My concern is whether these monoclonal antibodies against the spike protein will worsen my existing autoimmune reaction caused by the Pfizer vaccine. Published research indicates I likely still have spike protein, which was produced by the vaccine, in my white blood cells. That spike protein is the target for the monoclonal antibodies in Evusheld. I talked to my rheumatologist about this issue and she said no one knows how I would react to the Evusheld product (another Emergency Use Authorization). A note of caution for the thousands of us who experienced severe adverse reactions to the Covid vaccines.
