Manufacturing vaccines is a complex journey

Vaccines manufacturing is a biological process where a very high level of expertise is required. We need to continually adapt production process to satisfy evolving regulatory demand which varies country by country.
In addition, the production process is under even greater pressure as demand for certain vaccines grows, such as pediatric combination vaccines and as demand increases from the global public health community to investigate new and emerging threats.

Vaccines have to be held to the highest standard of safety. Prior to their approval by the health authorities, our vaccines are tested extensively to ensure they are effective and safe. Once in use, they are also continually monitored for safety through our pharmacovigilance system.
Sanofi Pasteur develops, manufactures and distributes vaccines that respect regulatory requirements and our company’s values. We are committed to making the safest and most effective vaccines possible available everywhere in the world.
