Heart, Faith and Instincts Instead of "Science" in the Covid Situation

I feel that following our own hearts/faith/instincts is the best way to handle covid and all the other difficulties we are faced with. I do not have faith in the "science" of this covid situation, because the covid vaccines have not been approved for safety and even if they are, there is still just cause for concern due to the history of MANY other pharmaceuticals that had been declared safe but were later proven not to be.  "Science" has sometimes failed us, especially in the arena of man made medicines/pharmaceuticals.
