50 years from now they're going to look back and marvel at the scientific achievement it was to create a vaccine so quickly that made such an obscene impact almost immediately. And they're also going to look back at how dumb a significant slice of the population was. An unvax'd family member just died from covid. She was young and healthy, which only meant that her ICU suffering was drawn out even longer and she survived things (multiple PE's, septic shock, fungemia) that many sicker people die from immediately. But the end result was the same.
I got my vaccine series kind of late. Well my second shot at least, just due to laziness and being busy. I got the pfizer series but will likely get the moderna booster depending on what the data looks like 5ish months down the line.
