COVID-19 Vaccine Clinic Scheduled for 1,000 Second Doses of Moderna and 1,500 Doses Johnson & Johnson’s Janssen Vaccine

Guadalupe Regional Medical Center, Guadalupe County and the City of Seguin will administer COVID-19 vaccines this Thursday at the Seguin Coliseum at 950 S. Austin, Seguin, TX. On Thursday April 8, 2021 from 9am-5pm 1,500 doses of the Janssen COVID-19 vaccine will be given along with 1,000 COVID-19 Moderna vaccine second doses for those who received their first Moderna vaccine dose on March 11, 2021.

All COVID-19 vaccines are free of charge. Appointments only.

Who is Eligible for Vaccination Now: All individuals ages 18 and older qualify for the Janssen (Johnson & Johnson) and Moderna vaccines. Individuals 16 and older are eligible to receive the Pfizer vaccine.

Appointments for vaccines will be made utilizing the COVID-19 Vaccine Waitlist. You can sign up for the waitlist by visiting the following link: Once you are on the waitlist, you will receive an email from Eventbrite when a vaccine appointment becomes available and you will have 12 hours to respond to the email and set your appointment. After 12 hours of no response, your spot on the waitlist will roll off and you will need to sign up again.

Those without a computer, internet access, or email address can call (830) 386-2219 and leave a message for assistance with signing up for the waitlist.

The vaccine waitlist closes periodically as it becomes full, but re-opens as individuals on the waitlist receive their vaccines. When this occurs, a notification will be posted on the COVID-19 vaccine webpage on the City of Seguin’s website as well as on the City of Seguin Government Facebook page.

Vaccine Brand and Scheduling: The Centers for Disease Control (CDC) states that the Pfizer, Moderna, and Janssen vaccines are not interchangeable with each other. Vaccines will be scheduled in the order of the number assigned to the person on the waiting list based on vaccines availability. As more vaccine becomes available through allocations from the State we will continue to assign appointment times by order of the waitlist without regard to vaccine manufacturer. If you miss an appointment you will have to sign back up on the wait list.

Be Prepared: Persons arriving to the Coliseum for their vaccine will need to bring their State issued photo identification. Participants must wear a face mask, be screened, and practice social distancing. Please bring your immunization card if you are receiving your second dose.
