The flu vaccine is our best defense against influenza, a contagious respiratory virus that causes millions of illnesses and thousands of deaths in the US each year. Despite being only 40-60% effective, the vaccine significantly reduces hospitalizations, outpatient visits, and deaths while protecting vulnerable populations who cannot be vaccinated.

• Influenza causes 9-41 million illnesses, 140,000-960,000 hospitalizations, and 12,000-80,000 deaths annually in the US
• Everyone aged six months and older should receive the flu vaccine yearly
• The vaccine must be updated annually because the flu virus changes each year
• Getting vaccinated helps protect vulnerable populations like infants and immunocompromised individuals
• Common misconception that the vaccine causes flu is false – it cannot give you the flu
• Only 40-46% of Americans get the flu vaccine annually despite its proven benefits
• The best time to get vaccinated is before flu season begins, but getting it later still helps
• Flu vaccination reduces strain on hospitals during peak seasons

Go get your flu shot today! It's the best way to protect yourself, your loved ones, and your neighbors
