if a child has system has a very weak immune system and he is given vaccinationcan the microbes that are injected in his body may cause him that particular diseases
Vaccines does not cause any diseases as the vaccines are a suspension of killed or attenuated microbes, or a substance that mimics the disease-causing microbes. Vaccines stimulate and strengthen immune response produced by the body. When a vaccine is administered into our body the white blood cells (WBCs) get to work and produce antibodies against weakend microbe present in the vaccine. The antibodies produced against the antigen form a memory of the microbe and remember it and when the same disease causing antigen (microbe) strikes again, the body reacts with greater vigor to eliminate the disease. Thus preventing the child from the disease.
