Headlines always get me. Correlation identified, but not causation.

As a practical matter, studies about links between major diseases will always always be talking about correlation.

To reach 'causation' would require intentionally giving your experimental subjects Covid-19 (and in a way that didn't result in them knowing they'd had it!), and that's unlikely to pass muster with the ethics review board.
