Manufacturing vaccines is a complex journey

Manufacturing vaccines is a complex journey. It takes between 6 to 36 months to produce, package and deliver high quality vaccines to those who need them. It includes testing each batch of vaccine at every step of its journey, and repeat quality control of batches by different authorities around the world.

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.

Journey of vaccine

Vaccine research is long, complex and costly. Its development cycle and production are specific

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.

Making vaccines

Sanofi Pasteur top priority is to provide vaccines to protect people’s health and we do everything we can to quickly resolve any supply issues that delay us in delivering on this priority. We believe in a world in which no one suffers or dies from a vaccine preventable disease. In order to achieve that goal, we have implemented an ongoing investment program in building internal production capabilities.
