  • Texas
  • Ow, I need to get an antivenin for this snake bite
  • Doctor Zahos, I got a snake bite and it hurts. I think I need a vaccine.
  • No, not a vaccine. An antigen has entered your body meaning you will need an antibody, or some sort of leukocyte to neutralize the effects of the venom. Your body cannot react with a cell mediated response because you need an antibody.
  • Your body responds to foreign substances in two different ways: Nonspecific and specific immunity. 
  • What does that mean?
  • The main difference between the two is that nonspecific response is same for all pathogens while specific is different for all pathogens
  • I get it now. However, I heard rumors that I can only get the antivenin procedure once
  • Let me explain the process. The antivenin is made up of antibodies and goat serum. The goat makes the antibodies through a process called humoral response which uses helper T cells to make b-cells into plasma cells and memory b-cells, which remember the pathogen for making antibodies faster in the future. 
  • Antibodies basically neutralize foreign substances like bacteria and viruses. In your case, the snake bite triggers inflammatory reactions in your body which can be countered with an antibody. Cytotoxic T cells can also help as they act as a defense mechanism for fighting viruses and bacteria.However, you cannot get the antivenin/antibody twice because the body will treat the antivenin like an allergy and also it can cause inflammation.
  • Uh, Doc... can you explain to me what antibody is?
