I realise that this is a long shot and I apologize in advance if I am wasting the time of any professionals working on COVID-19.
I was surprised to learn recently that people that have recovered from the coronavirus may still be producing virus particles although these may have been deactivated as a consequent of the attachment of antibodies.
It seems to me that there might be a survival advantage to the evolution of a response to the presence of such deactivated particles.
Has there been any research to see if people who are exposed to those that have recovered from a coronavirus develop an immune response?
immunity contagious are the words don't go together.
Immunologic reactions and exacerbation of pathogenesis. It can happen when one get infection.
A couple of companies have started with phase I trial. The results will show as how real immunity is developed in uninfected subjects!!

Immunity to current Coronavirus pandemic (COVID-19) can be active (after infection or an effective vaccination) or passive (by use of serum from a person who has recovered.
Immunity and contagious are two different terms:
Immunity is the ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.
Contagious (for an infective disease) is the spread from one person or organism to another, typically by direct contact.

I think it's a clever idea. Our species should evolve a pathway for this at some point in the next 100 million years.
Dear Christopher James Davia, immunity makes a body able to resist a particular infection by the action of specific antibodies that are produced against that particular infecting agent. There is no natural route of transmission of one's antibody to others. So, I think contagious immunity is an erroneous term.
More questions than answers about immunity after recovery from COVID-19.
