My daughter is still working on multiple potential vaccine programs and we've talked about the wide variation in how this hits individuals. Roughly 40% are asymptomatic and either never know they had it or just felt off for a day or two. Another 40% (making 80% of the total) have only minor effects and so the common refrain from 4 out of 5 people who get it is "nothing to worry about." Setting aside the couple of percent fatal who are usually vulnerable due to age, blood pressure, etc, almost 1 out of 5 DOES have serious symptoms and about half of those (close to one in 8 people) have long term damage.
I'm not worried about dying; when it's my time so be it. But I have no desire to be in that one out of eight or even the one in four. Plus, we've got a 13 week and 88 year old in the immediate family bubble.
On a somewhat related note, the reason the FDA had resisted the political pressure about approving convalescent plasma is that (1) the real results have been marginal, (2) efficacy depends largely on the amount of antibodies the donor had, (3) making the results highly variable for any particular patient. Using convalescent plasma has been around for close to 100 years and almost 100,000 COVID patients have already had it, so the therapy is hardly new or ground-breaking, but it made for good politics going into a political convention.
