Aimee Bernard discussed the responses to a virus versus to a vaccine at the Unbiased Science Substack. She wrote, "
Calling infection “natural” implies it’s somehow better or safer. In reality, infections that happen out in the wild (think schools, grocery stores, and soccer games) are uncontrolled, unpredictable, and often dangerous. And calling vaccines “artificial” makes them sound synthetic or foreign, when in fact they work by engaging the same cells and components of the immune system that infections do. So, let’s reframe the conversation: it’s not “natural vs. artificial,” it’s out in the wild exposure vs. guided immunity...So, the next time someone talks about “natural immunity,” ask them: Would you rather train your immune system with practice from a vaccine — or throw it into a real fight and hope for the best?"
