The original company name, Tetraheed Medical LLC, was chosen and intended to NOT attract attention, so that we could "fly under the radar" until we were ready to announce who we are, and what we are doing. Those announcements are occurring at the World Vaccine Congress 2026, in Washington DC, on March 30-April 2. In March of 2026, the company name was officially changed to Precision-Guided Vaccines LLC, and our website was moved to the site in the link above. If you click on that link, it will take you to our new site. And, welcome!
