Sanofi's Beyfortus Boosts Sales Amid Merck Competition and Expanded RSV Vaccine Production

Sanofi's Beyfortus has experienced significant sales growth, fortifying its market position amid competition from Merck's RSV antibody, clesrovimab. In the third quarter, Beyfortus achieved sales of €645 million, marking a 382% increase from the previous year, contributing to Sanofi's overall 15.7% sales growth[1][2]. This growth is supported by an expansion in production capacity by Sanofi and its partner AstraZeneca, to address earlier supply shortages driven by unexpected demand[2]. Despite Merck's imminent market entry, Sanofi remains optimistic, bolstered by Beyfortus's past efficacy and robust sales trajectory[1].
