It's discussed here:Can you really compare 50 micrograms of Pfizer to 50 micrograms of Moderna?
I had assumed that the formulation was different for each. Or are they exactly the same except for the dosing protocol? Or maybe close enough to the same to compare?
A decision to go with a lower dose might have helped speed things up last year. Now we may be seeing the consequences.
I feel like someone has posted this article before, so apologies if I'm repeating existing information. This is a looooong thread
