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 still helps protect you. Because flu season typically runs from October through March, with peak activity in December through February, it is almost never too late to benefit from the shot.
Key timing facts:
- It takes about 2 weeks after vaccination for your body to build full protection
- Flu vaccines are updated each year to match the most likely circulating strains
- Since protection from last year’s vaccine fades over time, you need a new flu shot every year
Which Flu Vaccine Does CityHealth Offer?
CityHealth gives the standard inactivated flu shot as recommended by the CDC. For patients 65 and older, we offer the high-dose flu vaccine (Fluzone High-Dose or equivalent). This version creates a stronger immune response in older adults. As a result, it is the preferred choice for that age group.
Notably, we do not currently offer the nasal spray (FluMist) flu vaccine. However, the inactivated flu shot is safe and effective for most patients.
Who Should Get a Flu Shot?
The CDC recommends flu vaccination for everyone 6 months of age and older. Although the vaccine helps all age groups, it is especially important for the following groups:
- Adults 65 and older (highest risk for serious problems)
- Pregnant women (and up to 2 weeks postpartum)
- Children under 5 years (especially under 2)
- Anyone with chronic conditions like asthma, COPD, diabetes, or heart disease
- Healthcare workers and other essential workers
- Caregivers or family members of high-risk people
For same-day treatment, visit urgent care in San Leandro at CityHealth — walk-ins are welcome 7 days a week.
Can I Get a Flu Shot and COVID Vaccine at the Same Time?
Yes. The CDC confirms that getting the flu vaccine and COVID-19 vaccine (or booster) at the same visit is safe. Some people feel slightly more arm soreness when two shots are given together. However, this is normal and typically goes away within 1 to 2 days. In other words, there is no need to schedule separate visits for each vaccine.
How Long Does a Flu Shot Take at Urgent Care?
The shot itself takes about 30 seconds. Including check-in and a brief health screening, most patients are in and out in 15 to 20 minutes for a flu shot alone. Besides that, booking online in advance can cut your wait time even more. For this reason, many patients choose to schedule ahead even though walk-ins are always welcome.
Is It Too Late to Get a Flu Shot?
Generally, no. While earlier is better, the flu shot still works as long as flu viruses are going around in your area. Even in December, January, or February — if flu is still active in the Bay Area — visiting CityHealth in San Leandro for your flu shot still makes sense. Meanwhile, our providers can help you decide whether it is the right time for you.
Flu Shot vs. Flu Treatment: Know the Difference
A flu shot prevents influenza before you get sick. However, if you already have flu-like symptoms, a flu shot will not help — that is when you need antiviral treatment like Tamiflu (oseltamivir). In fact, CityHealth offers both options (see our Tamiflu and flu treatment guide):
- Flu vaccine — for prevention, walk-in, covered by most insurance plans
- Flu testing + Tamiflu prescription — for treatment when you are already sick, ideally within 48 hours of first symptoms

Frequently Asked Questions About Flu Shots
Does the flu shot give you the flu?
No. The standard flu shot contains inactivated (killed) virus — it cannot cause influenza. Although some people feel mild side effects like arm soreness, low-grade fever, or fatigue for 1 to 2 days, these are normal and go away quickly.
How effective is the flu vaccine?
Flu vaccine effectiveness varies by year depending on the match between vaccine strains and circulating viruses. In recent years, the flu shot has reduced flu illness risk by about 40 to 60% overall. Even in seasons with lower effectiveness, the vaccine still reduces severity and lowers the risk of hospital stays.
Can I get a flu shot if I am currently sick?
If you have a mild illness without fever, it is generally safe to receive the flu vaccine. However, if you have a moderate to severe illness with fever, it is usually best to wait until you recover. Our clinical staff will check your condition before giving the vaccine.
Is a flu shot safe during pregnancy?
Yes — the flu shot is recommended and considered safe during all trimesters of pregnancy. Because the vaccine passes some antibodies to the baby before birth, it protects both mother and child. Both the CDC and ACOG recommend flu vaccination for all pregnant patients.
