Hello, I'm a retired British doctor in previous very good health, now 73. I received the two Shingrix shots (new non-live vaccine) last August 2019, spiked a high temperature that night but then OK. However, within 3 weeks I'd developed the symptoms and distribution of polymyalgia rheumatica - pectoral and especially pelvic girdles, big muscle groups pain and stiffness. Playing piano fine, but buttocks painful on the piano stool. It's all still there 7 months later and I'm hobbling around - though fortunately I can control it on ibuprofen, so can avoid steroids.
There was a rheumatology conference in 2019 in Ohio where academics were expressing their worries about this vaccine. It's not the vaccine itself, but a new adjuvent (added to initiate the immune response) from a tree in Chile that promotes a very intense reaction and gives highly efficient protection. But the downside is that sufferers who already have auto-immune conditions could be made worse, and also that the vaccine could actually spark new auto-immune conditions such as kariski and I are experiencing.
