We usually hear about it first from someone else. One of the kids at daycare falls victim to it. Your co-worker comes down with it. You hear about the first few cases of it on the news.
We’ll do everything we can to avoid it. The dreaded, the awful, the debilitating...influenza.
Viruses are funny things. Deadly things. We can get the flu shot, which may offer some protection. We can wash our hands, and avoid touching our face. But hands-down our best line of defense against influenza is our own immune system.
Our immune system is designed to protect our cells from viral replication. Even if we are exposed to a virus, our immune proteins are devised to target the intruder and stop it from invading and multiplying.
