When Should I Get The Flu Vaccine? And Which One?

Immunization is a crucial element in public health, dramatically reducing both the incidences and severity of infectious diseases all over the world. Among these, the annual influenza vaccination stands as a vital immunization. The Advisory Committee on Immunization Practices (ACIP) in the United States has updated its guidelines for the seasonal flu immunization for the 2024-2025 season. This review will aim to clarify any updates and highlight key points for both the general public and health professionals.

When Should I Get The Flu Vaccine?

The Centers for Disease Control and Prevention (CDC) recommend receiving the seasonal influenza vaccination during September or October. This period is considered optimal as it precedes the typical onset of the flu season, ensuring that individuals are immunized before exposure to the virus.

Nonetheless, the CDC advises continuation of vaccinations throughout the flu season while the viruses are still in circulation. This extended vaccination period accommodates the variable timing of the flu season and ensures that those who delay vaccination can still receive protection.

It's important to note that while vaccinations during July and August are typically not recommended due to potential reduced protection later in the season, considerations can be made in certain circumstances and for specific groups. For instance, children requiring a two-dose regimen of the flu vaccine should receive the first dose as soon as the vaccine is available, which may be in July or August.

Age-Specific Standards for Vaccine Doses

The dosage and approved ages for different influenza vaccines can vary. For instance, in the case of the Fluzone Quadrivalent, the CDC recommends two doses - either 0.25 mL or 0.5 mL for children aged six months to 35 months. However, a 0.5 mL dose is recommended for individuals aged 3 years and older.

For Afluria Quadrivalent, a standard 0.5ml dose is recommended for individuals aged 3 years and older, while a 0.25ml dose is advised for children aged 6 months through 35 months.
