Getting yearly flu shots is not just about lowering your own risk of illness, hospitalization, and death—it’s also a powerful way to protect those you care about, keeping them safe and healthy.

Are Flu (Influenza) Vaccinations Really Effective?

While flu vaccine effectiveness can vary from year to year, it’s important to note that in some years, the effectiveness is as high as 40% to 60%. This variation is due to factors such as the types of influenza virus that are most prominent during the flu season and how well the vaccine matches those virus types. Rest assured, the vaccine is designed to provide the best possible protection.

The virologists at the Centers for Disease Control and Prevention (CDC) work tirelessly to predict which virus type is likely to be most prevalent in any given year. This proactive approach allows them to distribute the most effective vaccine, significantly reducing the incidence of infection and the severity of any infections that do occur.

During the 2018 to 2019 influenza season, the flu vaccine is estimated to have prevented:

  • 29 million flu illnesses
  • 13 million flu-related medical visits
  • 380,000 flu-related hospitalizations
  • 28,000 flu deaths

Studies have shown that among influenza patients admitted to the hospital, those who were immunized were less likely to be admitted to intensive care units (ICUs).

The Flu Shot for Different Populations

Patients with Heart Disease:

  • Vaccination lowers the risk of heart attacks during flu season.

Patients with Chronic Lung Disease:

  • Vaccination reduces the risk of worsening lung disease.

Diabetic Patients:

  • Vaccination lowers the risk of hospitalization and worsening of diabetes.

Pregnant Women:

  • Vaccination reduces the chance of being hospitalized with the flu by half.
  • Babies of vaccinated mothers are protected against the disease for the first few months after birth before they are eligible for vaccination.

Older Adults:

  • Vaccination lowers the chance of complications from hospitalization and reduces the risk of death.

Flu Shots: The Bottom Line

For optimal protection, the CDC advises all age groups to get their annual influenza vaccination. The ideal time to do so is around September or October each year. However, even if the new year has already begun, the influenza vaccine remains effective, as flu cases often persist until March.
