Your perfect immune system, right. Maybe you’re young now and don’t get sick much. Maybe you never leave your house and that’s why you’ve had two colds in 5 years. You’re being a dick if you’re walking around being a carrier and other people have weak immune systems. My coworker has an immune system disease and she hasn’t done anything social in 3 years because the vaccine doesn’t work as well in a damaged system. So GLAD that you’re ok. For other people they don’t have the luxury to ignore COVID. As a personal note, I’m healthy too and get a cold here and there because I work with little kids. I’d get my flu shot sporadically before. Some years I did. Some years I didn’t. Before COVID I caught a massive bout of flu that left me in bed sweating, with a fever and a splitting headache for 5 days. My immediate family had their flu shots and didn’t get sick in the least. I learned from that lesson. I’d rather have a mild reaction and feel a bit off for a day or two after a shot than to have to endure that again.
