US Government Investment of Flu Vaccines
As early as next year, more modern and more effective vaccines will hit the market. This is thanks to investments by the U.S. government and pharmaceutical companies. Even bigger scientific advances are also expected in the next decade, including a "universal" flu vaccine given every five to 10 years that would fight many strains of a virus. In the last 12 months, the U.S. Food and Drug Administration has approved two new seasonal flu vaccines that protect against four predominant strains of flu instead of three. Flu vaccines have not been high-revenue generators for major pharmaceutical companies compared with big-selling drugs for diabetes, heart disease, rheumatoid arthritis and cancer.
