But nobody's gonna say no to an improvement that ups those odds. Say, a condom coated in antiviral gel that kills up t0 99.9% of HIV, genital herpes, and human papillomavirus. Australia just said yes, and hopefully the U.S. isn't far behind.
The key component here is VivaGel, an antiviral gel powered by nanotechnology. The gel's active ingredient is millions and millions of nano-sized molecules. These perfectly symmetrical 3D branching structures glom onto viruses like HIV, HPV, or the virus that causes genital herpes, preventing them from binding to human cells. No binding, no infection.
Step in the right direction for getting rid of stds.
