That's not true. The pandemic ended as Omicron became the dominant strain, which was by some measures 90% less fatal than Delta.
It's selective breeding; because we became careful about recognizing symptoms, any severe strain would cause the infected to isolate and hence not infect others. Therefore, Omicron was often symptomless, and COVID-19 was no longer deemed as much of a threat.
