One person told me that the mRNA vaccines induce 60x the antibodies of a recovered Covid patient (closest source I found), such that even if your response was weaker, it should still be more than powerful to deal with any actual Covid.
Antibody count is not the only thing that matters. Antibody diversity also matters. A recovered Covid patient has antibodies against multiple Covid proteins while a mRNA vaccinated person only has antibodies against the spike protein.
That means that if you are exposed to a variant with mutated spike protein you are better of as a recovered Covid patient because you still have antibodies against other proteins.
