Yeah we live in a globalized world, corporations are global entities and companies from other countries made meaningful contribution. They still were predominately developed, tested, manufactured and distributed by US companies... thats why BioNTech had less than a billion of revenue last year to Pfizer's 7.5B Operating Income. You wouldn't have it at this scale without the so-called 'trash' US healthcare system.
Johnson and Johnson was developed by Janssen which is based in the Netherlands and Belgium [1].
And as others have pointed out, Pfizer was developed by BioNTech in Germany [2].
