Cell-mediated immunity (CMI) response of healthy humans and cancer (Ca) patients to specific tumor antigen and nonspecific (LDV -- lactate dehydrogenase virus) antigen, and of acute myocardial infarction (AMI) and schizophrenia (Sch) patients to nonspecific antigen was investigated. Large differences of CMI response of healthy humans in comparison with Ca, AMI, Sch patients were found. CMI response to antigens displays transferred information about cells under immune surveillance. LDV disturbs the oxidative energy production system. We assume that CMI response to LDV antigen monitors pathological states of mitochondrial energy production which results in disturbances of electromagnetic activity of living cells.
Covid-19 or SARS-CoV-2, a new RNA virus with high infectivity, and seemingly low mutability, which appeared in 2019 in the Wuhan province of China, has created a pandemic with dire consequences. At the end of May 2020, it became the first cause of mortality. As no treatment or vaccine may become available before many months, and because occurrence of similar pandemics is only a matter of time, arguments are presented here for testing the effect of transfer factor (TF), an immunomodulator devoid of toxicity, which has been extensively studied in the past for the treatment and prevention of viral infections.
