BioProcess International recently took a look at the growing manufacturing demand in developing countries of vaccines. The big four Pharma companies are in control of the majority of the production of vaccines: Sanofi, Merck, GlaxoSmithKline and Pfizer. With the world wide market valued at $30 billion a year, vaccines are in demand and widely considered a right and often create a healthier public. As many governments are the only suppliers of healthcare in growing countries, they find the need to be able to produce these products within their borders so that they can reach their citizens. New technologies are expanding the capabilities making vaccines affordable, quick and feasible in many of these countries.
