Infectious Diseases & Vaccines
Infectious diseases are medical conditions caused by small organisms, such as bacteria, parasites, fungi or viruses that enter and spread through the body. While many of these organisms reside normally in our bodies, in certain cases they can cause dangerous, and even life-threatening, conditions and diseases.
Epidemiologists, infectious disease specialists, and virologists, as well as other disciplines, study these cases, from the most common to the incredibly rare, to create vaccines and therapeutics to cure affected patients and to stop these diseases from spreading to others. Janssen is dedicated to understanding how these diseases originate, replicate, and affect the body to find solutions that eliminate them.
At Janssen, we understand that there is no time to waste addressing the infectious diseases that affect humanity. We are dedicated to finding novel vaccines and cures for the diseases already out in the world, as well as preventative measures to fight the infections of tomorrow.
We are dedicated to addressing and solving some of the most important unmet medical needs of our time in infectious diseases and vaccines. Driven by our commitment to patients, we develop innovative products, services and healthcare solutions to help people throughout the world.
As new threats emerge, Janssen works rapidly and efficiently to meet them on the field, so far producing 15 treatments for infectious disease. From the 2017 Ebola outbreak, to the ongoing fight against HIV, as well as the COVID-19 pandemic, Janssen has worked tirelessly to constantly improve our understanding of, and treatment for, these diseases.
Moving Fourth towards a better future with HIV
The meaning of living with HIV has changed for the better. But what it means to live well with HIV is a different story, often unconsidered.

COVID-19 stands for COronaVIrus Disease 2019. It is a disease caused by a type of coronavirus, which are viruses that can circulate among animals and that can infect humans: MERS and SARS are also caused by coronaviruses.
Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system, causing patients to be more vulnerable to certain infections and health conditions. When HIV is not treated, it can transition into Acquired Immunodeficiency Syndrome (AIDS), which will lead to more serious illness.
RSV is a type of virus that, like the flu, spreads mostly in annual outbreaks and affects your lungs and breathing passages, with similar symptoms to a cold. There are two different types of RSV, and you can be infected more than once.
Tuberculosis is a bacterial infection that enters through the lungs, but can also travel to different parts of the body, harming important organs such as the kidneys, brain or spine. While the number of cases are declining by 2% each year, active Tuberculosis left untreated is contagious and can spread rapidly.
