Serum and Vaccine how is get the Serum

The vaccine is used a cow this why the name. And the vaccine is the viruses weak so the body, the immune system, would get autoimmune to the viruses and when the person would came infected would already be autoimmune and the person would generate antibodies without even get sick, would be fast the reaction. And what is Serum? the serum is the antibody, is that way the serum is made from the blood of the horse, the horse has the immunological system better than ours and once inoculated the virus the immunological system of the horse would produce antibodies in a shorter time than the human and also the horse 40 litres of blood is not an amount like would be for an human, so the serum is transparent because the blood would be put in a centrifuge machine and would be applied only the plasma isn't needed the red globules that have shock if is negative positive A, B, AB, O. Also the serum is to be applied just after made because the antibody has to be alive. Rute Bezerra de Menezes Gondim
