i was going to make a guess at why black people have lower rates, and this graph pretty much confirms my guess.
I grew up in DC in the eighties, havent been back in decades now but when i remember most of the black people i met the overall common characteristic is that they were poor. Well, being poor correlates with less eduaction, lower life expectancy/younger population, and importantly having less free time. Where i live we have fewer and smaller minority groups, but we have a lot of poor people, and the same things happen.
another thing about being poor is that you avoid the doctor at all cost, most dont ever go- just going to get bad news and bills you cant pay. I recently saw a clip of a guy running off a stretcher to avoid paying an ambulance in the US, the cost of health care is absurd and many people avoid treatment because they cant afford it. also, "muh tuskegee" aside, there is a do ented history of racism in medicine, I guarantee you minorities always prefer doctors from their minority and that makes access more limited too.
i suspect latinos do better here because culturally we are more socialist and expect the government to give health care, and because vaccines greatly improved life expectancy in the region there is less skepticism. though they exist too, including the educated loons
gov here just announced a third dose for older people (sinovac). Giving one dose of pfizer as a third booster for inmunosuppressed. covid is similar to flu, makes sense that boosters will be needed. vaccine rollout here was very good, but young people held out, the gov made rules requiring a vaccine passport and they straight up put a curfew at 10, and for it to go to 12 the region has to be at 80% vaccination (both doses). a lot of the holdouts got their shots, cases are now way down but still havent hit 80% in my region- americans love their freedom, you would go crazy even though most of you are already home in bed at 10
covid is tricky, its very contagious and affects people very differently, some are asymptomatic while others go down in days. I got it a week after getting my first dose of vaccine, from work, and my family- it ended up being a light cold for us, and a rough one for my unvaxxed coworker. the vaccines job is to prevent hospitals collapsing and hopefully reduce transmission, but for it to really work you need 90% of the population to vaccinate.
