According to the WHO, influenza cases have significantly increased as of early 2026, with the US experiencing a severe season, with estimates of over 15 million cases, 180,000 hospitalizations, and 7,400 deaths. According to the CDC’s estimates published in October 2023, nearly one billion cases of seasonal influenza are reported globally, including around 3-5 million cases with complications. Rising concerns over hospitalization rates, mortality risks among vulnerable populations, and pressure on healthcare infrastructure are encouraging governments and healthcare organizations to strengthen vaccination campaigns. Increased public awareness regarding the importance of annual flu vaccination is also expected to support long-term market growth.
