Let's be clear about "natural immunity." I know it is often uses as a shorthand for "getting infected with a virus and surviving due to the body's immunological system."I would think natural immunity and vaccinations are the only way out. I’m not entirely sure it ends any other way, certainly doesn’t look like vaccinations only will do it. (Got my vaccination debating the booster currently.)
But that natural immune response of the body is also the very same natural immune response from a vaccine. A vaccine causes a "natural" immune response.
Yes, the vaccine isn't "natural." But neither are most medications or surgeries. Getting monoclonal antibody infusions or anti-viral medications ain't natural either. In the end, the body needs to respond "naturally" to get better.
And it's a heck of a lot better to create that natural immune response from a vaccine, which has a minuscule risk, than having a virus replicating in your body, destroying cells and organs, and giving one good odds of being hospitalized or dying.
And the "natural immune response" from catching the virus can wane over time, just it can from the vaccine. The only way to boost the immune system "the natural way" from getting infected *again* is to risk serious illness or death over and over again. With the vaccine, that is accomplished with a booster shot and avoiding possible death.
And so... the plan to rely on both vaccinations and actually getting infected is a bad idea compared to everyone getting vaccinated. Because then you avoid all the stays in ICU and the pile up of dead human beings.
