That is true. However, the plasticy bandaid flavor is almost always your water quality, stressed yeast, or can also be just something plastic that got into your wort.
Another question, did you rehydrate the yeast before pitching? Rehydration isn't completely necessary, but it CAN give you a good indication if the yeast is healthy. I always rehydrate for this very reason. Even if you do it 15 minutes before pitching (being careful with the water temperature, don't go over 85 degrees) it should start working. If you've got little or no action 15 minutes after rehydrating, you're gonna have a bad time if you pitch it in your wort.
