Guenter GR: "The best Long Covid study to date has now been published, with surprising results that enable new therapeutic approaches. In simple terms: Long Covid is caused (in the areas studied) by autoantibodies in the blood, which then attack very important parts of the brain and can actually explain all the symptoms."
"Key insight: Long Covid patients must absolutely not donate blood, because it appears to be transmissible via those autoantibodies in the blood!"
