The spike protein has a cleavage site which reacts with furin-related enzymes on the cell to increase infectivity 1,000-fold compared to the ACE receptor interaction...do these peptides interfere with that?

Secondly, will this compound need to be taken prophylactically forever?
What I’m thinking, is if the compound interferes with the virus binding to cells, will the body develop enough of an immune response, to maintain immunity? Compare the common cold (also a coronavirus) which keeps circling around year after year.

(also a coronavirus)

Mostly rhinovirus, only about 1/5 coronavirus.
