Somehow I missed this 2024 Reuters report on how the first Trump administration ordered the US military to carry out a psyop campaign that spread disinformation about COVID-19 around the world.
In particular, the campaign falsely claimed that the Chinese vaccine ChinaVac is unsafe/haram or ineffective. It also doubted the usefulness of face masks. As a result, lots of people died.
