No insurance? The flu shot is still affordable — ask about our self-pay pricing. Check our insurance and pricing page for details.
When Should You Get a Flu Shot?
The CDC recommends getting your flu vaccine by the end of October each year — before flu season peaks. However, getting vaccinated in November, December, or even later is still beneficial. Flu season typically runs from October through March, with peak activity in December–February in most years.
Key timing facts:
- It takes about 2 weeks after vaccination for your immune system to build protection
- Flu vaccines are updated each year to match the most likely circulating strains
- Getting vaccinated every year is important — protection from last year’s vaccine fades, and strains change
Which Flu Vaccine Does CityHealth Offer?
CityHealth administers the standard inactivated influenza vaccine (flu shot) as recommended by the CDC. For patients 65 and older, we offer the high-dose flu vaccine (Fluzone High-Dose or equivalent), which produces a stronger immune response in older adults and is preferred for patients in that age group.
We do not currently offer the nasal spray (FluMist) flu vaccine.
Who Should Get a Flu Shot?
The CDC recommends flu vaccination for everyone 6 months of age and older. It is especially important for:
For same-day treatment, visit urgent care in San Leandro at CityHealth — walk-ins welcome 7 days a week.
- Adults 65 and older (highest risk for serious complications)
- Pregnant women (and up to 2 weeks postpartum)
- Children under 5 years (especially under 2)
- Anyone with chronic conditions (asthma, COPD, diabetes, heart disease)
- Healthcare workers and other essential workers
- Caregivers or family members of high-risk individuals
Can I Get a Flu Shot and COVID Vaccine at the Same Time?
Yes. The CDC confirms that co-administration of the flu vaccine and COVID-19 vaccine (or booster) is safe. You can receive both at the same visit. Some people experience slightly more arm soreness when two vaccines are given together, but this is normal and typically resolves within 1–2 days.
How Long Does a Flu Shot Take at Urgent Care?
The vaccination itself takes about 30 seconds. Including check-in and a brief health screening, most patients are in and out in 15–20 minutes for a flu shot alone. Booking online in advance can reduce your wait time further.
Is It Too Late to Get a Flu Shot?
Generally, no. While earlier is better, the flu shot offers protection as long as flu viruses are circulating in your community. If it’s December, January, or even February — and flu is still active in the Bay Area — getting vaccinated now still makes sense. Talk to our providers if you’re unsure whether it’s still the right time for you.
Flu Shot vs. Flu Treatment: Know the Difference
A flu shot prevents influenza. But if you’re already sick with flu-like symptoms, a flu shot won’t help — that’s when you need antiviral treatment like Tamiflu (oseltamivir). CityHealth offers both (see our Tamiflu and flu treatment guide):
- Flu vaccine — prevention, walk-in, covered by most insurance
- Flu testing + Tamiflu prescription — treatment when you’re already sick, within 48 hours of symptoms

Frequently Asked Questions
Does the flu shot give you the flu?
No. The standard flu shot contains inactivated (killed) virus — it cannot cause influenza. Some people experience mild side effects like arm soreness, low-grade fever, or fatigue for 1–2 days as their immune system responds to the vaccine. These are normal and temporary.
How effective is the flu vaccine?
Flu vaccine effectiveness varies by year depending on how well the vaccine strains match the circulating viruses. In recent years, the flu shot has reduced flu illness risk by approximately 40–60% in the overall population. Even in seasons with lower effectiveness, the vaccine reduces severity of illness and hospitalization risk.
Can I get a flu shot if I’m currently sick?
If you have a mild illness without fever, it’s generally safe to receive the flu vaccine. If you have a moderate to severe illness with fever, it’s usually recommended to wait until you’ve recovered before getting vaccinated. Our clinical staff will evaluate your condition before administering the vaccine.
Is a flu shot safe during pregnancy?
Yes — the flu shot is recommended and considered safe during all trimesters of pregnancy. Getting vaccinated during pregnancy protects both mother and baby (the vaccine passes some antibodies to the baby before birth). The CDC and ACOG both recommend flu vaccination for pregnant patients.
