Why should people get vaccinated against the flu?
The flu can be more than just a bad cold. It can cause serious illness, hospitalization, and even death. Everyone 6 months and older should get a flu vaccine every year, with rare exceptions.
Getting vaccinated can:
- Reduce your risk of getting the flu
- Reduce the risk of serious complications, hospitalization, and death
- Help make illness less severe if you do get the flu
- Help protect people who are more vulnerable to serious flu complications
Flu vaccines are updated each year to help protect against the influenza viruses expected to circulate during the upcoming season, and protection decreases over time. That’s why annual vaccination is important.
Protect yourself. Protect your family. Get your flu vaccine every year.
How do flu vaccines work?
Flu vaccines help your immune system develop protection against influenza viruses. It generally takes about two weeks after vaccination for your body to develop an immune response.
The 2026–2027 seasonal flu vaccines are trivalent, meaning they are designed to protect against three influenza viruses:
- Influenza A (H1N1)
- Influenza A (H3N2)
- Influenza B (Victoria lineage)
Flu viruses change over time, so the vaccine is updated each year to help protect against the influenza viruses expected to circulate during the upcoming flu season.
Getting vaccinated every year is the best way to stay protected against seasonal flu.
What kinds of flu vaccines are available?
This flu season, we offer trivalent flu vaccines for different age groups, including:
- Fluarix® – Adults and children 6 months and older
- Flucelvax® – Adults and children 6 months and older and egg free, for individuals allergic to egg
- Fluad® — Designed to help produce a stronger immune response in adults 65 years and older
- mFlusiva® – Newest influenza vaccine out in the market. It’s particularly notable because it is an mRNA-based flu vaccine, rather than an egg-, cell-, or traditional inactivated-virus vaccine.

Who should get vaccinated this season?
CDC recommends that everyone 6 months and older get a flu vaccine every year, unless there is a medical reason they should not. Flu vaccination is especially important for people who are at higher risk for serious flu complications, including young children, older adults, pregnant people, and people with certain chronic health conditions.
Who should not get a flu vaccine?
Most people can safely receive a flu vaccine. However, some people should talk with their healthcare provider before vaccination, particularly if they:
- Have had a severe allergic reaction to a previous flu vaccine or an ingredient in the vaccine.
- Have a history of Guillain-Barré syndrome (GBS) within 6 weeks of a previous flu vaccination.
- Are currently moderately or severely ill, with or without fever.
People with an egg allergy can receive any age-appropriate flu vaccine.
When should I get vaccinated?
For most people, September and October are ideal times to get vaccinated. However, vaccination should continue throughout the flu season as long as flu viruses are circulating and vaccine is available.
It takes about two weeks after vaccination for your body to develop antibodies that provide protection against influenza.
Where can I get a flu vaccine?
Immunize El Paso offers flu vaccination for children and adults at our clinics and through community outreach events.
Why do I need a flu vaccine every year?
Annual flu vaccination is recommended because protection decreases over time and influenza viruses change. Each year’s vaccine is updated as needed to help protect against the viruses expected to circulate during the upcoming flu season.
Does the flu vaccine work right away?
No. It takes approximately two weeks for your body to develop an immune response after vaccination. Getting vaccinated before flu activity increases in your community gives your body time to build protection.
Can I still get the flu after getting vaccinated?
Yes. Flu vaccination does not guarantee that you will never get influenza. However, vaccination reduces the risk of flu illness and can reduce the severity of illness and the risk of serious complications if you do get sick.
How well the vaccine works can vary from season to season and depends on factors such as a person’s age and health and how closely the viruses circulating in the community match those included in the vaccine.
Can a flu vaccine give me the flu?
No. Flu vaccines cannot cause flu illness. The injectable flu vaccines we provide use inactivated viruses, virus components, or other non-infectious vaccine technologies that cannot cause influenza.
Some people may experience mild, short-lasting side effects after vaccination, such as:
- Soreness, redness, or swelling where the shot was given
- Headache
- Mild fever
- Muscle aches
- Fatigue
These effects are generally mild and go away on their own within a few days.
