CSL Seqirus Shares Important Insights on Flu Vaccine Efficacy

CSL Seqirus Shares Findings at OPTIONS XII Conference

CSL Seqirus recently made a substantial impact at the OPTIONS XII Conference, showcasing real-world evidence (RWE) studies that highlight the effectiveness of both cell-based and adjuvanted influenza vaccines. These studies aim to reinforce the importance of influenza vaccinations, particularly as the flu season approaches.

Evidence of Improved Vaccine Effectiveness

Multiple RWE studies presented at the conference have illustrated a notable improvement in relative vaccine effectiveness (rVE) of cell-based vaccines compared to the traditional egg-based vaccines. This improvement was observed across various age groups, including vulnerable populations such as toddlers as young as six months old.

Highlights from Recent Studies

One of the key findings presented indicates that during the 2023/24 season, cell-based vaccines had an outstanding effectiveness rate of 88% against medically attended, lab-confirmed influenza in children aged six months to three years when compared to unvaccinated individuals. Such statistics underscore the critical role these vaccines play in safeguarding the health of younger populations.

CSL Seqirus passionately believes in the importance of RWE studies as they complement traditional randomized controlled trials (RCTs). By collecting real-world data, they contribute significantly to the ongoing assessment of influenza vaccine effectiveness.

The Role of CSL Seqirus in Public Health

Gregg Sylvester, Chief Health Officer at CSL Seqirus, emphasized the organization's commitment to generating robust real-world evidence regarding vaccine effectiveness. He stated, "Our studies and presentations at OPTIONS XII reflect our dedication to helping protect individuals of all ages against influenza and its serious health complications."

Among the significant RWE studies discussed was a comprehensive analysis of the 2022/23 influenza season in the US. This study revealed that cell-based quadrivalent vaccines were more effective in preventing outpatient test-confirmed influenza compared to egg-based vaccines among individuals aged six months to 64 years. Results showed an improved rVE that indicates cell-based options should be prioritized.

Broader Implications of Vaccine Effectiveness

Another recent study also demonstrated that the cell culture-based inactivated influenza vaccine (ccIIV4) yielded impressive results against laboratory-confirmed cases of influenza. The findings pointed out that effectiveness was highest among the youngest age group, reinforcing the idea that targeting this demographic is essential for increasing public health safety.

Comparative Effectiveness among Different Vaccines

Additional insights from the RWE presented included finding of relatively high effectiveness of MF59-adjuvanted vaccines when compared to high-dose quadrivalent vaccines. The comparative data is crucial for healthcare professionals and patients alike, as it showcases the options available for combating influenza.
