The Impact of Messenger RNA Vaccines: Exploring Sanofi's Role in Immunization

For over 100 years, we have been protecting the health of millions. But an additional 1.5 million lives could be saved each year with improved vaccination coverage (1).

Did you know?

We are often unaware of the impact that infectious diseases can have on ourselves and our loved ones. They can put us at risk of serious illness, which can lead to death.
