I don't have the data. Last year in the summer when I asked them about the vaccine, they were in the unsure category and that helped shape my opinion on the matter too. Since then they have enough science behind it to trust the vaccine. This winter break when I saw them, they explained why they took it so fast and encouraged I do the same. I trust them and will do it.
I'm in California, probably the worst state for the vaccine rollout. My gut feeling is by the time it gets to me I may not have 6 months data, but probably will have at least 3 months worth. Regardless, if people aren't dropping dead or growing an extra arm within a month or two then chances are extremely high they have outlived any negative effect (otherwise it would have reared its head by then). At least, that's my justification for taking it.
