Infectious Diseases & Vaccines

Our goal is to transform people’s lives and to improve public health by fighting infectious diseases worldwide.

To that end we are leveraging solid foundations in science and innovative thinking to bring break-through solutions to key unmet medical needs such as HIV, tuberculosis, hepatitis C and antibiotics for serious infections. We are pioneering unique collaborations to develop a portfolio of solutions, consisting of more effective drugs, preventive treatments, diagnostics and biomarkers to distinguish between various sub-types of a disease.

This remains a priority research and development focus for Janssen because infectious diseases continue to claim and limit lives around the world.

AIDS has killed 25 million people to date, making it one of the most destructive pandemics in history. It is caused by the HIV virus which invades immune system cells, leaving patients open to life-threatening infections. The HIV virus writes itself into a cell’s DNA so that the cell manufactures viruses. HIV is a poorer proof-reader than your own cells and often copies its DNA incorrectly so that the new viruses are quite different from the original. It is because HIV is constantly changing, that it is difficult to treat.

Infectious diseases in Ireland

7,353 people have been diagnosed with HIV in Ireland since the early 1980’s1.

377 people were newly diagnosed with HIV in 20141.

369 were male, 116 were female.1

A bug in the system

One-third of the world’s population is currently infected with the bacteria that cause tuberculosis (TB), and anyone infected has a 10% chance of suffering from TB during their lifetime. People with weakened immune systems are especially at risk of developing this often deadly lung disease. AIDS patients, for example, are ten times more likely to develop TB and often live in developing countries where TB infection is also more prevalent.

Hope for a cure

The first antibiotic to treat TB was discovered 50 years ago, but treatment remains very difficult. Patients need to take four antibiotics continuously for six to nine months, which many find difficult to do. The one-in-ten-million bacteria surviving treatment has time to multiply and spread if no antibiotics are taken. The hunt continues, therefore, for a drug that can treat TB faster and kill the bacteria that survive treatment with existing antibiotics.
