So what's the conspiracy theory?
the conspiracy theory:
the other options will still be allowed;
this gives Pfizer both the ability to legally mandated (in theory - still needs to see a court), and also distribute experimental drugs at the same time.
it's basically just a bunch of regulatory smoke and mirrors.
follow the money.
They did a full approval for Pfizer for 16+ and an extension of EUA for practically everything else in the same document. They aren't letting go of this one. They want more normalization. I think Pfizer has the most reports of negative side effects on social media, so this might help them push the other "options".
