My journey as a scientist was born out of a lifelong fascination with bacteria, their biology, and their biochemistry as the smallest and earliest forms of life on earth. Today, we are faced with an extraordinary situation in which pathogenic bacteria, parasites and fungi are becoming increasingly resistant to antimicrobials, threatening to send us back to a time when we were unable to easily treat infections like pneumonia or tuberculosis.
Life-threatening diseases such as bacteremia/sepsis, pneumonia, diarrhea and tuberculosis cause at least 15 million fatalities worldwide, annually. The alarming truth is that antimicrobial resistant (AMR) infections are present in every country, and are responsible for at least 700,000 of those fatalities every year. By 2050, it is predicted that AMR-related deaths could rise to 10 million annually, worldwide. 1-5
As we observe World Immunization Week, we see the burden of these diseases and the growing threat of AMR, and recognize the crucial need to develop preventive vaccines, particularly for vulnerable populations such as older adults. Vaccines will offer a new tool in the fight against AMR, adding a layer of protection on top of new antibiotics, increased awareness of the value of existing antibiotics, and implementation of better stewardship for the use of antibiotics.
In industrialized countries, there is an increased demand among aging populations for complex invasive medical procedures such as hip or knee replacements – procedures which can sometimes lead to a life threatening or disabling infection, often caused by Staphylococcus aureus (S. aureus). Older age is one of the risk factors for invasive extra-intestinal Pathogenic E. coli (ExPEC) disease. A common source for this type of infection are urinary tract infections (UTI). It is unnerving to consider that when either yourself or a loved one undergoes an operation, they could contract an infection that could cause surgical-site infections, invasive life-threatening bacteremia (presence of bacteria in the blood) or other serious life-changing complications.
European and U.S. studies have shown that extended spectrum beta-lactamase-producing E.coli (ESBL) and methicillin/multi-resistant S. aureus (MRSA) are the dominant bacteria in these regions.2,6,7 Meanwhile, countries like China, India and Russia are particularly impacted by drug-resistant tuberculosis (DR-TB), which is another leading contributor to AMR-related deaths globally.8
Janssen recognizes that AMR is a complex problem that is driven by many interconnected factors, and addressing it will require holistic solutions. In my role at Janssen, I work at the forefront of bacterial vaccines development for ExPEC and S. aureus, both of which are prone to AMR.2 The reason for our vaccine research prioritization is clear when you consider that there are more antimicrobial resistant ExPEC and S. aureus-related fatalities than all other bacterial infection-related deaths combined.2,6,7
AMR is one of the defining scientific, health and economic challenges of our time. Only through research, innovation and coordinated action across sectors will we be able to minimize the emergence and spread of AMR. At Janssen, we are taking action to be a part of the solution to AMR.
