Indonesia is a developing nation, with most people still laboring as rice farmers and making $1 - $2 per day.
I'm sure they're deficient with any vitamin not found in rice, which they eat 3 times per day. (Rice is packed with calories, not vitamins.)
Also, due to corona, there is starvation in the cities. In the West, we use automation to ship groceries, but in Indonesia they unload trucks using manual labor. So the lockdown means they can't unload food trucks, or it gets delayed.
Additionally, many people have no income, or 50% of their former low office salary, and Indonesia is not a welfare state, so people cannot afford food at this time. Very tragic example of lower-income group receiving the worst treatment during this pandemic, basically famine.
It's totally unrealistic to expect them to hang on until 2022.
