Many of us have felt the consequences of infectious diseases, whether personally, through a family member or as a community. Diseases such as HIV, ebola, hepatitis B, RSV and COVID-19 are part of our reality – but at Janssen we are committed to halting the spread of these diseases and reducing the burdens they place on you, your loved ones and global health systems.
Dedicated to fighting infectious diseases with the broadest impact on human health
We have an ambitious goal: to ensure a future where we can prevent the spread of infectious diseases and eliminate the burden they place on global health.
Infectious diseases are one of the greatest threats to mankind – evolving, spreading and disproportionately affecting the most vulnerable. Of the top 10 causes of death worldwide, 3 are infectious diseases. 
This has never been more apparent than with the COVID-19 pandemic, which caused a major global public health crisis, affecting billions of people, directly or indirectly, worldwide. All of these factors show that the world urgently needs solutions to help combat infectious diseases.
Our efforts are focused on tackling the most complex infectious diseases, finding the right paths of intervention and making sure they reach those in need. We have an ambitious goal — to ensure a future where we can prevent the spread of infectious diseases and eliminate the burden they place on global health.
"We want to reduce the burden and serious consequences of infectious diseases and, by doing so, change the trajectory of human health. We will do this through an unwavering commitment to the continual advancement of our science."
Janssen EMEA Medical Affairs Director, Vaccines
We envision a world where:
The world is no longer threatened by COVID-19 and we are better prepared to respond quickly to potential future pandemics.
Medicines and vaccines guard people from the dangers of infectious diseases during all stages of life, from infancy to adolescence through adulthood.
A functional cure* has eliminated patients’ life-long struggle with chronic hepatitis B.
Preventive and therapeutic options could help to end the HIV epidemic.
The most vulnerable are protected against the threat of respiratory and bacterial infections.
*N.B. A functional cure for chronic hepatitis B is defined as sustained, loss of hepatitis B surface antigen (HBsAg) with or without seroconversion to hepatitis B surface antibody.
