CSL Seqirus is on the front line of influenza protection, helping guard against costly and life-threatening epidemics and pandemics. Vaccination is the most effective way to prevent influenza1.
More dangerous than you might think
It's estimated that about 1 in 18 children, 1 in 38 elderly and 1 in 45 adults3 who get influenza-like illnesses will seek medical attention, so the disease could be more widespread than we know.
Death from influenza is much more common among the elderly and the very young, but all ages are at risk for serious complications such as pneumonia, myocarditis, and inflammation of the brain or meninges.2
Our bodies and the influenza virus are in a never-ending race. As our immune system evolves to avoid infection, the virus adapts to evade our immune system. This is why we need new influenza vaccines each influenza season - and why we are always working to stay ahead of the mutating virus. The new virus strains generally appear first in Southeast Asia then travel to the rest of the world. Influenza spreads best when temperatures and humidity are low, so the flu season coincides with the winter months in all different parts of the globe.
