On Immunity: An Inoculation

by Eula Biss

The very expression herd immunity suggests that we are cattle, waiting, perhaps, to be sent to slaughter. And it invites an unfortunate association with the term herd mentality, a stampede toward stupidity. The herd, we assume, is foolish. Those of us who eschew the herd mentality tend to prefer a frontier mentality in which we imagine our bodies as isolated homesteads that we tend either well or badly. The health of the homestead next to ours does not affect us, this thinking suggests, so long as ours is well tended.

If we were to exchange the metaphor of the herd for a hive, perhaps the concept of shared immunity might be more appealing. Honeybees are matriarchal, environmental do-gooders who also happen to be entirely interdependent. The health of any individual bee, as we know from the recent epidemic of colony collapse, depends on the health of the hive. In The Wisdom of Crowds, journalist James Surowiecki details the sophisticated scouting and reporting methods honeybees use to gather nectar. The cooperative work of bees, Surowiecki suggests, is an example of the kind of collective problem solving our own society depends on.
