“For our pediatric program, we expect fourth dose data from our ongoing Phase I/II study early next year.”

In context

“ernational markets, Prevnar Adult is the established leader among adult pneumococcal conjugate vaccines. In the U.S., where we did experience a year-over-year decline in the quarter, we are pleased with the overall performance of Prevnar 20. For adults, Prevnar held a market-leading position and grew with the expanded recommendation for adults over 50. In the pediatric market, accounting for about 60% of Prevnar revenues in the U.S., we experienced a delayed timing of government bulk order, which we have seen from time to time. So it's a question of time. I want to provide an update about the next-generation PCV programs. While we previously guided to a Phase III start of our adult 25-valent program in 2025, we are planning to start the study next year if the FDA aligns with our approach. For our pediatric program, we expect fourth dose data from our ongoing Phase I/II study early next year. And pending positive data and regulatory feedback, we have the potential to start both Phase III programs in 2026, streamlining our development approach and aligning with our strategy to provide a single vaccine across age groups. We are committed to maintaining leadership in the PCV space. And as a reminder, our 25-valent vaccine candidate has the potential for improved immunogenicity for serotype 3, which is one of the largest remaining contributors of pneumococcal disease. Serotype 3 alone is estimated to cause approximately 20% of invasive disease in the 65-plus population in the U.S. and EU. Abrysvo also achieved significant international momentum with 75% year-over-year operational growth in the quarter due to expanded access in key markets. In the U.S., we are experiencing the head”
