Slightly off topic, but it is quite interesting that US media very consistently uses "Pfizer" if the news is good and some variant of "Pfizer/Biontec" if the news is bad. The opposite holds of course for the German press, which addresses the vaccine as "Biontec" when the news is good.
"I’d just like to interject for a moment. What you’re refering to as Pfizer vaccine, is in fact, the BioNTech-Pfizer vaccine, or as I’ve recently taken to calling it, BioNTech plus Pfizer vaccine. Pfizer did not develop the vaccine by itself, but rather another company called BioNTech created the original formula, which went through Pfizer's clinical trials and became the vaccine we use these days.
Many people who got the vaccine refer to it as the Pfizer vaccine, without realizing it. Through a peculiar turn of events, the BioNTech-Pfizer vaccine which is widely used today is often called "Pfizer", and many of its users are not aware that it is basically the vaccine initially developed by BioNTech.
There really is a Pfizer contribute to the vaccine, and these people should partly thank that corporation, but it is just a part of what allowed them to be vaccinated. Pfizer is the distributor and responsible for clinical trials. Clinical trials are an essential part of a vaccine, but useless by itself; they can only be done once somebody developed the vaccine in the first place. So, the Pfizer vaccine can only be used because it was developed in the first place by BioNTech: the whole system is basically BioNTech with Pfizer contributions, or BioNTech/Pfizer. The so-called Pfizer vaccine should really be called BioNTech/Pfizer!"
