Although the World Health Organization had recommended that every child be vaccinated for Hepatitis B by the early 1980s, large multinational pharmaceutical companies held monopolies on the recombinant Hepatitis B vaccine. At a price as high as USD$23 a dose, most Indians families could not afford vaccination. Shantha Biotechnics, a pioneering Indian biotechnology company founded in 1993, saw an unmet need domestically, and developed novel processes for manufacturing Hepatitis B vaccine to reduce prices to less than $1/dose. Further expansion enabled low-cost mass vaccination globally through organizations such as UNICEF. In 2009, Shantha sold over 120 million doses of vaccines. The company was recently acquired by Sanofi-Aventis at a valuation of USD$784 million.
The case study and grounded research method was used to illustrate how the globalization of healthcare R&D is enabling private sector companies such as Shantha to address access to essential medicines. Sources including interviews, literature analysis, and on-site observations were combined to conduct a robust examination of Shantha's evolution as a major provider of vaccines for global health indications.
Shantha's ability to become a significant global vaccine manufacturer and achieve international valuation and market success appears to have been made possible by focusing first on the local health needs of India. How Shantha achieved this balance can be understood in terms of a framework of four guiding principles. First, Shantha identified a therapeutic area (Hepatitis B) in which cost efficiencies could be achieved for reaching the poor. Second, Shantha persistently sought investments and partnerships from non-traditional and international sources including the Foreign Ministry of Oman and Pfizer. Third, Shantha focused on innovation and quality - investing in innovation from the outset yielded the crucial process innovation that allowed Shantha to make an affordable vaccine. Fourth, Shantha constructed its own cGMP facility, which established credibility for vaccine prequalification by the World Health Organization and generated interest from large pharmaceutical companies in its contract research services. These two sources of revenue allowed Shantha to continue to invest in health innovation relevant to the developing world.
The Shantha case study underscores the important role the private sector can play in global health and access to medicines. Home-grown companies in the developing world are becoming a source of low-cost, locally relevant healthcare R&D for therapeutics such as vaccines. Such companies may be compelled by market forces to focus on products relevant to diseases endemic in their country. Sanofi-Aventis' acquisition of Shantha reveals that even large pharmaceutical companies based in the developed world have recognized the importance of meeting the health needs of the developing world. Collectively, these processes suggest an ability to tap into private sector investments for global health innovation, and illustrate the globalization of healthcare R&D to the developing world.
尽管世界卫生组织早在 20 世纪 80 年代初就建议为所有儿童接种乙肝疫苗,但大型跨国制药公司对重组乙肝疫苗拥有垄断权。由于一剂高达 23 美元的价格,大多数印度家庭都无法负担得起接种疫苗的费用。成立于 1993 年的印度生物技术先驱 Shantha Biotechnics 看到了国内的未满足需求,并开发了制造乙肝疫苗的新方法,将价格降低到每剂 1 美元以下。通过联合国儿童基金会等组织的进一步扩展,实现了全球低成本大规模疫苗接种。2009 年,Shantha 销售了超过 1.2 亿剂疫苗。该公司最近被赛诺菲以 7.84 亿美元的估值收购。
本案例研究和扎根研究方法用于说明医疗研发的全球化如何使 Shantha 等私营部门公司能够解决基本药物的获取问题。包括访谈、文献分析和现场观察在内的多种来源相结合,对 Shantha 作为全球卫生适应症疫苗主要供应商的发展进行了全面研究。
Shantha 作为一个重要的全球疫苗制造商取得国际估值和市场成功的能力,似乎是通过首先关注印度当地的健康需求实现的。Shantha 如何实现这种平衡,可以从四个指导原则的框架来理解。首先,Shantha 确定了一个治疗领域(乙型肝炎),在这个领域可以实现成本效益,以满足穷人的需求。其次,Shantha 不断寻求非传统和国际来源的投资和合作伙伴关系,包括阿曼外交部和辉瑞公司。第三,Shantha 专注于创新和质量——从一开始就投资创新,获得了关键的工艺创新,使 Shantha 能够生产出负担得起的疫苗。第四,Shantha 建造了自己的 cGMP 设施,这为世界卫生组织的疫苗预认证建立了信誉,并引起了大型制药公司对其合同研究服务的兴趣。这两个收入来源使 Shantha 能够继续投资于与发展中国家相关的医疗创新。
Shantha 的案例研究强调了私营部门在全球健康和获取药物方面可以发挥的重要作用。发展中国家的本土公司正在成为疫苗等治疗方法的低成本、本地相关医疗研发的来源。这些公司可能会受到市场力量的驱使,专注于本国流行疾病相关的产品。赛诺菲收购 Shantha 表明,即使是总部位于发达国家的大型制药公司,也已经认识到满足发展中国家健康需求的重要性。这些过程共同表明,有可能利用私营部门投资进行全球健康创新,并说明医疗研发向发展中国家的全球化。
