Step 1. What You Need to Know

    • 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

Individuals can sign up and schedule instantly. Residents are encouraged to plan for their 2nd dose 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. 

Step 5. Scheduling Your Booster Dose

Beginning October 27th, HCPH is providing Pfizer, Moderna and Johnson & Johnson Booster doses across our vaccination sites. A booster dose is given when the immune response to an initial vaccine series (1st & 2nd doses) is likely to have decreased over time.

- Age 18+ who have underlying medical conditions
- Age 18+ who work or live in high-risk settings
