It does provide immunity by allowing your immune system to learn to fight SARS-COV2. The reason why they want recipients to still wear masks for now is because of the characteristic of the virus to shed and be infectious to others even before you develop symptoms. For all viruses, even those with vaccines, you’ll get some virus cells in your body before your immune system kills it. So there’s a little window where you could be shedding virus even though you haven’t really come down with COVID. That’s just the nature of the virus.
