COVID-19 Vaccine

The Chickasaw Nation joined many groups across the country in receiving the first doses of COVID-19 vaccine. The vaccine is distributed in accordance with Centers for Disease Control and Prevention (CDC) guidance.

With safety being a top priority, Chickasaw Nation health officials state there are many reasons to receive the vaccine as it is the best defense against COVID-19.

Vaccine Distribution

Vaccinations are available to the public at no cost. There are no citizenship, employment, or residency requirements to be eligible.

Vaccines are available by appointment at the Chickasaw Nation Emergency Operations Facility in Ada and at satellite clinics in Ardmore, Tishomingo and Purcell.

Appointments are scheduled online at You will upload a photo of your ID and health insurance card (optional) when scheduling. Health insurance is not required to receive the vaccine, but can be submitted for billing purposes. There is no cost to you.

Individuals who have received their first vaccine dose with another health care organization are strongly encouraged to complete their second dose with the same organization.

Vaccine recipients must be at least 12-years-old to receive the Pfizer-BioNTech vaccine.

Those who have recently had COVID-19 are encouraged to get the vaccine as soon as they recover – there is no wait period unless the patient received treatment for COVID-19 with monoclonal antibodies or convalescent plasma.

Those diagnosed with COVID-19 must be out of quarantine or isolation before scheduling an appointment.

The Chickasaw Nation COVID-19 Vaccine Call Center is available at (580) 272-1312.

In Case of Severe Weather

To keep our patients and employees safe, the Chickasaw Nation COVID-19 vaccination and testing drive-thru operations will be suspended in case of severe weather. During severe weather threats, monitor conditions, closings and delays on, KCNP radio and tribal social media pages. Patients with vaccine appointments scheduled during severe weather operation suspensions will be contacted to reschedule as needed.

General Information about COVID-19 Vaccinations

Much like other common vaccines, such as flu immunizations, chickenpox, hepatitis, HPV and more, the COVID-19 vaccine helps your body develop immunity to the virus. Vaccines work with your immune system so it will be ready to fight the virus if you are exposed. Unlike some vaccines, the COVID-19 does not contain a live virus. Instead, the vaccine helps (or aids) by building antibodies, to protect you if you are exposed.

The U.S. Food and Drug Administration (FDA) has robust scientific and regulatory processes in place to facilitate development and ensure the safety, effectiveness and quality of COVID-19 vaccines. According to the Centers for Disease Control and Prevention (CDC), the U.S. has a longstanding safety system to ensure all vaccines are as safe as possible.

The FDA issued full approval of the Pfizer BioNTech COVID-19 vaccine, which is marketed under the brand name “Comirnaty.” The approval covers prevention of COVID-19 in individuals 16 years of age and older. The vaccine is still approved under the emergency use authorization (EUA) for adolescents 12-15 years of age, and for the additional booster dose in immunocompromised individuals.

Pfizer’s Comirnaty is the only vaccine offered by Chickasaw Nation.

What to Expect When Receiving the First Vaccine:

  • Arrive at your scheduled appointment time and location. For the drive-thru location in Ada, expect to remain in your vehicle at all times. All other locations provide vaccinations inside the clinic.
  • Pets are not allowed in the vehicle (no exceptions). For the safety of patients and staff, traffic will move slowly at the drive-thru location.
  • For the safety of patients and staff, traffic will move slowly at all Chickasaw Nation vaccine drive-thru locations.
  • Following the vaccination, there is a required 15-minute observation time.
  • Recipients will receive a vaccine record card that will be required for the second dose.
  • Vaccine recipients should consult with a primary care provider if there are questions or concerns regarding side effects after either dose.

What to Expect When Receiving the Second Dose Vaccine:

  • You must receive a first dose through the Chickasaw Nation, in order to be eligible for a second dose through the Chickasaw Nation. If an individual has received a first dose through any agency or entity outside of the Chickasaw Nation, the second dose should also be scheduled through the same agency.
  • Second dose timeline: The Pfizer vaccination is given 21 days after the first dose. The Pfizer vaccine is the only vaccine offered at all locations.
  • Patients will be sent an email reminder 15 days after receiving the first dose of the vaccine. The email reminder will include a link to schedule a second dose vaccination appointment.
  • Please have your vaccination verification card and a photo ID ready.

Additional Booster Dose

The FDA and the Centers for Disease Control and Prevention (CDC) recommend an additional booster dose for people who are moderately to severely immunocompromised and received the first and second doses of the Pfizer or Moderna vaccine.

Examples of these conditions are listed below:

  • Receiving active cancer treatment for tumors or cancers of the blood
  • Received an organ transplant and taking medicine to suppress the immune system
  • Received a stem cell transplant within the last two years or are taking medicine to suppress the immune system
  • Moderate or severe primary immunodeficiency such as DiGeorge syndrome, Wiskott-Aldrich syndrome
  • Advanced or untreated HIV infection
  • Active treatment with high-dose corticosteroids or other drugs that may suppress immune response

The CDC confirms that the Pfizer vaccine can be used as an additional booster dose in those who received the first and second doses of the Moderna vaccine. At this time, the CDC does not recommend an additional booster dose for those who previously received the Johnson & Johnson vaccine.

Additional booster dose vaccinations are anticipated to be available to the general population, 18 and above, as early as the end of September and are recommended eight months from the time an individual received their second vaccine.

Frequently Asked Questions

  1. What are the benefits of COVID-19 vaccination?
    Widespread vaccination is the single most effective way to control the COVID-19 virus. It will help reduce critical illness rates and clinic, emergency department and hospital visits. It will also decrease the need for testing, treatment and more importantly, reduce deaths.
  2. What is the vaccine effectiveness?
    The Pfizer COVID-19 vaccine has reported efficacy of between 90-95%. 
  3. How is the Pfizer COVID-19 vaccine given?

    Pfizer COVID-19 vaccine: Administered in two doses in the shoulder muscle (deltoid), intramuscularly (IM) (like a flu or tetanus shot). The second dose is administered 21 days after the first dose.

  4. Can I get a COVID-19 infection from the vaccine?
    No, this is not possible. The vaccine contains no virus or virus particles. The Pfizer COVID-19 vaccine allows your body to develop immunity. The antigen (what your body’s immune system reacts to which helps you develop immunity to the real COVID-19 virus should you get infected) is a piece of genetic code, which instructs your cells to make “spike” protein that looks like the protein on the virus. This bioengineered genetic code snippet is contained in a small fat molecule. The fat particle is taken by your cells shortly after immunization. Your cell makes spike proteins after reading the code and then sends these proteins into the bloodstream. Your body’s T cells and B cells react to the protein and attack it, causing an immune response. People who experience symptoms after being vaccinated are developing immunity. The cells also create memory to attack the virus if you are infected at a later date with COVID-19. This will keep the virus from doing significant damage to your body.
  5. What are the side effects of the COVID-19 vaccines?

    It is important to remember that a vaccine is designed to create an immune response. Vaccine reactions, such as arm soreness, low-grade fever, muscle aches and pain, mild cough and headache, are common and a sign that your body may be appropriately responding to the vaccine. Most people do not report any significant symptoms. For those who do, most report them for about 24 hours and a few up to 48 hours. As mentioned above, the vaccines are administered as a two-part series. Some people have reported more significant symptoms after the second injection.

    Long-term safety (over six months) by definition has not been established as not enough time has elapsed since the studies were conducted.

  6. How long is the protection from a COVID-19 vaccine expected to last?
    At this time, we do not have enough data collected to determine how long the vaccine is effective. However, early vaccine trial recipients have continued to see vaccine efficacy in protecting them from infection lasting up to four months. It is believed that protection will last significantly longer than this. This information will be updated as more data is collected.
  7. If I take the COVID-19 vaccine, may I stop wearing a mask?
    COVID-19 precautions, such as wearing masks and responsible distancing, will continue to be recommended as a safeguard against COVID-19 until widespread vaccination is achieved and shown to be effective.
  8. If I had my first COVID-19 vaccine through a different provider, such as my local health department, may I get the second dose, through the Chickasaw Nation?
    Please plan to receive your second dose from the same provider. This is important for several reasons. Departments, including the Chickasaw Nation, must plan to have enough vaccine on hand to ensure those vaccinated at their sites also have access to a second dose.
