    Yes, Covid-19 is still considered novel, but saying that we are dependent on evolutionary-scale changes to develop immunity is just wrong. The immune system learns to recognise infections relatively quickly, which is literally why vaccines work. It’s also why people typically only get infected by seasonal epidemics once in a season, because we quickly build a short-lasting “immunity” to the virus that is in season.
