General remarks : - In the United States, we also talk about Big Pharma to characterize these largest pharmaceutical laboratories in the world with a projected turnover in 2020 of 489 billion USD for the 10 largest laboratories in the world. - Only 4 countries are represented in the list of the 10 largest pharmaceutical companies in the world: USA (5 times), Switzerland (2 times), United Kingdom (2 times) and France (1 time). - In 2012 it was estimated that the pharmaceutical industry as a whole (i.e. not the top 10 companies in terms of sales) had annual sales of approximately 856 billion USD. - According to some consultants (e.g. EY) the company Takeda Pharmaceutical with 25.8 billion euros in sales in 2019 would also belong to the 10 largest pharmaceutical companies in the world, in 8th position in 2019. Astra-Zeneca would not be in the top 10 in 2019. Vaccines Vaccines sales are mainly concentrated in four companies: Glaxo-Smithkline (GSK), Pfizer, Merck & Co and Sanofi. These four pharmaceutical companies, which belong to Big Pharma, account for more than 80% of global vaccine sales, according to the Handesblatt (German business newspaper) of April 23, 2020. The Handesblatt estimates total annual vaccine sales at $35 billion per year. But the leading English magazine The Economist estimated in its June 6, 2020 edition that annual global vaccine sales were more like $60 billion. The English magazine stated in June 2020 that the Anglo-Swedish laboratory AstraZeneca was seeking to enter the field of vaccines by carrying out research on Covid-19 in particular. Thus BSV can be presented as the catalyst of data recorded on its database, secure, immutable and reducing management costs because BSV centralizes the details of the "production/source" to allow multiple readings at a lower cost (very reduced) from inclusion to extraction the data remains accessible at all times from anywhere on the planet.
