years without extreme authoritarian measures (e.g. concentration camp where they monitor your food intake) is pretty much just fantasy. Many different methods have been tried all over the world like education, food labeling, soda taxes, etc. and people continue to be fat when they can access and freely buy modern foods. The nice thing about a vaccine is that it’s far easier and cheaper to use and deploy than any of these other improvements. A vaccine costs $1 to $100 per person, while transitioning the entire economy to solar, wind, and nuclear power within a few years to improve air quality would cost what, $10,000s per person? If even possible at all.
