Register for COVID-19 Vaccine

Due to the FDA's decision to pause the use of the Johnson & Johnson COVID-19 vaccine, NRG Park will only administer the Pfizer vaccine until further notice. Other HCPH vaccination sites will operate as scheduled, administering the Moderna vaccine.

HCPH will continue to provide information and updates as they become available.

How do I register without access to Internet or a computer?

If you or a loved one do not have access to Internet or a computer, please use the phone number listed above to schedule your appointment.

Can you walk me through the registration process?

To learn more about the VacsTrac system - Harris County Public Health's (HCPH) COVID-19 vaccine registration application - view the How Do I Register? steps outlined here.

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

Because COVID-19 vaccine sites are often drive-thru, it is encouraged that those who have registered for an appointment have access to a personal vehicle. If you do not have access to a vehicle, please contact 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.

Registration Guidelines and Eligibility

New appointments will open up with each vaccine shipment received by Harris County Public Health (HCPH). Individuals will be randomly selected and notified via email. You will have 48 hours to schedule your appointment before being being put back in rotation for an appointment.

Beginning March 29, 2021, all adults will be eligible to receive a COVID-19 vaccine in Texas. Learn more here.

Everyone who registers will be prioritized equally. They will also be selected at random (rather than on a first come, first serve basis) from the following age cohorts prioritized first: 75+, 65 - 74, 55 - 64, 45 - 54, 35 - 44, 25 - 34, 25 - 34, and 18 - 24. Those under the age of 18 are not eligible to receive the Moderna vaccine.

Individuals are selected from the HCPH registrations at random and will be notified by email, text message, and/or phone that an appointment is available.

Those who registered online will be provided with a personal link to make an appointment.
Those who registered by phone (832-927-8787) will either be provided with a personal link to make an appointment or HCPH will provide them with an appointment date and time - depending on whether they have Internet access and an email address.

Once notified, you will be given a specified amount of time to make an appointment before the slot is offered to someone else. Those individuals who do not make an appointment within the specified timeframe will simply go back into the registration pool for a future appointment. Those who have been able to get the vaccine elsewhere will be able to let HCPH know that they no longer need an appointment so can be removed from the registration.

Do I Qualify?

Eligibility to receive the COVID-19 vaccine in the State of Texas has been expanded to include all adults. Please note that eligibility for younger adults may depend on the vaccine as Pfizer can be administered to those 16 years and older while both Moderna and Johnson & Johnson can be administered to those 18 years and older.

How Do I Register?

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

Step 1. What You Need to Know

HCPH is administering the Moderna vaccine, which requires two doses. This vaccine can be provided to individuals 18+ years of age. (Note that individuals vaccinated at the NRG Park site will receive the Pfizer vaccine. Learn more here.)
To assist with social distancing, vaccines will only be provided at "drive-through" locations.
Keep in mind that only certain dates will be available and that the current supply of vaccines may be limited.
- There are a limited number of vaccine doses available.
- Due to limited supply, it may take weeks to be randomly selected to schedule an appointment.
There is no charge for the vaccine or administration.

Step 2. Making An Appointment

Click on the Register Now link to go to HCPH's COVID-19 vaccine app.
Follow the instructions on the app to register for the vaccine. You will be asked a series of questions to determine if you qualify for the current distribution group.
If you qualify, you will be invited later to schedule your appointment. The way in which groups will be prioritized can be found here.
1. When you have registered for a vaccine through HCPH, please allow 15 - 30 minutes for the confirmation email and text message to arrive.
Once you have been randomly selected, you will be notified via email, text message, and/or phone with a link to schedule your appointment. If you registered by phone and do not have access to Internet, you will be provided a date and time for appointment.
Once the 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.

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 drive-through clinic.
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 Moderna vaccine. Individuals who received the Pfizer vaccine at the NRG Park site should expect a text/email message to schedule their 2nd dose appointment. 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.

Mass Vaccination Site at NRG Park

Beginning the week of February 22, 2021, Harris County Public Health (HCPH) and Houston Health Department (HHD) will collaborate with FEMA on a new COVID-19 mass vaccination site located at NRG Park. This site is intended to prioritize the area's most vulnerable populations and underserved communities.

The COVID-19 mass vaccination site will fully-vaccinate approximately 126,000 people by serving 6,000 per day seven days per week for three weeks. After that, they will transition to administering second doses for the following three weeks.

This site will provide the Pfizer vaccine. Learn more about this vaccine here.

The NRG Park site is appointment only and people with appointments should arrive no sooner than 30-minutes before their schedule slot. People without appointments will be turned away.

How Can I Register for NRG Park?

Both HCPH and HHD will use their registration pools to schedule appointments for the drive-thru site. Individuals will be scheduled for this location if they meet the qualifications outlined by the department for both vaccination and risk.

Those who qualify may call the department’s Area Agency on Aging at 832-393-4301 to leave a voicemail with their name and phone number. Calls will be returned for screening and scheduling. An online registration portal for those who meet the criteria is available at HoustonEmergency.org/covid19.
