Scared That Covid-19 Immunity Won’t Last? Don’t Be

edited July 31 in The OT Bullpen
This article provides easy to read background information. Here are a few excerpts:
Dropping antibody counts aren’t a sign that our immune system is failing against the coronavirus, nor an omen that we can’t develop a viable vaccine.

The adaptive immune system consists of two types of white blood cells, called T and B cells, that detect molecular details specific to the virus and, based on that, mount a targeted response to it.

That antibodies decrease once an infection recedes isn’t a sign that they are failing: It’s a normal step in the usual course of an immune response.

Nor does a waning antibody count mean waning immunity: The memory B cells that first produced those antibodies are still around, and standing ready to churn out new batches of antibodies on demand.

And that is why we should be hopeful about the prospects of a vaccine for Covid-19.
