Flu Vaccination Guidelines for 2025-2026
Getting a flu shot every season is the most effective way to safeguard against the flu and its serious complications. The timing of your vaccination is also quite important.
The Centers for Disease Control and Prevention (CDC) has updated its influenza vaccine guidelines for the 2025-2026 flu season.
Most recommendations have stayed consistent with the previous 2024-2025 season, including which groups should receive vaccinations, when to get vaccinated, the types of vaccines available, and what precautions to consider.
Typically, flu activity peaks in the U.S. from late fall to early spring. For most people, those infected with the flu tend to recover without severe complications.
However, individuals at higher risk—like older adults, very young children, pregnant individuals, and those with chronic health issues—can experience more severe illness, hospitalization, or even death due to influenza.
When Should You Get a Flu Shot?
Current guidance on when to get the flu vaccination has not changed. September through October is still regarded as the ideal timeframe for receiving the flu shot. Although not recommended, getting vaccinated in July or August might be necessary for some individuals who cannot get the shot during September or October, according to the CDC.
Who Should Receive the Flu Vaccine?
The CDC advises everyone aged six months and older to get a flu vaccine. The vaccine’s effectiveness can vary based on how well the vaccine matches the circulating virus strains. Nevertheless, the CDC emphasizes that getting vaccinated remains the best line of defense against influenza and its potential complications.
What Flu Vaccine Options Are Available?
There are several flu vaccination choices available at pharmacies, doctors’ offices, and health clinics. Trivalent influenza vaccines, which protect against three virus strains, are suitable for all age groups. However, for those over 65, who are more prone to complications, the CDC recommends an enhanced vaccine for better protection. Last year, a nasal spray option known as FluMist was also approved by the FDA.
For individuals with egg allergies, the vaccine can be found in egg-free variants. It’s important to note that people with egg allergies are not at greater risk for severe allergic reactions from egg-based flu vaccines. “Any influenza vaccine that suits the recipient’s age and health status, whether egg-based or non-egg-based, can be given to individuals with egg allergies,” according to the CDC.
