The present invention relates to the treatment of the COVID-19, here, the inventors generated potent non-neutralizing pan-SARS-CoV-2 mAb, notably the antibody C10, targeting a conserved region of the virus. Noteworthy, C10 demonstrated remarkable efficacy in recognizing nearly all known variants of the virus and effectively binding infected cells. Leveraging this pan-SARS-CoV-2 mAb, they have engineered CAR-T cells capable of efficiently killing lung epithelial cells infected with the virus. Overall, their work identifies a pan-SARS-Cov-2 able to target bona fide infected cells and provides a proof-of-concept for the potential use of CAR-T cell therapy in combating SARS-CoV-2 infections. Their findings also highlight the potential of non-neutralizing mAbs in mediating immune protection against emerging infectious diseases. Thus, the present invention relates to anti-spike antibodies, particularly in a purified form or in an isolated form and their use to treat SARS-CoV-2. Particularly, the present invention is defined by the claims.

Samples of dehydrated blood films of patients with a history of COVID-19 are placed in the optical arrangement of a polarization Mach-Zahnder interferometer. A series of linearly polarized and circularly left- and right-polarized irradiating and reference laser beams are formed. For each polarization state, the irradiating beam is sequentially directed by a rotating mirror onto a sample of a dehydrated blood film, the laser images of which are projected by a polarization microlens into the plane of the photosensitive pixels of a digital camera. A series of reference beams are sequentially directed into the plane of the laser image of the dehydrated blood film using a rotating mirror, and interference patterns are formed that are transmitted by a linear polarizer in two rotations of the transmission plane to angles of 0° and 90°, which are sequentially recorded by the photosensitive pixels of a digital camera, with subsequent algorithmic digital holographic reproduction of layer-by-layer maps of linear birefringence of the structural an
