Technology-wise, the vaccine you mean was developed in Germany by a German company. Pfizer is the manufacturing partner and did logistics for clinical trials (except in China, where Fosun licensed it).

$445 million in funding came as a grant from the German government, the rest from licensors. The German government has split another ~300 million or so on two other companies also working on vaccines. The US government did not contribute any funding to Pfizer's license.

I'd rather say it's a cool example of international collab and winning together than an American exceptionalism narrative ...
