Burden of disease
Pneumococcal pneumonia and IPD are a serious risk for adult patients1-4
Pneumococcal pneumonia is the most common clinical manifestation of pneumococcal disease in adults. It leads to 150,000 US hospitalizations annually and is estimated to account for 10 to 30% of all adult community-acquired pneumonia (CAP) cases in the US.5 CAP occurs when someone develops pneumonia outside of a hospital.6
Pneumococcal pneumonia leads to 150,000 hospitalizations annually in the US5
The same bacteria that cause pneumococcal pneumonia, Streptococcus pneumoniae, can invade normally sterile sites in the body, such as the blood or cerebrospinal fluid. When this occurs, it is referred to as IPD. IPD is a serious illness that can lead to hospitalization, complications including bacteremia and meningitis, and sometimes death.5
In the US, IPD is ~4x more likely to lead to death in adults over the age of 65, compared to those aged 18-647,a
Annual rate of IPD in US adults, 2018-20217,a
The serotypes that cause the majority of IPD cases in US adults have shifted over time1
Nearly half of all IPD cases in adults 65+
are caused by serotypes not included in any other PCV approved for adults1,8,b
These values are based on CDC epidemiologic data and do not reflect the efficacy of any pneumococcal vaccines.9
Adults may benefit from a PCV designed to cover serotypes responsible for the most adult IPD cases10
