The role and impact of polyethylene glycol on anaphylactic reactions to COVID-19 nano-vaccines
Very interesting reading.
"OLP/LM are common conditions with a prevalence of 0.2%–5.0%. Although the etiopathogenesis of OLP/LM is not fully understood, type 1 immune response appears to play a major role. Autoimmunity has been proposed to be the underlying mechanism of OLP/LM development. This series suggests that OLP/LM may be aggravated due to immune response to COVID‐19/vaccination."
"While it is not possible to establish causality between COVID‐19 infection/vaccination and OLP/LM development/exacerbation, the timing of events is an important consideration. Whether COVID‐19 infection/vaccination and OLP/LM development/exacerbation are directly or indirectly related, it is important to be aware of the occurrence of such events for diagnosis and management"
This study is of 7 total patients. Four had experienced this condition prior to be being vaccinated. Two of the three "new onset" patients developed the symptoms post infection with the Covid virus.
