Great post! Also great translation @egotheist! Sorry for suggesting another topic that may be interesting. There are studies that tested a live vaccine against HIV. Researchers took lactiv acid bacteria (LAB) and genetically modified them to present a certain HIV protein. They then vaccinated animals´ vaginas with these modified LABs and observed resistences. This is helpful as it can help to stop infection at the primary site of infection, the mucosal lining in genitals, mouth, nose and intestine. Cheers!
