Excellent explanation of the numbers. Thank you. The question that I seem to run into annually centers around my "risk factors" weighed out versus the downside of contracting the flu versus the risk of putting an additional lab-made concoction into my body. What I mean is...I don't spend my days around many other people. Other than going to the gym daily, I may only see my family plus one or two others. Mathematically my factors there are low. Now I have two kids and a wife who works in the schools, so they definitely bring things home. That increases my risk factor. I'm healthy and not in any way immunocompromised and getting the flu definitely sucks, but it's not going to kill me. So the third piece, and I realize this may not be "rational"(I really do) is that if I'm not around a lot of people and I'm healthy, then why am I going to put something that was made in a lab (under comparatively "rushed" versus typical FDA drug approval guidelines) into my body? And I'm not making a statement here. I really am asking. Every time I think about it, given this particular set of circumstances, I opt against it. But maybe I'm just being paranoid or foolish. I've been wrong in the past. (Once. Maybe.) For people who are elderly or sickly or work in a hospital or, etc., etc., etc. I absolutely see the logic in it. For me, I just never have. But I'm open to hearing how dumb I am.
