Greg Wiessner's questions to Moderna (MRNA) leadership

Question · Q2 2025

Greg Wiessner, on for Tyler Van Buren, asked for any early indications of demand for COVID-19 vaccines for the upcoming fall and winter season based on customer interactions.

Answer

President Stephen Hoge noted that international demand is stable due to advanced purchase agreements. In the U.S., he described the spring booster campaign as 'solid,' with uptake in the 65+ population down only 1-2%. While these are encouraging signs and customers are preparing, he stated the company remains 'cautiously optimistic' as the true demand picture will emerge in September.
