I was given the choice, since I work at a bunch of hospitals.
This is in the name of splitting hairs. I would have been thrilled to get the Moderna vaccine as well but I chose Pfizer for a few reasons.
1. Pfizer has a lot more to lose if something goes wrong with the vaccine. Moderna has never brought a product to market before, has never mass produced a product, etc. I trust companies to do what's in their interest and that's why I have some level of trust in Pfizer.
2. The Pfizer vaccine has been around and tested for 1-2 weeks longer. Almost nothing but not quite nothing.
3. Given the similar nature of the two vaccines, I would bet they require the same temperature to store, but that Moderna's testing was closer to the threshold of instability. So, I think Pfizer has a better chance of being stable since it's required to be stored in a freezer.
4. But MOST IMPORTANTLY, I was offered Pfizer about 1 week sooner and it was convenient, didn't have to schedule, I just walked over to the tent after my last procedure.
One the flip side, Moderna has NIH funding and all the required monitoring and reporting that goes with that. Tony Fauci AND Alex Azar got Moderna and between the two of them, you have safety, efficacy, and quality control folks putting their money where their mouth is.
I'm not sure which is better. Both about 95% effective after series completion from what I've seen. I took first offered which was Pfizer on 12/16 (and 2nd on 1/2). I wouldn't make too much of Fauci picking Moderna. Their vaccine was created in partnership with National Institute of Allergy and Infectious Diseases of which Fauci is Director. So naturally, Fauci is going to be heavily biased towards Moderna since that's his dog in this fight. That doesn't make it any better or worse, just that Fauci is going to back it no matter what.
