Simple Process

How A Vaccination Visit Works

Fast, organized and documented — most single-vaccine visits take under 30 minutes.

1

Confirm & Book

Call your preferred clinic to confirm current stock of the vaccine you need, then book online or plan a walk-in visit.

2

Quick Health Review

Our care team reviews your age, health history, allergies, pregnancy status and previous vaccine reactions to confirm the right dose.

3

Vaccination

A trained clinician administers your vaccine, with a brief observation period afterwards for your safety.

4

Records & Reminders

We document your dose and provide official records on request — plus guidance on when any next dose in a series is due.

Why Vaccinate With Us

One Clinic For Your Whole Family’s Immunizations

Keeping a family’s vaccine schedule straight is genuinely hard — different ages, different series, different school and work requirements. Instant Urgent Care makes it manageable by handling everyone under one roof, from a toddler’s catch-up doses to a grandparent’s boosters.

Every dose is administered by trained clinicians and fully documented, so producing records for a new school, an employer, a sports league or an immigration physical takes minutes rather than weeks of chasing paperwork.

Because our clinics also provide urgent care and primary care, vaccination can piggyback on visits you’re already making — add a Tdap booster to your annual physical, or your child’s school vaccines to their sports physical, without a second trip.

Have questions or concerns about a vaccine? Bring them. Our providers give straight, evidence-based answers with no judgment, and a telemedicine visit is a convenient way to talk it through before you come in.

💻
Beyond This Visit

Not Sure Which Vaccines You Need?

Book a telemedicine visit and a provider will review your history, your school, work or travel requirements, and build your exact vaccine plan — then you visit the clinic just once for the doses.

Straight answers about availability, records, insurance and safety.

We provide routine immunizations for adults and children, including seasonal flu shots, Tdap (tetanus, diphtheria, pertussis), MMR, hepatitis A and B, varicella, and school-required catch-up vaccines.

Walk-ins are welcome for most routine vaccines at all three clinics. Booking online or calling ahead is recommended if you need a specific vaccine, multiple doses for family members, or documentation completed the same day.
Most recommended vaccines are covered by insurance as preventive care, often with no copay. Self-pay pricing is available if you are uninsured. Bring your insurance card and we’ll verify your coverage at check-in.
Yes. We document every dose and can provide official records for schools, employers, sports programs and immigration physicals. If you need past records from a visit with us, email support@instantuc.com.
Yes — we routinely handle California school-entry immunization requirements and can complete your child’s vaccines during the same visit as their back-to-school physical or school physical.
We offer pre-travel consultations and many travel-related vaccines. See our dedicated travel vaccinations page, and call ahead so we can confirm which vaccines are in stock for your destination and departure date.
Vaccines used in the United States go through extensive safety testing and continuous monitoring. The most common side effects are mild and short-lived — a sore arm, mild fatigue or low-grade fever for a day or two. Our providers review your health history, allergies and previous reactions before every dose, and you’re welcome to ask questions at any time.
