Abstract
Introduction
This study aimed to estimate and compare the lifetime clinical and economic burden of invasive pneumococcal diseases (IPD) attributable to the serotypes contained in a new 21-valent pneumococcal conjugate vaccine (V116) vs. the 20-valent pneumococcal conjugate vaccine (PCV20) among adults aged 18 years and above in the USA.
Methods
A state-transition Markov model was used to track IPD cases and deaths as well as the associated direct medical costs (in 2023 US dollars) from a US healthcare payer perspective at 3% annual discount rate. The results were summarized for V116, PCV20, and eight unique serotypes contained in V116. A sensitivity analysis was conducted to determine the most influential inputs on the overall total direct lifetime cost.
Results
For the total population of US adults aged 18 years and above in 2021 (approx. 258 million residents), the estimated lifetime numbers of cases of IPD, post-meningitis sequelae (PMS), and IPD-related deaths attributable to the serotypes contained in V116 were approximately 1.4 million, 17,608, and 186,200, respectively, with a total discounted lifetime direct cost of $32.6 billion. A substantial proportion (approx. 31%) of those were attributable to the unique eight serotypes. The corresponding estimates for PCV20 were approximately 35% lower—934,000, 11,500, and 120,000, respectively—with a total discounted direct lifetime cost of $21.9 billion.
Conclusion
These results show that V116 serotypes (compared to PCV20) are associated with substantially higher clinical and economic burden of IPD. The addition of V116 to vaccination recommendations can help to reduce the residual burden of IPD in US adults.
期刊介绍:
Infectious Diseases and Therapy is an international, open access, peer-reviewed, rapid publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of infectious disease therapies and interventions, including vaccines and devices. Studies relating to diagnostic products and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to, bacterial and fungal infections, viral infections (including HIV/AIDS and hepatitis), parasitological diseases, tuberculosis and other mycobacterial diseases, vaccinations and other interventions, and drug-resistance, chronic infections, epidemiology and tropical, emergent, pediatric, dermal and sexually-transmitted diseases.
