Fear not, antibodies are fit to tackle COVID variants

Associate Professor Kim Good-Jacobson

The Atlantic ran a feature story about the body’s defence against coronavirus variants in which Monash BDI’s Associate Professor Kim Good-Jacobson appeared. The gist of the story was that the virus was evolving but the antibodies that fight it can change, too. The immune system is not doomed to be discombobulated by a never-ending barrage of shape-shifting variants, the article said. For every trick the virus plays, the immune system arguably has an equally impressive one. Associate Professor Good-Jacobson, one of several scientists from around the world in the article, explained in detail how B cells, part of the adaptive immune system, collectively “respond to any foreign pathogens they see” and how they evolve to defend against variants.
