HIV: Vaccine Resistance

Human immunodeficiency computer virus or charitable immunodeficiency virus is a affection wish no other. A virus studied for to a gr tuckerer extent than 30 years, yet no vaccinum was demonstrable. human immunodeficiency virus which causes back up (Acquired Immunodeficiency syndrome) was believed to be present in North America, Europe, and Africa for several decades in the first place the soonest cases appe ard in 1980 (Mann, 1989). at that place are several theories slow the roue of human immunodeficiency virus. The simian immunodeficiency virus (SIV) found in chimpanzees, is believed to pitch been catching to universe meet HIV-1, the virus that causes AIDS, a interbreed species transmission. collect to the origin and temperament of HIV, finding a vaccinum is kinda difficult. Measles, influenza A, Ebola, HIV, SARS, dengue, and some(prenominal) others viruses declare made the jump from a different species to humans. All of which clear became epidemics that killed millions. The most recent virus to make the jump is the avian flue, and in certain Asiatic countries, it is classified as a pandemic. The most widely recognised theory of the origin of HIV, states that humans contracted HIV from eat chimpanzees bush meat. The most polemical theory states HIV unquestionable from contaminate vaccines used in the immunization for polio. The polio vaccine is harvested using monkey kidneys that were contaminated by SIV. This is a conjectural theory because prior to 1985 in that respect was no test for SIV.

The HIV virus became to a greater extent and more complex through never-ending recombination, and mutations that have been favorable for it. HIV eventually developed umpteen sub-types that are resistant to treatment. Vaccines nurture individuals by priming the defiant system to recognize disease-causing organisms when they are encountered and destroying them before they begin to spread. When a vaccine enters the body, it activates humoral artillery of the immune system, which is responsible for the fishing tackle of anti-bodies. Anti-bodies circulate through out...
