Flu Information – Seasonal Flu

The timing and length of the flu season varies from year to year. Typically, flu activity increases in October and peaks between December to February and can last until the end of May.

The Centers for Disease Control and Prevention (CDC) recommends the flu vaccine as the first and most important step in protecting against the flu. It is the best way to reduce the chances that you will get seasonal flu and lessen the chance that you will spread it to others. When more people are vaccinated less flu can spread through the community. Flu vaccination reduces flu- related illnesses, doctor’s visits and missed days of work or school from the flu. Vaccination to the flu can also decrease or prevent flu-related hospitalizations.

The standard flu vaccine is recommended for:

  • Everyone 6 months of age and older
  • Pregnant women
  • Patients with asthma
  • Anyone with a weakened immune system (i.e. if you are on long-term steroids)
  • Patients with egg allergy can safely receive the flu vaccine
