Not sure I have this right (or that the article did), but it seems the initial vacs failed. When the Pfizer vac was added as a “booster”, the result was substantial immunity. The conclusion being pushed is that magic synergy from the combination was the key.
Simpler explanation: the Pfizer vac produced the immunity, and would have in the absence of the others. Did I miss where the article disproved this?

FWIW, PFizer is the only ‘vaccine’ used in Israel and their current hospitalizations for Covid are half or more patients who are fully vaccinated.
