I'm so sorry about your colleague. I developed sensory and motor polyneuropathy after the Covid vaccines. I have not had Covid. I was initially monitored for progression to CIDP and offered the pulsed prednisone infusions. However, my condition continues to improve. There are thousands of patients who suffered neurological injuries from the Covid vaccines who are members of two Facebook groups, e.g. Neuro V Long-Haulers. The V is an abbreviation for vaccines to avoid the Facebook censors in collusion with the government. The government is currently being sued for silencing the vaccine-injured.
