In fact, they were explicitly directed to not consider other countries while evaluation the question. To the point that they were told they would effectively be stopped and their mic turned off if they directed the discussion to include vaccinating other countries instead of just looking at the question being discussed about general approval for everyone for a third shot of Pfizer.
People forget about the open comment period, but it's part of the process, just like at a school board meeting. And, just like at a school board meeting, anyone can sign up and get their 3 minutes to say just about whatever they want to say. Even if they show up and just spout conspiracy theories for their entire 3 minutes, they'll get to speak for that time. It's kind of wild.
Now, what was truly wild and novel, was the second question. The meeting discussed all the options, and then they voted on the question at hand, "general full approval of a third dose for everyone". Not just EUA, but the full deal general approval. That's why it got the "no" vote, it was too big, not enough data, and not clearly "better" for that population. Then came the wild part. They took a 15 minute recess and the FDA sort of said "hang out and we're going to go write a brand new question on the fly and have you vote on that one too". That's where the question about high risk people and occupations came from, and I think only for EUA too. Meaning the second vote was a recommendation to approve an EUA for a third dose of Pfizer to high risk people or people in high risk environments. That passed easily. Being both EUA, not full, and targeted at higher risk meant that a lot less data was needed for the risk/reward math.
It'll be interesting to see what the FDA decides to do with the two recommendation votes and what the CDC decides in it's own meetings too. It's probably a super safe bet that they follow the second question. The first, they could follow too or they could decide to just ignore it, but I doubt it at least for now until there's more data.
