They might interfere with oxygen delivery, which could explain some Long Covid symptoms such as brain fog. In November 2021 in The New England Journal of Medicine, he proposed that an autoimmune mechanism triggered by the SARS-CoV-2 spike protein might explain both Long Covid symptoms and some rare vaccine side effects, and he called for more basic research to probe possible connections. official website and that any information you provide is encrypted Dressen had never had COVID-19.
