Influenza (Flu) Shots
Don't confuse COVID-19 with the flu
What is the Flu?
Influenza (flu) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness. Serious outcomes of flu infection can result in hospitalization or death. Those at highest risk of serious flu complications include older people, young children, and people with certain health conditions. The best way to prevent flu is by getting vaccinated each year.

Why get the flu shot?
Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children.
Who should get the flu shot?
CDC recommends a yearly flu vaccine for everyone 6 months of age and older with rare exception. Those at highest risk of serious flu complications include older people, young children, and people with certain health conditions should also get the flu shot. Yearly flu vaccine are recommended because a person’s immune protection from vaccination declines over time, so an annual vaccination is needed to get the “optimal” or best protection against the flu. Additionally, flu viruses are constantly changing, so the vaccine composition is reviewed each year and updated as needed based on which influenza viruses are making people sick.
