Extracts from the common dandelion plant can prevent infection of various SARS-CoV-2 variants. That is the result of in vitro studies from two institutions in Germany, the Molecular Preventive Medicine of the University of Freiburg and the Food Chemistry and Molecular Sensory Science of the Technical University of Munich. In the study, extracts from the…
Antibodies and T- cells are produced in response to viral infections and immunizations, and they are specific to the protein sequences of each virus. The immune system “reads” those protein sequences during infections and immunizations and makes particular antibodies and T cells specific to them. The immune system also retains the information in its memory….
Recent studies are starting to say that the neutralizing antibodies elicited by prior COVID-19 infections and vaccinations are ineffective against the omicron variant. I talked about them at Study shows absence of omicron neutralization with the Pfizer and AstraZeneca shots, and Omicron can evade antibodies from vaccinated and COVID convalescent people. But, there is more…
New research from the University of Oxford, Reduced neutralisation of SARS-COV-2 Omicron-B.1.1.529 variant by post-immunisation serum, showed that Pfizer and AstraZeneca vaccination antibodies are ineffective against the omicron variant. It is available as a preprint from medRxiv. They studied serum among people given the Pfizer BNT162b2 shot (n=21) and the AstraZeneca AZD1222 jab (n=22). The…
Dr. Angelique Coetzee of South Africa is credited with discovering the omicron variant among her patients. ABC Radio National interviewed Dr. Coetzee about the omicron cases that she has seen. She said most have mild symptoms like fever, fatigue, headaches, body aches, and nausea. No one showed symptoms commonly seen with the Delta variant: “No…
