Basic information

Flu season occurs annually from fall to spring, marked by the widespread transmission of influenza viruses. 

Receiving a flu shot is the most effective way to protect against the flu, significantly reducing the risk of infection and its complications. The vaccine is updated yearly to match circulating strains and is recommended for everyone over six months old, particularly vulnerable groups like the elderly, young children, and those with chronic health conditions. Besides individual protection, widespread vaccination helps achieve community immunity, reducing the overall prevalence of the flu and easing the burden on healthcare systems.
