Bonus article #2

The article “Biological catch-22 prevents induction of antibodies that block HIV” explains that the potentially life saving vaccine against AIDs may be blocked by the body. As soon as HIV-antibodies are created the immune system works to destroy them before they mature. This helps to further understand how HIV develops in the body. It has recently been theorized that, according to Duke University researchers, “the antibodies required to broadly neutralize HIV may not be produced in the first place because the immune system "sees" them as a potential threat -- due to their similarity to antibodies that promote autoimmune disease -- and destroys them.” This is a brilliant way for HIV to avoid the immune system; the antibodies needed to fight HIV are destroyed. Most of these rare B cells are deleted, but some survive and remain in a “turned off” stage. Thus, researchers are trying to discover how these cells may be able to be turned on continuing the search for preventative care. The CDC focuses on preventing infection through choices rather than via a vaccine, as one has not been sufficiently made. It is stated that abstinence, monogamous relationships with an uninfected partner, and refraining from sharing needles are the best way for individuals to stay safe, preventing HIV infections and the transmission of HIV.
