With an estimated 2.7 million HIV infections constantly cropping up globally every year, revolutionary new approaches have been adopted towards putting a plug on this life threatening menace. Many strategies are being employed to create potent anti aids vaccine which will aid in averting it. Miniature versions of the HIV virus are taken and modified in laboratories to develop synthetic copies. The process does not involve using the whole or live vaccine. The vaccine being tested will have the ability to effectively produce either cytotoxic T cells or antibodies that will aid in combating the infection. Types of investigation HIV vaccine strategies: Peptide vaccines have been developed from minuscule pieces of proteins taken from the HIV virus. A recombinant sub-unit protein vaccine which is under way makes use of bigger parts of proteins that are situated on the surface of the HIV virus. The recombinant vaccine versions gp 120, gp 140 and gp 160 developed by genetic engineering  [...]
