1 doctor agrees

In brief: Recommend

The positive jcv test is indication of risk for pml if you continue tysabri, (natalizumab) and this can range from 1 in 90 to 1 in 400.
Would definitely get flu shot, not the nasal which is live, and risky. Remember that viral infections can readily promote relapses. Lastly, flu shot has no effect on the jc virus.
