IF HCQ is used for prophylaxis before you are infected, you will not develope an immunity
the HCQ prevents the virus from replicating and causing an 'illness'
IF you are taking HCQ prior to infection you get infected so mildly that the immune system doesn't develop a response
"My concern about the drug in the pre-infection state or the infected state is that they block the innate immune pathways that may allow the immune system to detect virus and to start a response against it," says Art Krieg, who has spent decades studying this process. He sees both drugs as likely to be more useful to treat late stages of the disease, as has been done in China and elsewhere.

it just stands to reason
IF the HCQ works the way we think it does then using it to prevent the illness only delays things
using it to cure the infection does leave the patient with immunity because the immune system is activated by the 'infection'
but if the 'infection' never rises to the level needed to produce the immune system response…
>Plus letting vulnerable people take CHQ when there is community spread could be.done.
I agree
while taking it their bodies will react as if never exposed to the virus
the HCQ prevents the viral replication necessary
> you won't develop antibodies,
better to catch it, and then take HCQ early in the progression of the illness
