I went for my physicals today and my physician administered a dTAp/whooping cough combination vaccine to me. Later I also went for my ortho checkup (suffering from very bad should pain for weeks). My ortho physician has given me a predisone dosage for 10 mg tablets, total 14 tablets, tapering dosage.

I have heard prednisone lowers the immune system, can I start it so soon after taking my vaccination. Hoping to cure my shoulder pain but dont want to end up having whooping cough... or something worse...

Thanks for your help.
