It's a dead virus. It can actually cause flu. Why do people feel sort of crummy afterward? It's because the flu vaccine is actually working. Making your immune system fire up, get ready and recognize it actually sees the flu how to kill it. No, it's not. 100% fail safe, but it's still gonna offer a lot of protection. So you're not gonna be as sick as likely to get sick. Or if you do get sick, have a shorter duration. Okay. So if you're like me, uh, your mom probably said Don't go outside in the cold. Got your hat on. You're gonna catch the flu. You can't catch the flu from just simply being outside in the cold. But it does raise the question. Why are there so many more flu cases in the winter months? You're likely to stay indoors more so if one person is sick, more people are likely to get sick. The sun is lower in the sky, and as a result, you have less vitamin D actually being produced in your body. Your immune system starts to get suppressed a little bit. You're more likely to get sick with the flu. The winter months tend to be lower humidity viruses like the flu virus. They like lower humidity. They're likely to live longer. So your mom may have been right. I mean, look, moms are always right, but maybe not for the reasons you originally thought.
