truth has become subjective, as you say. That's purposeful. When you see easy solutions to difficult problems you can be fairly certain that is not the truth. There's a great deal of that, these days. It's called populism. And it's a cancer. I try to read international news as well as national news on both sides, keeping in mind motivation. Most often it's money. Re covid, science is not static. It's dynamic and that must be kept in mind at all times. The question then becomes "are those providing the science truly after knowledge or something else". It's usually not difficult to discern.
