Why is it so hard to find a AIDS vaccine?
When obtaining immune deficiency syndrome (AIDS), for the first time in the age of 20, in the 1880s. As the 90s were wore without a sign of vaccines against AIDS or treatment, some members of the public lost faith in public health facilities. With numerous vaccines on the market of other diseases, the lack of AIDS vaccine was questioned. The reasons for difficulty in developing AIDS are extremely complex and some scientists fear that the vaccine may not actually be developed.
The traditional vaccine is designed to prevent the disease, but not necessarily infections. For example, a vaccine against pediatric palsy introduces antibodies into the human body to help it fight childhood palsy when it is exposed to illness. Someone who has been vaccinated for palsy can still be infected with palsy, but the infection does not enter the nervous system and leads to childhood diseases. However, AIDS must prevent infection,Because the body cannot be learned naturally against the virus. Because AIDS works from the immune system, the body is unable to recognize and fight it.
The development of a vaccine that prevents infection is extremely difficult. Most AIDS experiments have shown that vaccination can be able to help avert progression to fully blown AIDS, but that the prevention of infection may prove to be a challenge. This is partly due to the way AIDS works. But it is also because of the nature of the virus itself. AIDS, unlike many other viruses that people have vaccinated, are very diverse and versatile.
AIDS originally developed in monkeys and, like other diseases of non -luminous origin, mutates very quickly to adapt to the differences of the human body. These quick mutations mean that the virus changes dramas five years after the development of the theoretical vaccine, it will be radically different, which will potentially make the vaccine unnecessary. AIDS is also divided into several groups or Clades . Each positive contains different genetic information, and while each has a geographical center, the effective AIDS vaccine would have to prevent infection from all AIDS pins, because of the global nature of human interactions.
Research for AIDS development continues, while scientists also work on drugs that can help treat the condition. However, many public health advocates moved their focus on preventive education rather than waiting for AIDS.
