The linked article doesn't support either view.

The link reports that vaccines have been observed to generate higher antibody-levels than natural infections. It was also observed that vaccines seem to protect against a set of variants. This is the good news that is worth reporting.

But there are observed occurences of the opposite; that vaccinated people test negative for antibodies. Similarly, people test negative for antibodies some time after recovering. Sometimes, recovered people never test positive for antibodies.

Diagnostic tools widely available are simply not good enough to test the immune response.
