I could agree with the sentiment behind this if the vaccinations had been made mandatory. I'm guessing there were a few people who didn't quite understand the risk they were taking, but that's probably a very small minority.
My feeling on this is, hey somebody had to take point. I know it sounds cold, but to me it just makes sense that people at the end of their lives should go first, and since the vaccinations were voluntary I'm guessing a lot of the people we're talking about saw it the same way.
Myself, I'm just over 60, and I signed up for clinical trials for one of the lesser known (and most likely least tested) vaccines before there was any real certainty about their safety because, I figured: I'm 60+, I don't have any kids, I don't owe anybody any money
, I've never had to fight a war, live through a major economic depression, an ice age, invasion by space aliens, or a zombie apocalypse (although I have to admit I'm kind of disappointed about that last one).
Relative to almost anyone you want to point too through out all of human history I've had a pretty cushy life so far.
If I can do something to make the world a little more certain and safer for the rest of my species, I kind of feel like I have a responsibility to do so even if there's a little bit of risk.
That said I haven't been called up for the trials yet.
