it isn't apples to apples. Some studies show that SA has >70% seroprevalence [1], most of which from infection. If it holds that recovered immunity confers __better__ protection than naive vaccine immunity [2], then that 30% decrease might as well be from the protection conferred mostly by the former, and we have no idea how that would translate to vaccine naives, who are the majority in highly vaccinated developed countries.
