hiv vaccine
...t is not expected to be approved any practical vaccine for years. The ability to develop effective vaccines would be enhanced by an understanding of what specific immune responses correlate with vaccine-induced protection. Additional research is also needed to identify how innate immunity could be controlled to develop effective HIV vaccines. An established agreement should be made on vaccine characteristics that vaccine should be based on. Researchers who are working on Aids are hopeful to find a vaccine that would treat people diagnosed with HIV and helps to prevent the spread of HIV. An effective HIV- vaccine must target two components of the immune system. One is to induce T-cell responses (cellular immunity). The second one is to induce production of antibodies (humoral immunity) that recognize and destroy antigens. There are two types of possible vaccine to be made: Therapeutic vaccines for HIV- positive patients and Preventive vaccines that protect people who are HIV-negative and would prevent then from being contaminated with the virus. So in order to produce an effective HIV-vaccine, it is required to get a deep understanding of HIV envelope protein that interacts with cellular receptors, which are recognized by antibodies.
