With vaccination the risk of PASC (long covid) decreases. It is a commonly held belief that viruses become less deadly over time, but that is not supported by the science. The truth is far more complex. Approx. 2300 people die from covid each week in the US. I can't quote numbers for other countries. I can highly recommend TWIV (This Week in Virology, https://www.microbe.tv/twiv/), and related podcasts (https://www.microbe.tv/science-shows-by-scientists/), if you want to keep up to speed on the current science in infectious disease.
