@keepinghealthy3332 8 months is the time between EUA and now, not how long it was in development total. They started developing it months before the EUA, meaning it has been tested for over a year. Their clinical trial alone started almost 14 months ago.
They were also allowed to run concurrent testing. Before the clinical trials cellular and animal trials took place over the course of 3 months, pushing total development time to 17 months. These also overlapped considerably due to Operation Warp Speed.
This is not an unreasonable amount of time considering the overlapping testing and huge number of people in the clinical trial. Vaccines also don't need stage 4 trials as we aren't giving the vaccines to unhealthy people, but to people not yet infected. Usually clinical trails for new medications take so long because the testing pool is expanded several times, putting clinical trials into 4 separate phases. They practically leapt to stage 4 trails, cutting of years of clinicals. Then they skipped stage 4 all together, saving years of work.
For reference, mumps took 4 years to develop, and that was in the 60s without modern technology, massive bursts of funding and an immediate need.
