It might be the right approach but that’s not at all “obvious,” and the question has philosophical, ethical, and political roots. Do we immunize the most vulnerable to make sure they’re taken care of or do we immunize the most likely spreaders to reduce the risk to everyone, including the most vulnerable, relatively equally? How do you weigh in existing precautions, ongoing changes to those precautions, financial struggles, and employment demands to these decisions? Do we focus on regions currently most affected or do we roll it out equally? There are a million questions like these and the choices aren’t all obvious.

Your post is unnecessarily hostile, ignorant, and insensitive. I knew someone who died of the disease. He was half my age and I’m too young to be eligible for the vaccine. Not all young people “brush it off.”
