Respiratory Syncytial Virus (RSV) Vaccine Market Summary

The Respiratory Syncytial Virus (RSV) vaccine market, with a primary focus on the United States, stands as a cornerstone in preventive medicine for respiratory infections, addressing one of the leading causes of acute lower respiratory tract disease in vulnerable populations. RSV, a paramyxovirus, infects nearly all children by age two, resulting in over 3.6 million hospitalizations and approximately 100,000 deaths annually in children under five worldwide, with 97% of fatalities in low- and middle-income countries due to limited supportive care. In the U.S., it prompts medical attention for more than two million children under five each year, including up to 80,000 hospitalizations, while imposing a heavy toll on older adults, causing up to 160,000 hospitalizations and 10,000 deaths in those aged 65 and above. The market features a dual approach: maternal vaccines and long-acting monoclonal antibodies for infant protection via passive immunity transfer, and direct vaccines for adults emphasizing glycoprotein F stabilization to elicit neutralizing antibodies and T-cell responses. Key attributes include single-dose regimens for adults, booster considerations for high-risk groups, and integration with seasonal flu campaigns to enhance compliance. Innovation centers on multivalent formulations combining RSV with influenza or COVID-19 antigens, alongside adjuvanted designs boosting durability in immunocompromised individuals. Challenges encompass variable efficacy against subgroups A and B, potential Guillain-Barré syndrome risks highlighted in post-marketing surveillance, and supply chain demands for cold-chain integrity during peak winter seasons. The U.S. market benefits from CDC advisory committee recommendations prioritizing high-burden groups, fostering rapid uptake through pharmacy networks and Medicare Part D coverage. By 2025, the U.S. RSV vaccine market is estimated to be valued between USD 1.3 billion and USD 2.0 billion, with a projected compound annual growth rate (CAGR) of 2.5% to 4.5% through 2030. This tempered expansion mirrors steady adult immunization rates amid evolving guidelines, expanded indications for younger at-risk adults, and public health campaigns countering hesitancy, though constrained by seasonal demand fluctuations and competition among three approved adult vaccines.
