- 4,115 people have been hospitalized or died with Covid-19 despite being fully vaccinated.

- 76% of hospitalizations and deaths from breakthrough cases occurred in people over the age of 65.
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.
