when did we discover immortality? and why was I not told about it? For instance since the dawn of time people have been dying from cancer, yes we have developed some treatments but people still continue dying from cancer in large numbers. Sometimes we get lucky and we find a treatment that is 100% effective, other times we don't and people still continue dying.

You find tailoring a vaccine in such a short time that helps astonishing but you expect to magically find a cure that makes everyone that catches it better in no time.
