Yes. As I said, it's not true that no research is being done; these populations will continue to be monitored for the rest of their lives as part of epidemiological studies. It's just that you don't report epidemiological studies every year. You come back every five or ten years, or perhaps at an even longer interval than that, to report the study, particularly if nothing has been found.
