Severe Acute Respiratory Syndrome Coronavirus 2 Nosode: A Potential Alternative Vaccine Platform

Besides conventional vaccinations, viable alternatives are needed to elicit an immune response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We propose and highlight the value of a homeopathic approach known as the "nosode" for the prevention of coronavirus disease-2019 (COVID-19). Nosode is an extract prepared from disease-affected tissues which is subsequently processed and administered as an antidote for the same medical condition. This concept might be a crucial therapeutic approach for viral infections since infected tissues contain a wide range of important viral antigens that could induce a functional host response via immunological sensitization. Thereby, nosode preparation produced from SARS-CoV-2-affected tissues may provide protection against COVID-19. "SARS-CoV-2 nosode" warrants more scientific investigation as a viable alternative vaccination platform. Keywords: COVID-19, Nosode, SARS-CoV-2, Variolation.
