Interesting, every terrible side effect is 'just a coincidence' https://www.mayoclinic.org/diseases-conditions/guillain-barre-syndrome/symptoms-causes/syc-20362793 "The exact cause of Guillain-Barre syndrome is unknown. But two-thirds of patients report symptoms of an infection in the six weeks preceding. These include respiratory or a gastrointestinal infection or Zika virus. There's no known cure for Guillain-Barre syndrome, but several treatments can ease symptoms and reduce the duration of the illness. Although most people recover from Guillain-Barre syndrome, the mortality rate is 4% to 7%. Between 60-80% of people are able to walk at six months. Patients may experience lingering effects from it, such as weakness, numbness or fatigue."
