The disclosures of the invention are directed to the manufacture of effective, affordable vaccines that are globally accessible. Using a platform conjugation technology, highly immunogenic conjugate vaccines were produced that elicit broad cross-neutralization to variants of concern (VOC), manufactured cheaply compared to mRNA vaccines. Protein-protein conjugates and Toll-Like Receptor (TLR) agonist adjuvants were shown to enhance immunogenicity and induce broad cross-protection against VOC, a characteristic lacking in early mRNA COVID-19 vaccines. Murine nAb titers from Beta-only conjugates were equivalent between Beta, Delta, Omicron BA.1, BA.2, and BA.4/BA.5, which were circulating up to three years after the antigenic strain. Additionally, Beta-Delta bivalent conjugate vaccines readily prevented disease in hamster challenge, which demonstrates a vaccine with remarkably broad cross-protection and potential to protect for extended periods despite mutations, without requiring expensive boosters or antigen adaption. This vaccine can be produced in our highly automated, large-scale manufacturing facility enabling economical production of inexpensive, effective vaccines for high-need areas.

Method for polarization-phase interferometry of the optically anisotropic architectonics of fibrillar and parenchymal tissue specimens from deceased individuals who suffered from COVID-19, by means of polarization mapping of laser microscopic images of native histological sections of biological tissues with algorithmic reconstruction of integrated average phase maps of the polycrystalline architectonics of biological layers through the measurement of coordinate distributions of partial elements of the polarization matrix. To evaluate changes in the layer-by-layer phase maps of the optically anisotropic architectonics of fibrillar (myocardium) and parenchymal (kidney) tissue specimens from the deceased, native histological section samples of deceased individuals who suffered from COVID-19 are placed in the optical beam path of a Mach-Zehnder polarization interferometer. A series of plane-polarized (with polarization azimuths of 0°, 90°, 45°, 135°) and circularly left-hand 5 and right-hand polarized irradiating and reference laser beams are formed; for each polarization state, the irradiating beam is directed by means of a rotating mirror onto the native histological section sample of the deceased who suffered from COVID-19, the laser image of which is projected by a polarization micro-objective into the plane of photosensitive pixels of a digital camera, while a series of reference beams with polarization states of 0°, 90°, 45°, 135°, a, , are sequentially directed by
