Note on Biologic Patents

Matching patents to biologic drugs is far more complicated than for small-molecule drugs.

DrugPatentWatch employs three methods to identify biologic patents:

1. Brand-side disclosures in response to biosimilar applications

These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

2. DrugPatentWatch analysis and brand-side disclosures

These patents were identified from searching drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

3. Patents from broad patent text search

For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

Market Dynamics and Financial Trajectory for the Respiratory Syncytial Virus (RSV) Vaccine

Last updated: August 2, 2025

---

Introduction

Respiratory Syncytial Virus (RSV) remains a leading cause of lower respiratory tract infections globally among infants, the elderly, and immunocompromised populations. Despite longstanding awareness, effective preventive measures have been limited until recent advances in vaccine development. The global RSV vaccine market is poised for rapid growth, driven by scientific innovation, demographic shifts, and strategic shifts in healthcare priorities. This analysis explores the key market dynamics and the financial trajectory shaping the future of RSV vaccines.

---

Epidemiological Drivers and Market Demand

RSV accounts for approximately 33 million acute respiratory infections annually, resulting in an estimated 199,000 deaths—predominantly among children under five and adults over 65 [1]. The epidemiological burden underscores substantial unmet medical needs, particularly in developing regions with limited healthcare infrastructure.

The seasonal nature of RSV infections, in combination with increasing susceptibility in vulnerable groups, fuels sustained demand for effective prophylactic vaccines. The expanding elderly population globally, projected to reach 1.5 billion by 2050, amplifies the need for vaccines targeting at-risk adults [2].

---

Scientific and Technological Innovations

Recent breakthroughs have revolutionized RSV vaccine development, transitioning from passive immunizations like palivizumab—expensive monoclonal antibody therapies—to active, prophylactic vaccines. Leading candidates employ various platforms:

• Protein subunit vaccines (e.g., Novavax’s RSV F subunit vaccine) promising high efficacy.
• Vectored and mRNA vaccines, leveraging novel technology for rapid deployment.
• Nanoparticle-based formulations, aiming for enhanced immunogenicity.

The approval of Pfizer’s Abrysvo (bavtelovimab) application in 2023, and regulatory reviews by the FDA and EMA, signal regulatory confidence in these innovations [3].

---

Regulatory Landscape and Market Accessibility

Regulatory agencies are facilitating expedited pathways for RSV vaccines, especially under pandemic or urgent health contexts. The FDA granted Breakthrough Therapy Designation to several candidates, accelerating clinical review processes. Government initiatives, such as the US CDC’s Immunization Program and WHO’s global vaccine strategy, are prioritizing RSV vaccine integration into immunization schedules.

Pricing strategies and reimbursement policies significantly influence market penetration, especially in countries with varied healthcare budgets. The high cost of vaccine development (estimated between $1 billion and $2 billion) underscores the financial stakes involved for manufacturers navigating approval, manufacturing scale-up, and market entry.

---

Competitive Landscape and Key Players

The RSV vaccine market features a handful of dominant players:

• Pfizer: Leading with Abrysvo, targeting pregnant women and older adults.
• GSK: Developing vaccines like ResVax and pursuing early-stage candidates.
• Novavax: Advancing protein subunit vaccines with promising Phase 3 data.
• Johnson & Johnson and other biotech firms are also exploring innovative platforms.

Strategic alliances, licensing agreements, and public-private partnerships are prevalent, aiming to streamline development and distribution.
