I wonder how many people who died of malaria would still be alive today had DDT never been banned.

Tough to say. Not all countries have total bans on DDT, and even the Stockholm Convention exempted vector control from the ban on certain organochlorine compounds. In any case, DDT-resistant mosquitoes were already starting to occur in the 1960s due to the unrestricted spraying. Spraying has mostly continued as indoor residual spraying, which still seems to be quite effective.

In the West nobody dies from malaria because we have a healthcare system. So DDT is unnecessary.

Africa is another matter entirely. For centuries no white man made it further than the beach until an effective medicine was invented.
