Sanofi Pasteur is the vaccines division of the French multinational pharmaceutical company Sanofi. Sanofi Pasteur is the largest company in the world devoted entirely to vaccines. It is one of four global producers of the yellow fever vaccine.[2]


Main article: Sanofi Biogenius Canada

Since 1992, Sanofi Pasteur has sponsored Sanofi Biogenius Canada (SBC), a national, biotechnology-focused science competition for Canadian high school and CEGEP students. Those selected for the SBC work with local mentors, giving students hands-on research experience in a professional lab setting. Participants compile their results and present their findings at regional competitions. Cash prizes are awarded and regional winners advance to the National stage, where they vie for the top spot and the chance to compete in the International BioGENEius Challenge, held at the prestigious BIO International Convention – the largest biotechnology event in the world.

In 2004, Aventis merged with and into Sanofi. The new Sanofi-Aventis Group became the world's 3rd largest pharmaceutical company. Aventis Pasteur, the vaccine division of Sanofi-Aventis Group,[3][4] changed its name to Sanofi Pasteur.[5] In 2014, Sanofi Pasteur stopped producing its effective Fav-Afrique antivenom because competition from cheaper though less powerful competitors made it unprofitable.[6] Doctors Without Borders said that it would take two years to develop a similar antivenom, and that existing stocks would run out in June 2016.[6]

Further information: BCG vaccine § Supply shortage

In the fall of 2011 the Sanofi Pasteur plant flooded, causing problems with mold.[7] The facility, located in Toronto, Ontario, Canada, produced BCG vaccine products made with the Glaxo 1077 strain,[8] such as a tuberculosis vaccine and ImmuCYST, a BCG immunotherapeutic and bladder cancer drug. By April 2012 the FDA had found dozens of documented problems with sterility at the plant including mold, nesting birds and rusted electrical conduits, as well as numerous procedural safety issues and violations.[7] The resulting closure of the plant for over two years resulted in shortages of bladder cancer and tuberculosis vaccines.[9] On October 29, 2014 Health Canada gave the permission for Sanofi to resume production of BCG.[10]

Main article: Dengvaxia controversy

The Philippine Department of Health began in 2016 a programme in three regions to vaccinate schoolchildren against dengue fever, using Dengvaxia supplied by Sanofi Pasteur. On 29 November 2017, Sanofi issued a caution stating that new analysis had shown that those vaccinated who had not previously been infected with dengue ran a greater risk of infection causing severe symptoms. On 1 December 2017, the Philippine DOH placed the programme on hold, pending review. Over 700,000 people had received at least one vaccination at that point.[11][12] Since the announcement by Sanofi, at least 62 children have died, allegedly after receiving a vaccination. The victims' parents blamed the dengue vaccine for the deaths of their children.[13]

In July 2020, Sanofi Pasteur announced that it would begin phase three testing of a COVID-19 vaccine in several countries, including Mexico, and that the cost would be US $7 to $10 per dose.[14] If data are positive, a global phase 3 study could start in Q2 2021. If the vaccine meets clinical requirements on safety and effectiveness, approved by regulatory authorities, a vaccine can expected in the fourth quarter of 2021.[15] One of the vaccines ordered by the Netherlands for the mass anti-coronavirus vaccination programme in 2021 seems not to work well in elderly people and the development of the vaccine will face delays.[16]

In 2021, Sanofi Toronto announced it was seeking to start a new Biosafety level 3 laboratory.[17]
