Tech Guruji's video: cow blood used in vaccine calf serum

Hey dosto, Note - This video is all about educational purposes only. The science behind the use of newborn cattle blood Covaxin falls in the category of inactivated vaccines, in which the pathogen is deactivated so that it can no longer cause infection. However, parts of the virus can still be identified by the body’s immune system, triggering a reaction. To produce the vaccine, vero CCL-81 cells — a line of cells from the kidney of a normal adult African green monkey — are grown in the lab. These cells are then exposed to the SARS-CoV-2 virus in bioreactors under controlled conditions. The virus is then harvested after about 36 hours and inactivated. The inactivated virus is mixed with adjuvants — substances known to enhance immune response. In the case of Covaxin, the adjuvants used are alum and a molecule known as imidazoquinoline, which helps the body better recognise RNA from viruses. To grow cells in the lab, scientists need to provide conditions that allow cells to divide and turn into specific cell types required for their experiments. For Covaxin, scientists used Dulbecco’s Modified Eagle Medium (DMEM), along with 5-10 per cent newborn calf serum. DMEM contains several essential nutrients required for cell division. However, cells in multicellular organisms, in addition to depending on nutrients for division, require certain other special molecules called ‘growth factors’ to trigger individual cell types. Cells have receptors that respond to different growth factors. By regulating these growth factors, scientists can control what type of cells will grow. covid 19 vaccine made from blood which vaccines contain blood products monkey kidney cells in vaccines use of animals in vaccine production bovine vaccines is there blood in vaccines fetal bovine serum side effects icmr covid vaccine ingredients Note : This video is only for information.
