Knowing that the normal entry points of the virus to the body are the nose, mouth and eye:
would it be possible to purposely administer the virus to someone so that it will only result in mild symptoms? Maybe even infecting other areas inside the body (by let's say injection) where it cannot spread too much. It can be useful in situations where the probability of catching the virus in the long run is very high. For example one may prefer to infect the eye and protect the other entry points if possible.
In the same line of thought, maybe infect and then being knowledgeable about the infection one can start the treatment even before the first symptoms or at the first symptoms and aim for later immunity.
The general strategy involves trying to choose the entry point, "inventing" a new entry point and/or choosing the moment of infection to have the optimal conditions for the treatment applied to covid-19. This cannot be worse for someone compared with becoming infected "naturally" and it can make sense when there is a state of big urgency and no time for a vaccine.
