Getting Hooked on Boosters

So they came up with a vaccine that has prevented many people from contracting Covid. At least the declining death statistics suggest that. But the vaccine isn't so great that you can just get one, like some other vaccines. No, you need two of them a few weeks apart for it to work.

Okay, fine, I'm down with that, I guess, even though I'm not quite sure why they just can't give you one dose that's strong enough, like the ones for tetanus and diphtheria and shingles and smallpox and some others.

But now it turns out that actually even two shots don't do the trick, and so we now need a third shot, euphemistically called a "booster." But wait a minute -- wasn't that second shot the booster? Here's the definition: "An additional dose of an immunizing agent, such as a vaccine or toxoid, given at a time after the initial dose to sustain the immune response elicited by the previous dose of the same agent."

So now our booster needs a booster! What if our booster's booster needs a booster? Maybe they should go back to the drawing board and work on finding a vaccine that actually works right out of the gate, just to mix a few metaphors.
