Nowhere in your linked article indicates that "no existing facilities were added".
> As of January 2022, the Pfizer-BioNTech COVID-19 vaccine is manufactured between 11 sites across five countries, including the U.S., Germany, Belgium, Ireland, and Croatia, and engages more than 20 suppliers.
I'm from Belgium and i did follow up on Puurs and i hadn't encountered any news that they needed to upgrade facilities there.
That's what you should have copied my whole sentence: "as far as I'm aware, no existing facilities were added". Which in retrospect should be upgraded actually. Didn't notice that mistake.
