An HIV vaccine that has the potential to protect people around the world from the virus has shown promising results.
A recent study found that treatment, which aims to provide immunity against various strains of the virus, produced an anti-HIV immune system response in tests on 393 people.
All of the vaccine combinations produced an anti-HIV immune system response and were found to be safe.
More testing is now needed to determine if the immune response produced can prevent HIV infection in people.
