|Vaccines are the best weapons to protect the individuals against infection or disease by stimulating the bodyâs immune system. Unfortunately, vaccines against HIV are in various stages of clinical trial, but none of the trails were successful to provide protection against HIV. Researchers do not have clear initiative as the virus has unique ways of evading the immune system, and the human body seems to be incapable of mounting an effective immune response against it. NIAID, UNAIDS and WHO support many biomedical research works to develop an effective, safe and durable vaccine against the HIV by enhancing the effectiveness of existing prevention strategies to control the HIV/AIDS.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
