Denton County Health Department: Free Vaccine & Screening Programs (2026 Guide)

Putting off a vaccine or a health screening because you're not sure what it'll cost? You're far from the only one. Denton County Public Health (DCPH) runs several clinical programs for residents who don't have good insurance, or none at all. Some of it really is free. Some of it isn't, even though it gets marketed that way online. This guide sorts out which is which, so you walk into your appointment knowing exactly what to expect.

We'll cover children's and adult vaccines, travel shots, STI/HIV and TB testing, primary care, and women's health services, plus the two clinic locations and what to bring. We'll also flag the one insurance rule that catches more Denton County parents off guard than anything else on this page.

Quick Answer

Question	Answer
Are DCPH vaccines really free?	Not automatically. Qualifying uninsured or underinsured patients are typically charged $10 per vaccine, plus 3% for card payments. Medicaid/CHIP patients usually pay nothing.
Who can use these programs?	Uninsured children (TVFC) and adults 19+ (Adult Safety Net) for vaccines; STI/HIV screening is open to anyone.
What does screening cost?	STI/HIV screening runs a $30 office visit fee; TB skin testing is $20. Treatment after a positive STI result is free.
Do I need an appointment?	Yes, for almost everything. A small number of walk-in slots exist, but they go first-come, first-served.

What Does Denton County Public Health Actually Offer?

Think of DCPH less like a walk-in vaccine shop and more like a public safety-net garage. Your regular doctor is the mechanic who already knows your history. DCPH exists for the people who don't have that — no insurance, a plan that doesn't stretch far enough, or a specific service that's hard to find nearby. It's not trying to replace your pediatrician. It's there so a lack of coverage never becomes the reason someone skips care entirely.

The county's clinical services go well beyond immunizations. Current offerings include vaccines, primary care, STI/HIV testing, tuberculosis services, dental services, WIC, and women's health care. Eligibility rules aren't the same across all of them — some depend on age and insurance status, others on income, residency, and household size. Being uninsured doesn't automatically make a service free. It also doesn't automatically shut you out.

Service	Who May Qualify	Cost / Notes
Children's Vaccines (TVFC)	Children 18 and younger who meet TVFC categories	$10 per vaccine for uninsured/underinsured patients, plus 3% card fee
Adult Vaccines (Adult Safety Net)	Uninsured adults 19 and older	$10 per vaccine, plus 3% card fee
STI / HIV Screening	Anyone	$30 office visit fee; treatment is free if you test positive
Primary Care	Uninsured Denton County residents (financial screening required); CHIP/Medicaid patients with DCPH as their provider	Co-pays start at $0 and scale with income; no co-pay for CHIP or Children's Medicaid
TB Services	Anyone needing testing, counseling, or treatment for a reported case	$20 skin test; must return within 48–72 hours for reading

💡 EasySmart Tip for Denton County Residents: Don't assume "public health clinic" means everything is free. Ask about the exact program, your insurance status, and any fee before your appointment. One phone call can prevent a surprise charge at the front desk.

Are Denton County Vaccines Actually Free?

Short answer: usually not, though they're still a bargain compared to full retail price. DCPH provides vaccines through programs built to help people who'd otherwise struggle to get immunized — but that's not the same thing as a blanket free-vaccine policy for every resident.

Children and the Texas Vaccines for Children (TVFC) Program

Kids 18 and younger may qualify for TVFC if they fall into one of these categories.

Enrolled in Children's Medicaid or CHIP
Uninsured, with no health coverage at all
American Indian or Alaska Native
Underinsured — private plan doesn't cover vaccines, only covers some, or has hit a coverage cap

"Underinsured" trips people up the most. A child can have private insurance and still qualify if that plan doesn't cover vaccines, only covers certain ones, or caps how much it'll pay per year. Uninsured or underinsured families should expect a $10 charge per vaccine, plus 3% if paying by card. Medicaid and CHIP typically cover the cost directly, so most families in those programs don't pay the per-vaccine fee.

Adults and the Adult Safety Net Program

Adults 19 and up can get routine immunizations through the Texas Adult Safety Net program if they're uninsured. Some Texas Medicaid enrollees qualify for select vaccines too, though Adult Safety Net doesn't stock everything on the adult schedule. Same pricing applies here: $10 per vaccine, 3% extra by card. Bring a valid ID, your Medicaid card if you have one, and whatever immunization record you can dig up — an old school form, a military record, or a past employer's file all work.

Traveling Internationally? A Couple of Travel Vaccines Are Available

DCPH also carries some common travel vaccines, priced separately from the assistance programs above since insurance isn't billed either way.

Travel Vaccine	Cost
Hepatitis A	$65
Typhoid	$170

Not every travel vaccine is stocked at every visit. Call ahead and confirm availability before you book your trip around it, and check the CDC's destination guidance so you know exactly what your itinerary actually requires.

The Insurance Rule That Trips Up the Most Parents

Here's where most families get caught off guard. If your child has private insurance that covers vaccines, and that coverage hasn't been exhausted, they generally don't qualify for TVFC — even if you'd rather use DCPH for convenience or cost. Insured kids with active vaccine coverage are expected to see their regular provider instead.

There's a reason for the rule. TVFC funding is earmarked specifically for children who'd otherwise go without vaccines. Handing that supply to kids who already have coverage means less available for the families who have no other option. If you're unsure whether your plan counts as underinsured, call and ask before your visit — don't guess, and don't assume either way.

⚠️ Important Note: DCPH does not bill private health insurance for any service on this page. Even a child who qualifies as underinsured for one vaccine still pays out of pocket at the visit. You settle up with your insurer separately, on your own, if that applies to your situation.

STI, HIV, and Tuberculosis Screening

DCPH's screening services matter even if you feel perfectly healthy, since several of these conditions don't show early symptoms.

STI and HIV Testing

Confidential screening for gonorrhea, chlamydia, syphilis, and HIV is available to anyone at both Denton and Lewisville clinics. It's a $30 office visit fee, by appointment, and results usually take one to two weeks.

If a result comes back positive, treatment is provided at no cost. DCPH doesn't manage long-term HIV care on-site, but staff will refer you to a treatment provider. If you searched for "free STI testing near me" and landed here, this is the honest version: affordable, confidential, and low-cost — not free at the door.

Tuberculosis Testing and Treatment

DCPH offers TB testing, counseling, and treatment for reported positive cases in the county. A skin test runs $20, and there's a catch worth planning around: you have to physically return within 48 to 72 hours so staff can read the result in person.

Miss that window, and you're starting over with a new test. If a doctor or public health official has told you to get tested, call DCPH directly so they can walk you through next steps.

Primary Care for Uninsured Residents

Beyond vaccines and screenings, DCPH runs a Primary Health Care Program for diagnosing and treating minor illness and injury in both adults and children. If your child has CHIP or Children's Medicaid with DCPH listed as the primary care provider, you can call to schedule directly — no co-pay applies.

If you're uninsured and live in Denton County, you'll need a financial and medical screening first. Eligibility is based on income, resources, residency, and household composition, and co-pays start at $0, scaling up depending on your income and enrollment plan.

This program isn't urgent or emergency care. It's built for routine, non-emergency visits — a persistent cough, a minor injury, an infection that needs a prescription. Think of it as a primary care safety net, not a substitute for the ER.

Women's Health Services

DCPH's Women's Health Program covers well-woman exams, breast and cervical cancer screening, and checks for cholesterol, diabetes, blood pressure, and postpartum depression, alongside family planning and birth control.

If you're enrolled in CHIP-Perinatal, Medicaid for Pregnant Women, Healthy Texas Women, or the Family Planning Program, you likely qualify automatically as long as DCPH is your listed provider. Without that coverage, expect a financial and medical screening appointment first. Co-pays only apply within the Family Planning Program, starting at $0 and scaling with income.

One thing worth remembering: qualifying for one DCPH program doesn't automatically qualify you for another. Vaccines, primary care, and women's health all run on separate eligibility rules, so don't assume approval for one means approval for all.

Two Clinic Locations to Choose From

Location	Address	Phone	Hours
Denton Clinic	535 S. Loop 288, Denton, TX 76205	(940) 349-2900	Monday–Friday, 7:30 a.m. to 5 p.m.
Lewisville Clinic	190 N. Valley Parkway, Lewisville, TX 75067	(972) 434-4700	Monday–Friday, 7:30 a.m. to 5 p.m. (closed for lunch, noon–1 p.m.)

Both clinics run the same fee schedule and offer the same core services. Pick whichever is closer to home or work.

Booking Your Appointment, Step by Step

Step 1 — Decide Exactly What You Need

A school vaccine, an adult shot, STI testing, TB services, primary care — name the specific service when you call. It makes the eligibility conversation much faster.

Step 2 — Check Your Insurance Status First

Have your insurance details ready, or know that you don't have any. For kids, check CHIP or Medicaid status. For adults, ask whether Adult Safety Net applies to you.

Step 3 — Track Down Your Records

For vaccines, bring the most complete immunization record you can find. This matters even more for kids who need a multi-dose series.

Step 4 — Call the Right Clinic

Denton: (940) 349-2900. Lewisville: (972) 434-4700. Ask three things — do I qualify, is there a fee, do I need an appointment.

Step 5 — Confirm What to Bring Before You Hang Up

Nail down documents in advance, especially for kids under 18, since a parent or guardian must attend in person.

A Realistic Example

Say a Lewisville mom has a 10-year-old on her employer's insurance. The plan technically covers vaccines, but only up to a fixed dollar cap each year — and by October, they've already hit it. She assumes her son doesn't qualify for DCPH's program since he's "insured" on paper.

In reality, this is exactly the underinsured category TVFC exists for. She calls ahead, explains the cap's been reached, and brings the insurance card to confirm it. Her son gets his remaining shots at the $10 TVFC rate instead of going without them or paying full retail price elsewhere.

Documents to Bring, at a Glance

Photo ID for the adult patient, or the parent/guardian if the patient is a minor
Completed clinic paperwork packet, downloaded in advance when possible
Complete immunization/shot record — not just a school nurse's note
Medicaid or CHIP card, if applicable
Proof of household income and recent tax documents, for financial screening (Primary Care or Women's Health)
Cash, credit, or debit card to cover any applicable fee

📌 Good to Know: Late July and early August are DCPH's busiest weeks, driven by back-to-school immunization deadlines. If your child needs required shots for the coming school year, call well ahead — waiting until the week before class starts usually means a longer wait than you'd expect.

Lost Your Shot Records? ImmTrac Can Help

Misplaced immunization records are more common than you'd think, and schools, employers, and colleges usually won't accept "I'm pretty sure I had that one." ImmTrac is a free, secure immunization registry run by the Texas Department of State Health Services, and DCPH can help you enroll at either clinic.

Once your records are in the system, doctors and schools across Texas can pull up your immunization history, which means fewer repeat shots and one less document to hunt down when you need it most.

Common Mistakes That Cost Time or Money

Mistake	How to Avoid It
Assuming every vaccine is free	Confirm your eligibility category and fee before the appointment, not after
Showing up without a complete shot record	A school nurse's note isn't enough — bring the actual record, or ask about ImmTrac
Waiting until the week before school starts	Back-to-school demand spikes in late July — call weeks ahead if possible
Assuming every DCPH program has the same rules	Vaccines, primary care, screening, and women's health each use separate eligibility criteria
Skipping the TB test reading appointment	Return within 48–72 hours or you'll need to retest from the start

Frequently Asked Questions

Q: Does Denton County give out free vaccines?

Q: Can uninsured adults get vaccines in Denton County?

A: Yes. Uninsured adults 19 and older may qualify for routine immunizations through the Texas Adult Safety Net program at $10 per vaccine. Some Texas Medicaid enrollees qualify for select vaccines as well.

Q: My child has insurance, but it doesn't cover all vaccines. Do we still qualify for TVFC?

A: Likely yes, under the underinsured category. Bring your insurance card to the appointment so staff can confirm exactly which vaccines fall outside your plan's coverage.

Q: Does Denton County Public Health offer primary care for uninsured residents?

A: Yes. The Primary Health Care Program serves uninsured Denton County residents after a financial and medical screening, with co-pays starting at $0 based on income. CHIP and Children's Medicaid patients don't pay a co-pay.

Final Thoughts

Denton County Public Health won't cover everything, and it isn't always free — but for residents without a regular provider, it fills a real gap. A $10 vaccine, a $30 STI screening, or a sliding-scale primary care visit can be the difference between getting care and putting it off indefinitely.

The key is knowing which program applies to your exact situation before you show up. Double-check your eligibility category, gather your paperwork, and call ahead to either the Denton or Lewisville clinic.
