Immunity

Complete the following discussions:

Vaccines are inactive or partially active forms of a pathogen that trick the immune system into acting early by producing antibodies. This allows a person’s immune response to prepare itself in case it encounters the natural pathogen.

  • Describe the differences between a live and dead vaccine. What are the risks associated with both vaccines?
  • What does herd immunity mean? Research the Centers for Diseases Control and Prevention (CDC) website for vaccine-preventable diseases and identify the diseases that are on the rise.

Autoimmune diseases occur when the immune system produces antibodies that attack the body’s own tissues. The signs and symptoms of autoimmune disorders depend on the type of cell that is affected.

  • Describe an autoimmune disorder, other than multiple sclerosis, colorectal cancer, psoriasis, asthma, respiratory syncytial virus infections, Crohn’s disease, and rheumatoid arthritis.
  • Describe a few symptoms of the disease.
  • apa format cite sources

MODEL ANSWER 

The difference between live and PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER how they are made. Live, attenuated vaccines contain a living, although significantly weakened, version of a virus or bacteria. Measles, mumps and chicken pox vaccines are made with live viruses. The benefit of a live vaccine is that a single dose often provides lifelong immunity. The PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER is that because viruses and other pathogens naturally mutate, or change, the virus within the vaccine could also change, creating a stronger version of itself that the immune PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER would have difficulty combating. This was an issue with the early oral polio vaccines, but is generally not a problem with current live vaccines, which are much safer PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER the virus they protect against.

Only people with a PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER immune system (such as those who have HIV, who are taking immunosuppressant drugs or who are being treated for cancer) should be concerned about receiving live vaccines because PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER could, conceivably, become infected with the PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER . These vaccines also usually require refrigeration. Inactivated vaccines contain a killed version of the pathogen. They are more stable (PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER they don’t need refrigeration) and safer than attenuated viruses, but they don’t cause as strong an immune response. Thus, the immunity they provide may not last as long and you might need a “booster” vaccine PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER the road……………PLACE ORDER FOR A COMPLETE AND CUSTOMIZED ANSWER ………………
