Verez Bencomo is a chemist dedicated to understand the molecular basis of protection from infectious disease and to use this knowledge for the development of vaccines. He led this development from bench to introduction into preventive medical practice for 5 different vaccines: The first was Quimi-Hib, a conjugate vaccine against Haemophilus influenza type b using for the first time a synthetic carbohydrate antigen (Science, 2004) and prequalified by the World Health Organization. Quimi-Vio, a conjugate vaccine including the most prevalent Streptococcus pneumoniae serotypes actually in the last clinical steps before commercial introduction in Cuba. In the period 2020-2021 during the COVID19 pandemic, he also led the development of a series of 3 vaccines call SOBERANAS. SOBERANA 02 is the only conjugate vaccine developed. The safety record of this vaccine platform allowed a quick introduction in children in Cuba as early as September 2021 allowing Cuba to be the first country in the world mass vaccinating children against COVID-19. He is “Knight of the Legion of Honor”, (France, 2015) and “National Hero” (Cuba, 2021)
