It wasn't rushed, the science was ready to go early last year and all they did was accelerate the first trial phases, the Phase 3 trials went quickly because infections were so widespread.
That there are multiple candidate vaccines targeting the spike protein without using the virus directly is strong evidence that the science was ready (using mRNA, viral vector and other technologies).
