A Simple Step That Helps Protect Your Whole Season

Influenza is a contagious respiratory illness that can range from mild to severe. A seasonal flu vaccine is updated regularly to help protect against the influenza viruses expected to circulate, which is why vaccination is recommended each year rather than only once.

For most people, September and October are convenient times to get vaccinated before flu activity increases, but getting a flu shot later in the season can still be worthwhile. Because protection takes time to develop, planning ahead helps your immune system prepare before exposure becomes more common.

Instant Urgent Care makes seasonal flu care easy for individuals and families across Silicon Valley. Visit our San Jose, Santa Clara or Sunnyvale clinics for vaccination availability, or come in promptly if symptoms begin. Our providers can evaluate your illness, determine whether testing or prescription treatment is appropriate, and give you clear guidance for recovery.

Feeling Sick?

Flu Evaluation & Treatment When Symptoms Begin

Flu symptoms often appear suddenly and may include fever or chills, cough, sore throat, congestion, body aches, headache and fatigue. Not everyone with influenza develops a fever, and symptoms can overlap with COVID-19 and other respiratory infections.

Early medical evaluation is especially important for people at higher risk of complications or anyone whose symptoms are severe or worsening. Prescription antiviral treatment works best when started early, ideally within the first two days after symptoms begin, although a provider may recommend treatment later in certain situations.

FAQ

Frequently Asked Questions About Flu Shots

Helpful answers about seasonal vaccination, timing and flu treatment.

Annual seasonal flu vaccination is recommended for most people age 6 months and older, with rare exceptions. A healthcare professional can help determine the right vaccine based on age, pregnancy, health conditions, allergies and previous vaccine reactions.
For many people, September and October are good times to receive the seasonal vaccine, ideally by the end of October. Vaccination later in the season can still provide benefit while influenza viruses continue circulating.
It generally takes about two weeks after vaccination for protective antibodies to develop. That is why getting vaccinated before flu activity becomes widespread is helpful.
Injected flu vaccines cannot cause influenza illness. Some people develop temporary soreness, fatigue, headache or a low-grade fever after vaccination as their immune system responds.
Yes. Vaccine protection varies from season to season, and no vaccine prevents every infection. However, vaccination can reduce the chance of illness and may reduce severity and complications if you become infected.
Contact a healthcare provider promptly if you are at higher risk of complications, symptoms are severe or worsening, or you are concerned about your illness. Antiviral treatment is most effective when started early, ideally within 48 hours of symptom onset.
Walk-ins are welcome based on clinic capacity, but seasonal vaccine supply can vary. Please call your preferred San Jose, Santa Clara or Sunnyvale clinic before visiting to confirm current availability.
