Its important to keep studies like this in mind when talking with people who refuse to take the vaccine because they "already had COVID". In a very real sense, if natural antibodies are durable, persistent, and effective; the vaccine is an unnecessary medical procedure. Doctors would not cut off your legs for no reason; that would be unethical. The vaccine is a medical procedure like any other; if the benefit is questionable, it would be unethical for doctors to administer it.
Yet, we have an increasing number of venues, workplaces, and events which are requiring proof of vaccination to participate. This is forcing both people who already have antibodies, and even people who can't make antibodies (e.g. immunocompromised, solid organ transplant, etc), to undergo a medical procedure for little to no benefit.
