I'm not sure I'm looking at the same data as you are, but as far as I can see, approximately 17,000 died from Hiv in 2019 in Thailand.
If that is the correct number it's still more than I thought. It's close to 8 % of the total deaths in Thailand if my calculator works. Almost at par with road deaths, which is kinda spooky.
As far as deaths overall from covid 19 it seems like after the delta variant arrived, that the ones now hospitalized are getting younger and younger and that most of them are non vaccinated or only had their first shot.
That's the case here in Denmark, where more than 90% over age 50 has been vaccinated, so even if people are in a bad shape and elderly , it seems like vaccinations are doing their job and keeping many of them out of hospitals.
Off course vaccinations can't save all, but they can minimize the risk a lot.
