Good question, but the problem is that just running into it might not be the right way (if there is a right way). Yes, you can dive right into the cold water, but there might be sharks down there. We really don't know enough about sharks yet.
And we don't know how long any potential immunity to COVID is conferred by catching it, or how general that immunity it. I personally know a couple of people who had it twice almost certianly, and we're a highly vaccinated group around here. They aren't certain because the first time, we were still in detect-by-symptoms unless you're in the hospital mode (March 2020). The symptoms were what are commonly described -- loss of smell and taste, severe cold/flu-like symptoms, and both parties work in public-facing jobs, for for a veterans' club, and the other for the local food bank. The second time, about 8-9 months later, it was tested and confirmed, and much more serious. This is anecdotal, but there isn't enough data on the real world population to know how strong, long-lasting, or universal the natural immunity is.
So until there's a chance for either science to figure it out, or other people to go ahead and jump into the possibly shark-infested cold water, and find out the (possibly) hard way.
