Scientists identify new hope for a universal HIV vaccine

Researchers are now focusing on developing antibody-based vaccines that will target the protein envelope of the human immunodeficiency virus (HIV), according to a recent study published in the journal PLoS One.

The investigators explained that many vaccines have focused on these proteins because they are key to inhibiting the rapid reproduction and mutation of the virus within cells.

The team of researchers said they expected that a combination of millions of identical antibodies, known as a monoclonal antibody, would provide protection against that specific strain of the viral infection. However, laboratory primates that were injected with these vaccines were found to effectively resist both the designated breed and several other subtypes.

The study's findings suggest that these forms of targeted vaccines may be able to protect individuals all over the world against different strains of the initial virus that causes AIDS.

Available treatments may reduce the symptoms of people who are HIV-positive and help delay the onset of AIDS. HIV is spread through the exchange of body fluids between an infected individual and another partner, most often by sexual contact.

Anyone who would like to be screened for HIV or other sexually transmitted diseases may consider using online testing services.
