Of course, and this does not do that. It neither primes your immune system to fight off catching the disease in its earliest of stages, as in you may catch the virus, but before you have a chance to feel unwell, or show symptoms, your immune system has already dispatched the invader without you even knowing it., therefore you don’t pass it to others. This is how traditional vaccines work. With this (whatever it is) you do catch it, and you do feel unwell and have symptoms, and you can pass it to others. @OldBrit
