Medical Network July 15th, the US Johnson & Johnson subordinate Yangsen company said on the 12th, plans to conduct a phase III clinical trial of experimental AIDS vaccine in several countries in Europe and America this year. This preventive vaccine is designed to be a universal AIDS vaccine against multiple HIV strains.

Anthony Forge, director of the National Institute of Allergy and Infectious Diseases, told US media that it plans to recruit about 3,800 high-risk men to get the vaccine. The institute will work with Janssen.
According to a press release issued by Yang Sen, the vaccine is a “mosaic vaccine†that splicing the genes of different HIV strains to induce an immune response against a wider range of HIV strains. The vaccine achieved good protection in animal experiments and verified safety in human trials that have been carried out.
