But first you would need to get infected to acquire such immunity. Pretty much defeats the purpose when it could cause severe outcomes which you wanted to avoid in the first place. But rather, even though you may get the infected after vaccination, it will lower the chance of severe outcome by nearly as much. I’d rather acquire natural immunity via the vaccine route.
