HIV vaccine development is an active area of research and an important tool for managing the global AIDS epidemic. Research into a vaccine for HIV has been ongoing for decades with no lasting success for preventing infection. [151] The rapid development, though, of mRNA vaccines to deal with the COVID-19 pandemic may provide a new path forward.
Criminal transmission of HIV is the intentional or reckless infection of a person with the human immunodeficiency virus (HIV). Some countries or jurisdictions, including some areas of the United States, have laws that criminalize HIV transmission or exposure. [298] Others may charge the accused under laws enacted before the HIV pandemic.
HIV is commonly transmitted via unprotected sexual activity, blood transfusions, hypodermic needles, and from mother to child. Upon acquisition of the virus, the virus replicates inside and kills T helper cells , which are required for almost all adaptive immune responses .
An HIV vaccine is a vaccine that would be given to a person who does not have HIV, in order to confer protection against subsequent exposures to HIV, thus reducing the likelihood that the person would become infected by HIV. Currently, no effective HIV vaccine exists. Various HIV vaccines have been tested in clinical trials almost since the ...
The earliest, well-documented case of HIV in a human dates back to 1959 in the Belgian Congo. [169] The virus may have been present in the United States as early as the mid- to late 1960s, as a sixteen-year-old male named Robert Rayford presented with symptoms in 1966 and died in 1969. [170]
Three women who were diagnosed with HIV after getting “vampire facial” procedures at an unlicensed New Mexico medical spa are believed to be the first documented cases of people contracting ...
Common side effects include headaches, fever, and nausea. [6] Serious side effects include liver problems, muscle damage, and high blood lactate levels. [6] It is commonly used in pregnancy and appears to be safe for the fetus. [6] ZDV is of the nucleoside analog reverse-transcriptase inhibitor (NRTI) class. [6]
Research on the development of an HIV-1 vaccine has sought to replicate virus-specific CD8+ T-cell responses, which play a role in the control of HIV-1 replication. [10] Superinfection case reports have shown that superinfecting strains generally had different viral epitopes from the initial infecting cell. [10]
