Lavax Inc is a small company whose primary focus is on probiotics research for medical applications. Lavax investigates applications in sexual health and fighting infectious diseases, and cancer. Lavax is developing and testing a vaginal suppository that uses a strain of commensal bacteria which has the ability to immobilize sperm and capture viruses. If successful, the bacteria could be used as a reversible contraceptive that also affords protection against viruses such as HIV and herpes. Lavax has developed a natural food substance that reduces HIV viruses in the motherâs milk, and will test it along with scientists at University of Toledo for its ability to block HIV transmission from mothers to infants
