Why doctors donot have vaccine for aids?

They are waiting for you to get busy and isolate the hiv and find out how to kill this virus...so study hard in school .
we are all waiting on you!! I wonder if they have tried Bleach in an IV!!!
let us know first!! we are counting on you!!!!!

till now there is no cure 4 diseases caused by virus. so no cure 4 aids as it is caused by virus

Because it is a very complex virus that keeps changing. They're working on it, and have been for about 20 years now and there is hope that somewhere down the line there will be one.

No one has yet identified the "magic bullet" that will cure aids in all its forms.

becoz now ..they not made good "Q" ..of vac..

thats..
but one day ...AIDS HAVING VAC..

AIDS means anti immune deficiency syndrome in which the AIDS virus directly affects the immune system of the patients body and makes him very weak susceptible to fatal ones.
AIDS cannot be cured because it is very difficult to detect the virus itself as it changes its shape and form every now and then due to which delay in diagonising the patient takes place and till that time he has already reached the last stages of AIDS and then none of the vaccines or medicines work because the whole of immune system has become so weakthat the body cannot even resist the load of the medidcine so there is no way of curing it.

why do want 2 get vaccinated for aids, even if un is developed for (which dere is no hope) why will a boy/gal tk it du u plan 2 lead a promiscous life !! tk precautions and live long ! never mind here is d answer.
Vaccines are small amount of antigens ( actually desease virus) injected in ur system so that ur body can produce antibodies to counter them. Once so produced antibodies remain in d system and can fight the particular antigen.
Therefore you are actually exposed to limited onslaught so that u survive a bigger one.
The catch is ur body should b able to counter the antigen and produce the antibodies through its own immune system .
In aids ur immune system itself is attacked by deadly HIV . There is no antibody ur body can produce for HIV nor is able to produce for other ailments too since immune system is attacked ( Acquired Immune Deficiency Syndrome)
Now if u are infected ( hope you wont be ever) no vaccines or antibiotics work on you.
You are simply exposed to any ailment ( sardi khasi malaria ....leave aside the HIV.

no vaccine has been developed so far, but they are working on it

HIV, the virus responsible for AIDS mutates so rapidly,its nearly impossible to produce a vaccine that will be uniformly effective.

A lot of research is being done in order to develop a vaccine for AIDS. There is a long study and proper processthat has to followed and obtain a drug or a vaccine after development it has to be approved by the health care authorities , all this takes a lot of time hard work and special talents . Work is in progress with no constructive results as of today.

Because they still are not able to develop and "antibody" like substance to combat its virulent effects. But the research is an ongoing project and who knows? perhaps next month, they will discover it.

The ineffectiveness of previously developed vaccines primarily stems from two related factors. First, HIV is highly mutable. Because of the virus' ability to rapidly respond to selective pressures imposed by the immune system, the population of virus in an infected individual typically evolves so that it can evade the two major arms of the adaptive immune system; humoral (antibody-mediated) and systemic (mediated by T cells) immunity. Second, HIV isolates are themselves highly variable. HIV can be categorized into multiple clades and subtypes with a high degree of genetic divergence. Therefore, the immune responses raised by any vaccine need to be broad enough to account for this variability. Any vaccine that lacks this breadth is unlikely to be effective.

researchers have many different strategies that may lead to an effective HIV vaccine. Scientists take small parts of the HIV virus and alter them in a laboratory to create synthetic copies. The experimental vaccines do not use whole or live HIV. The vaccines cannot cause HIV or AIDS. The vaccines being tested should produce either antibodies* or cytotoxic T cells (CTLs) to fight infection..some other researches are going..
