India's death rate has been much lower than the US. Part of this is because they're already doing widespread cholecalciferol roll-out.
If cholecalciferol is not on 2021's CDCs/FDA/AMA number one recommendation list for pre-Covid control, I will have considered the AMA a complete and utter failure in the united states.

Average age in the US is 38.
This probably accounts for the difference in death rate.
> We didn’t understand early on what a major risk factor obesity was. … It’s not until more recently that we’ve realized the devastating impact of obesity, particularly in younger people,” says Anne Dixon, a physician-scientist who studies obesity and lung disease at the University of Vermont. That “may be one reason for the devastating impact of COVID-19 in the United States, where 40% of adults are obese.”
First of all it seems unlikely people in India don't get enough vitamin D, it is a lot further to the south and inside the area that should have enough sun year round.
I don't think you can compare death rates in India and USA, the healthcare and accountability is just way different. Even though it is not great for the poorest ~50% in USA, it is really not good for the poorest ~90% in India. Those numbers are made up, but meant to illustrate that real healthcare in India is mostly for the wealthy.
