A recent study published in the journal 'Nature' has revealed one of the most astonishing and surprising fact.
The study conducted by a team of researchers from the International AIDS Vaccine Initiative (IAVI), Scripps Research Institute and Texas A&M University have showed how they were able to induce antibodies and prevent HIV infections.
One of the most challenging aspect faced by researchers in terms of HIV vaccination is that people who are infected do not efficiently make antibodies against the virus.
During the study researchers found that the cows' immune system can produce powerful, HIV-blocking antibodies within a matter of weeks, giving hope for the development of a broadly effective AIDS vaccine in the near future. The similar process in the human body would usually take years.
However, till date the scientists were not able to successfully induce the creation of bNAbs in humans through an HIV vaccine.
For the study, the researchers had injected four calves with HIV immunogens, which are proteins designed to elicit an immune response to the virus. They found that the cows quickly developed bNAbs to HIV in their blood.
The researchers were able to isolate antibodies from the calves and took a closer look. An antibody called NC-Cow 1 was revealed to be especially powerful when it came to attacking HIV.
