These Vaccines protect individuals who do not have HIV from contracting that virus,or therapeutic effect for persons who have or later contract HIV. There is no effective HIV vaccines currently, but research projects on clinical trials are trying to build one. There is evidence that a vaccine may be possible. Preventative medications such as antiretroviral treatments have been put into use to help prevent infection, but do not work as well as a vaccine would. The need for advance purchase commitment is a challenge in production of vaccines because governments bring the price down to marginal cost after the vaccine is being developed. Recognition of viral proteins causing various diseases by priming acquired immunity through vaccines has failed in the case of HIV. Some have stated that an HIV vaccine may not be possible without significant theoretical advances.
