COVID-19 IMPACT

RSV Vaccine Industry Had a Negative Effect Due to Delayed Clinical Trials during the COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

Technological advancements have not completely solved the issues that RSV vaccine trials faced and some of them had to deal with lockdown restrictions and, hence, were delayed. Hospitals were mainly treating pandemic-related patients and thus, could not enroll as many patients for the other trials. Consequently, timelines for data collection, trial participation, and regulatory filings were pushed back, which was a short-term drawback for some vaccine producers.

On the other hand, to a large extent, the COVID-19 pandemic pushed the global vaccine R&D ecosystem to go twice as fast, indirectly making the RSV vaccine market benefactor. The infection's vaccine research and development process set a new precedent in terms of timelines and regulatory approvals. Vaccine manufacturers were quick to pick this up and, thus, brought their RSV vaccine candidates through the process much more smoothly, taking advantage from the fast regulatory pathways and sharing of platforms strategy.

LATEST TRENDS

Dual-Strategy Immunization for Infants to Drive Market Growth

Dual-Strategy Immunization for Infants are vital benefits of RSV vaccine market share. One key tendency is that the market has no other way besides the dual strategy to protect infants, the age group that suffers the highest rates of severe RSV disease. Active Maternal Immunization is the first pillar, which is done through Prefusion F protein-based vaccines (like Pfizer's Abrysvo) given to pregnant women, thereby increasing the mother’s antibodies for the efficient transfer through the placenta to the fetus. The second pillar is Passive Immunization, which consists of long-acting monoclonal antibodies (mAbs) (the ones from Sanofi, Beyfortus/nirsevimab, and Merck's recently approved clesrovimab, for example) that are given to the baby in order to provide immediate, season-long protection.

• Clinical II: Phase II trials open the door for a larger number of participants, who will be further monitored for the vaccine's safety, dosage, and RSV infection prevention effects. Scientists collect more extensively the immunogenicity data to adjust the formulations for the large-scale studies.

• Clinical III: Phase III trials involve large, diverse populations to confirm vaccine effectiveness, monitor adverse reactions, and compare results with placebo or existing treatments. This phase is crucial for obtaining regulatory approval and commercial readiness.

• Preclinical: In the preclinical stage, vaccine candidates undergo laboratory and animal testing to assess safety profiles and immune responses before being tested in humans. This stage helps determine whether a vaccine is viable for human trials.

• Being Developed: Vaccines in the “being developed” stage are under active research, optimization, or awaiting clinical trial approval. This includes candidates using advanced platforms like mRNA, viral vectors, or protein subunits that are expected to enhance protection and durability.

By Application

Based on application, the global market can be categorized into Elderly Vaccine, Infant Vaccine, Others.

• Elderly Vaccine: Elderly RSV vaccines are designed to protect older adults who face a higher risk of severe respiratory complications due to weakened immunity. These vaccines aim to boost immune response and reduce hospitalizations linked to RSV infections in aging populations.

• Infant Vaccine: Infant RSV vaccines target newborns and young children, who are among the most vulnerable to RSV-related bronchiolitis and pneumonia. They are often administered through maternal immunization or pediatric formulations to ensure early-life protection.

• Others: This category includes vaccines developed for special populations such as pregnant women, immunocompromised individuals, or those with chronic respiratory conditions. These vaccines are tailored to provide targeted immunity and reduce RSV transmission within high-risk groups.

MARKET DYNAMICS

Driving Factors
