Nobody freaks out about the flu because it's nowhere near as contagious or as deadly as CV. But you still reschedule the brunch with your 95 year old grandparents when you're sick with the flu, right?

The reason the flu vaccine doesn't always work is because the virus mutates so fast.

You can't just build immunity to some new virus by being outside in the dirt. Your body had to encounter the virus and develop antibodies for it. The reason a vaccine is great is because the virus is dead, so you don't have to risk permanent lung damage that might occur from a corona virus infection. Your immune system simply sees the dead virus and makes antibodies that will fight off the live virus if you ever encounter it.
