Vaccines normally take 3-5 years for other reasons.

This vaccine took 9 months to get through clinical trials to approvals.
Yes, that's fast, but not crazy when you consider:
1) They had lots of test subjects. Recruiting 1000s of volunteers for phase 1, 2 and 3 clinical trials was easy and quick, compared to most vaccines which take a long time to get enough people enrolled in trials.
2) Lots of government funding support for the trials
3) FDA bumps to the front of the line for review.

So, yes, it was fast, but not due to cutting corners on collecting data.
You're kind of right about the long-term health effects data. That's why it's emergency use authorization. Still, they have some data in the 4 to 5 month timeframe, and so far, so good.
