no. what it does is gets the yeast back into suspension, rouses them, mixes them up and makes them get off their lazy asses and back to work.
some people worry about oxidation, but there is so much co2 in the head of your fermentation vessel that shaking it wouldn't even be a problem, let alone just a swirl. no oxygen will get in there.
good to see you are using your hydrometer and that you caught this. but patience is key. my advice is to rouse the yeast and let it sit another week, whether you are transferring to secondary or not.
