I had the first dose of Shingrix on October 30, 2018. I imediatley had an allergic reaction. The next norning I fell to the floor after waking up and wound up in the ER with such severe vertigo that I wasn't sure I could survive it. Was diagnosed with vestibular neuropathy by my ENT doctor. Eventually I tried physical therapy which helped but didn't stop the spinning from occuring on occassion. My primary care doctor prescribed 2 mg of Valium at bedtime which seems to help. However, it's been four years and I still can't look up at the sky, watch my grandkids on the merry go round, bend over from the waist and then suddenly straighen up, etc. Neither GSK nor VAERs seemed the least bit interested. I didn't get the second Shingrex vaccination and have no plans to do so. Waiting for the class action suit against GSK which I WILL join!
