You are scaremongering. The urgency of the situation has galvanised research workers and the approval system, and corners have not been cut. The science has been utterly amazing. If we waited for your suggested five years, millions more people may die. There's far too much of your kind of bollix being propagated and it's very worrying that it's spreading like wildfire from social media on to community forums like this one. Your choice: don't have the vaccine and let the rest of us move up the queue. Fine by me.
