It’s flu season, which is typically in the fall and winter months, according to the Centers for Disease Control (CDC). Cases of influenza peak between December and February, but the season can extend through May.
Getting vaccinated soon before the flu spreads in communities is recommended for the best protection; however, getting the vaccine anytime during flu season can still protect you against the virus.
Why You Should Get a Flu Vaccine
The flu vaccine significantly reduces the risk of severe illness, hospitalization and complications. It is particularly crucial for protecting vulnerable populations, including:
- Seniors (65+): Vaccination reduces the risk of flu-associated hospitalization by about 40% on average.
- Children: A 2022 study showed that flu vaccination reduced children’s risk of severe life-threatening influenza by 75%.
- Pregnant individuals: Flu shots during pregnancy reduce the risk of flu-associated acute respiratory infection by about 50%.
- People with chronic health conditions: Vaccination is associated with lower rates of some cardiac events among those with heart disease and reduced risk of flu-related worsening of chronic lung diseases.
Even in cases where the vaccine doesn’t prevent infection entirely, it can still significantly reduce the severity of illness. A 2021 study showed that vaccinated adults hospitalized with flu had a 26% lower risk of ICU admission and a 31% lower risk of death than unvaccinated patients. Vaccination was also associated with a 59% reduction in ICU admissions among adults hospitalized with flu.
Furthermore, vaccinating caregivers helps create a protective barrier around those at high risk. In long-term care facilities, vaccination rates among staff and residents substantially reduced the rate and impact of influenza outbreaks.
Herd Immunity and Protecting the Vulnerable
Getting vaccinated doesn’t just protect you; it contributes to community-wide protection. No doubt you’ve heard the term “herd immunity.” Herd immunity occurs when a high percentage of the community is immunized, reducing the opportunity for outbreaks, which is particularly important for protecting those who cannot receive the vaccine, such as infants under six months old and individuals with certain allergies. It’s important to note that egg allergy is no longer considered a contraindication for flu vaccines. People with egg allergies of any severity may receive any age-appropriate influenza vaccine.
A Flu Vaccine Can Prevent Long-Term Effects
Those with severe flu can experience long-term health issues, which vaccination helps prevent. Flu vaccination reduces the risk of flu-related worsening of chronic conditions like COPD. It also helps reduce symptoms that might be confused with those of COVID-19 and decreases the risk of co-infection with influenza and other respiratory viruses, which can lead to more severe outcomes, including long-term respiratory complications.
Widespread vaccination also helps reduce the strain on healthcare resources. During the 2019–2020 flu season, vaccination prevented an estimated 7.5 million influenza illnesses, 3.7 million influenza-associated medical visits, 105,000 influenza-associated hospitalizations, and 6,300 influenza-associated deaths.
The Flu Vaccine is Safe
The flu vaccine has a strong safety record and is continuously scrutinized by health authorities, including the CDC and FDA, which closely monitor the safety of flu vaccines through various surveillance systems. Extensive studies support the safety of flu vaccination, including for pregnant women and their infants.
And it’s a common misconception that the flu vaccine can give you the flu. The flu shot contains inactivated viruses that cannot cause flu. The nasal spray contains weakened viruses that can’t reproduce in warmer body areas, so it also can’t cause flu illness.
Where to Get the Flu Vaccine
There’s no excuse not to get your flu vaccine, considering there are several options to get free or low-cost flu shots. Arizona, for example, has programs to provide free flu shots to uninsured or underinsured residents.
Pima County Health Department offers immunizations for children and adults at no cost to those who are uninsured or underinsured. It provides services at multiple clinic locations throughout the county.
Santa Cruz County Health Services offers FREE flu shots for adults Monday through Thursday from 9:00 AM to 3:00 PM. No appointments are necessary — walk-ins are welcome.
Maricopa County offers free flu shot events to all community members, including those with insurance.
Maricopa County Department of Public Health (MCDPH) operates three childhood immunization clinics for children up to 19 years old, providing immunizations free of charge. They also offer vaccines for uninsured or under-insured adults at their clinics.
Arizona has Sliding Fee Schedule (SFS) clinics throughout the state that provide health services, including vaccinations, to persons without health insurance. The Arizona Department of Health Services (ADHS) provides an interactive map of SFS Clinics map to help residents find nearby clinics.
Adobe Population Health also holds several free vaccine clinics and health fairs in the Nevada and Arizona areas.
