evidence: The capacity of the hemoglobin protein to bind and release oxygen is tightly associated with its structure and to the conformational changes it undergoes when bound. According to Mike Adams, the author of the Natural News article, 5G radiation exposure "occupies the hemoglobin molecule with other elements that alter its structure and therefore its function, inhibiting its ability to bind with oxygen." The author further states that this binding deficiency is what makes people vulnerable to COVID-19: "This is very likely happening all across the world wherever 5G is currently functioning, it’s just that the coronavirus is now exacerbating the symptoms and conditions to the point where mass death is occurring." [...] In summary, the article does not provide adequate scientific evidence to support its claim that 5G increases vulnerability to COVID-19. In addition, no scientific studies have established an impact of 5G electromagnetic radiation on hemoglobin structure. Although research on the potential health impacts of EMF remains relevant, the characteristics of the EMF used in 5G suggest that it is unlikely it would cross the thickness of the skin and reach the blood, nor that it could alter the structure of biomolecules in vivo. The strength of radiation required to alter the structure of biological macromolecules is far higher than that used in telecommunications. Finally, 5G is not available in most parts of the world and the regions that do have it are not hotspots for COVID-19.
