SAN DIEGO and MEXICO CITY, Nov. 12, 2021 (GLOBE NEWSWIRE) — Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”) and the World Boxing Council (“WBC”) announced today that Sorrento’s COVI-STIX COVID-19 Virus Rapid Antigen Detection Test (“COVI-STIX”) will be used for screening all attendees of the upcoming 59th World Boxing Council Annual Convention in Mexico City, Mexico (November 14th through November 18th). The pandemic brought the world to a standstill and while most sports froze, boxing remained active through efforts by promoters, boxing commissions and the WBC. Boxing leads the world of sports in administrative and medical protocols to allow boxing matches to be held in bubbles without fans present. Testing is and should remain a major factor for the successful organization of any public event, including boxing events with audiences present at maximum capacity. Sorrento Therapeutics Mexico has teamed with the WBC to provide COVI-STIX rapid testing for the event and have together committed to be very active in providing solutions to the boxing industry, as well as other sports and entertainment focused events. COVI-STIX tests will be administered to all convention attendees prior to registration and a local testing laboratory will provide testing and travel certificates to all foreign visitors requiring proof of testing for international travel. Many superstars will be in Mexico City to attend the “Together Again” convention, including Floyd Mayweather, Julio César Chávez, Oscar De La Hoya, Larry Holmes, Roberto Durán and Antonio Tarver, among many other heroes from yesterday and today who will be in attendance, including boxing’s biggest superstar Canelo Álvarez.
