Avoid being sick with two things at once or being sick with something else immediately before.
When it comes to supplements the evidence and effect sizes are not that strong. Referencing examine.com and what I generally remember, I roughly think that the best immune system strengthening supplements would be zinc and echinacea with maybe mild effects from other things like vitamin C, vitamin D, and whey protein. There may be a couple additional herbs that could do something but it’s unclear they are safe to take for a long duration. What you’d aim for is decreasing the severity of viral pnemonia induced by something like influenza.
It’s possible that some existing antivirals will be helpful but currently this is unknown.
Nice list!
