No, there aren't. HIV mutates too quickly, and there are too many strains of it, for a vaccine to work. It probably isn't possible to make a vaccine for it.
No, it's not because big pharm is keeping back the drugs. People tend to forget - employees of pharmaceuticals are affected by AIDS just like the general population. If they had a cure, that wouldn't be the case - pharm employees and their family members would mysteriously have much better luck with HIV.

there are some number of vaccines being tested in different parts of world,but none of them has been reported to be perfect to cure AIDS.there are medicines and vaccines which can increase ur life to some extent but are much effective only if taken under proper presciption and hospitilisation.there are just preventive measures to aids.

No, there are no vaccine's for AIDS to prevent it or cure it. There are medications to help prolong your life for a while, but no cures or preventions as of date that are proven.

There is currently no vaccine against HIV or AIDS. The only known methods of prevention are based on avoiding exposure to the virus or, failing that, on an antiviral treatment directly after a highly significant exposure. Also, not a single case has been documented in which systemic HIV infection has been cured and even on the theoretical level, no plausible way of eradicating HIV infection has so far been found. Treatment for HIV can suppress viral replication to a degree sufficient to apparently stop disease progression, but success is critically dependent on the patients ability to keep perfect adherence to their drug schedule, which many people will fail to achieve. Also, modern combination therapy has been around for merely ten years, so it is not presently known whether treatment failure or inacceptable long-term side effects can be avoided in the majority even of perfectly compliant patients over a time-span of potentially many decades. However, it is known that without major medical and scientific breakthroughs, HIV will not have any problem surviving combination therapy for said decades. Still, in western countries, most patients survive many years following diagnosis because of the availability of the highly active antiretroviral therapy (HAART).[21] In the absence of HAART, progression from HIV infection to AIDS occurs at a median of between nine to ten years and the median survival time after developing AIDS is only 9.2 months.[7] HAART dramatically increases the time from diagnosis to death, and treatment research continues.
Current optimal HAART options consist of combinations (or "cocktails") consisting of at least three drugs belonging to at least two types, or "classes," of anti-retroviral agents. Typical regimens consist of two nucleoside analogue reverse transcriptase inhibitors (NRTIs) plus either a protease inhibitor or a non-nucleoside reverse transcriptase inhibitor (NNRTI). This treatment is frequently referred to as HAART (highly-active anti-retroviral therapy).[72] Anti-retroviral treatments, along with medications intended to prevent AIDS-related opportunistic infections, have played a part in delaying complications associated with AIDS, reducing the symptoms of HIV infection, and extending patients' life spans. Over the past decade the success of these treatments in prolonging and improving the quality of life for people with AIDS has improved dramatically.[73][74]
Because HIV disease progression in children is more rapid than in adults, and laboratory parameters are less predictive of risk for disease progression, particularly for young infants, treatment recommendations are more aggressive for children than for adults.[75] In developed countries where HAART is available, doctors assess the viral load, rapidity in CD4 decline, and patient readiness while deciding when to recommend initiating treatment.[76]
There are several concerns about antiretroviral regimens, as side effects of these antiretrovirals have caused problems such as lipodystrophy, dyslipidaemia, insulin resistance, an increase in cardiovascular risks and birth defects.[77][78] Regimens can be complicated, requiring patients to take several pills at various times during the day, although treatment regimens have been greatly simplified in recent years. If patients miss doses, drug resistance can develop contributing to the rise of viral escape.[79][80] Anti-retroviral drugs are expensive, and the majority of the world's infected individuals do not have access to medications and treatments for HIV and AIDS. Research to improve current treatments includes decreasing side effects of current drugs, further simplifying drug regimens to improve adherence, and determining the best sequence of regimens to manage drug resistance.
A number of studies have shown that measures to prevent opportunistic infections can be beneficial when treating patients with HIV infection or AIDS. Vaccination against hepatitis A and B is advised for patients who are not infected with these viruses and are at risk of getting infected. In addition, AIDS patients should receive vaccination against Streptococcus pneumoniae and should receive yearly vaccination against influenza virus. Patients with substantial immunosuppression are generally advised to receive prophylactic therapy for Pneumocystis jiroveci pneumonia (PCP), and many patients may benefit from prophylactic therapy for toxoplasmosis and Cryptococcus meningitis.
Various forms of alternative medicine have been used to try to treat symptoms or to try to affect the course of the disease itself, although none is a substitute for conventional treatment.[81] In the first decade of the epidemic when no useful conventional treatment was available, a large number of people with AIDS experimented with alternative therapies. The definition of "alternative therapies" in AIDS has changed since that time. Then, the phrase often referred to community-driven treatments, untested by government or pharmaceutical company research, that some hoped would directly suppress the virus or stimulate immunity against it. These kinds of approaches have become less common over time as the benefits of AIDS drugs have become more apparent.
Examples of alternative medicine that people hoped would improve their symptoms or their quality of life include massage, herbal and flower remedies and acupuncture;[81] when used with conventional treatment, many now refer to these as "complementary" approaches. None of these treatments has been proven in controlled trials to have any effect in treating HIV or AIDS directly.[82] However, some may improve feelings of well-being in people who believe in their value. Additionally, people with AIDS, like people with other illnesses such as cancer, sometimes use marijuana to treat pain, combat nausea and stimulate appetite.
