It's not a live virus so it may just be coincidence that you got sick after?
You could have actually been getting sick prior to taking the vaccine. It can take 2 weeks for it to become effective,but you can also feel aches and sick because your body is working hard to make antibodies for that vaccine which is what you want. If that's the case it shouldn't last longer than a day or two
