Today the world marks aids vaccine day, which aims at promoting the continued urgent need for a vaccine to prevent HIV infection and aids. The first world aids vaccine day was observed on May 18, 1998 to commemorate the anniversary of Clinton’s speech. Despite our major success in scaling up treatment and ongoing prevention programmes, experts lament there is still a large number of people getting infected with the virus.

New HIV infections have remained stubbornly high for the past 10 years. But continued research to find a vaccine for HIV. Although there have been significant discoveries in the field of vaccine research and development, there is still no effective vaccine available against HIV.

Every year, 1.9 million adults and more than 150 000 children become infected with the virus. even if a 90% reduction in new HIV infections is achieved by 2030, there will still be around 200 000 new HIV infections annually, demonstrating how essential a vaccine will be for the long-term control of HIV.

Over 35 years, research has proven that developing HIV vaccine is not easy .However trials that are ongoing in South Africa dubbed ‘‘Uhambo’’ the hvtn702 trial which results are expected in 2021. That trial, part of the HIV vaccine trials network, builds on the rv144 trial, which reported in 2009 and was conducted in Thailand, showing a 31% efficacy.

In 2009, the Thai vaccine trial, also known as rv144, showed proof of concept that a preventive HIV vaccine is possible. Researchers have continued to build on the result of that trial to refine and develop potential effective strategies.

And by adding new prevention options, such as oral pre-exposure prophylaxis (prep), into the standard prevention package of ongoing and planned trials. The joint United Nations programme on HIV/AIDs (UNAIDS) leads and inspires the world to achieve its shared vision of zero new HIV infections, zero discrimination and zero aids-related deaths. And by working closely with global and national partners towards ending the aids epidemic by 2030 as part of the sustainable development goals. The first world aids vaccine day was observed on May 18, 1998.
