Why HAART regimen of drugs is given ?
HIV virus is known to develop resistance to drugs very fast, so that the HIV virus can grow even after taking that a drug for which HIV virus developed resistance.Hence even if one class of drug develops resistance HIV virus is likely to be stopped from further growth by other class of drug and so on , but there are certain limitations of every class of drugs so that they are able to control multiplication of HIV virus till some steps but not at all steps .
Hence combining all drugs those drugs which are acting at different levels in life cycle of HIV virus are formed to make a combination that is able to stop HIV virus from growth at all possible steps in HIV virus life cycle.
Hence HAART is the main therapy today available for treatment for HIV infection.
Till today there is no vaccine available for treatment of HIV infection, until today vaccines developed against HIV virus could not prove its beneficial effects in clinical trials.
