What do I do about my appointment if I do not have access to a personal vehicle?

Residents who do not have access to a personal vehicle may still receive vaccines at HCPH vaccination sites. Please call the health department (i.e., Harris County Public Health, Houston Health Department) you registered with for alternative arrangements. For appointments with Harris County Public Health, call the HCPH Vaccine Hotline at 832-927-8787.

I am not currently eligible for the vaccine. What can I do?

Both Harris County Public Health (HCPH) and Houston Health Department (HHD) use a registration system to help manage those individuals who are interested in being vaccinated against COVID-19. Only those who qualify for the current distribution phases will have an appointment scheduled when available. However, residents can still sign up to be contacted when the distribution phase with which you are eligible opens. Learn more here.

What COVID-19 vaccine should I get - Moderna, Pfizer, or Johnson & Johnson?

You should receive the first vaccine you are eligible and able to receive. All of the vaccines being offered by Harris County are safe and effective and are virtually 100% effective at preventing hospitalizations and deaths. The primary difference is that Pfizer and Moderna vaccines both require two shots whereas the Johnson & Johnson vaccine can be administered in only one shot.

Learn more about each vaccine below.

Eligibility to receive the COVID-19 vaccine in the State of Texas has been expanded to include all adults.

How Do I Register?

Please note the steps outlined below are for Harris County Public Health (HCPH) only. Steps for other providers may differ.

Beginning April 21, 2021, NRG Park will accept walk-ups in addition to those residents who have registered for an appointment. Registration will not be required but is highly encouraged.

Step 1. What You Need to Know

  • Both the Pfizer and Moderna vaccines require two doses. Moderna can be provided to individuals 18+ years of age. (Note that individuals vaccinated at the NRG Park site will receive the Pfizer vaccine, which can be provided to individuals 16+ years of age. Learn more here.)
    • Keep in mind that only certain dates will be available and that the current supply of vaccines may be limited.
  • There is no charge for the vaccine or administration.
  • The vaccine is free of charge


Step 2. Making An Appointment

  1. Click on the Register Now link to go to HCPH's COVID-19 vaccine app. 
  2. Follow the instructions on the app to register for the vaccine. 
  3. Once your appointment is scheduled, you will receive a confirmation including QR code. You must bring your QR code with you to the scheduled appointment.


Step 3. Receiving Your Vaccine

If you do not have transportation for your vaccination appointment, please contact the HCPH Vaccine Hotline at 832-927-8787.

  1. When arriving to your scheduled appointment...
    • Ensure you have your QR code for staff to scan. This can be printed out or a screenshot from your confirmation email.
    • Follow signs and directions posted to navigate the vaccination site.
  2. If, for whatever reason, you are unable to make your appointment and must cancel, you will need to complete the registration process again. Canceled appointments will not be rescheduled. 

Step 4. Scheduling Your Second Dose

Currently, HCPH sites administer the Johnson & Johnson, Moderna and Pfizer vaccines. Individuals can sign up and schedule instantly. Residents are encouraged to plan for their 2nd doses 3 weeks after their 1st dose. Learn more here.

Please remember, if you received the Moderna or Pfizer vaccine you will need two doses. Upon completion of your scheduled first dose, you will receive a notification through text and/or email to schedule your 2nd dose closer to the date of your 2nd appointment. (Roughly 3 weeks) If there is no appointment availability, you will continue to receive notifications daily until you can sign up.
