Your Immune System Evolves to Fight Coronavirus Variants (Scientific American)

A lot of worry has been triggered by discoveries that variants of the pandemic-causing coronavirus can be more infectious than the original. But now scientists are starting to find some signs of hope on the human side of this microbe-host interaction. By studying the blood of COVID survivors and people who have been vaccinated, immunologists are learning that some of our immune system cells—which remember past infections and react to them—might have their own abilities to change, countering mutations in the virus. What this means, scientists think, is that the immune system might have evolved its own way of dealing with variants.
