On this page are frequently asked questions (FAQs) about COVID-19 vaccines in development and their distribution across Texas.

On this page:


Basics

How are the COVID-19 vaccines different from other vaccines?

Different types of vaccines work in different ways to offer protection. But every type of vaccine works by teaching our bodies how to make cells that trigger an immune response. That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies.

Currently, there are three main types of COVID-19 vaccines that are or soon will be undergoing large-scale (Phase 3) clinical trials in the United States:

  • mRNA vaccines
  • Protein subunit vaccines
  • Vector vaccines

COVID-19 vaccines do not use the live virus and cannot give you COVID-19. The vaccine does not alter your DNA. COVID-19 vaccination will help protect you by creating an immune response without having to experience sickness.

Learn more about how COVID-19 vaccines work on the Understanding How COVID-19 Vaccines Work section of the Centers for Disease Control and Prevention (CDC) website.

Why should I take the COVID-19 vaccine?

Getting this vaccine once it is available to you represents one step that you can take to get the Texas economy, and our day-to-day lives, back to normal.

How do I know whether the COVID-19 vaccine is safe?

Safety is a top priority while federal partners work to make COVID-19 vaccines available. The new COVID-19 vaccines have been evaluated in tens of thousands of volunteers during clinical trials. The vaccines are only authorized for use if they are found to be safe.

Even though they found no safety issues during the clinical trials, CDC and other federal partners will continue to monitor the new vaccines. They watch out for serious side effects (or “adverse events”) using vaccine safety monitoring systems, like the new V-safe After Vaccination Health Checker app.

For the most up-to-date information, see the Vaccine Safety section of the CDC website.

To learn about CDC’s new vaccine safety monitoring system, see the V-safe After Vaccination Health Checker section of the CDC website.

Vaccine Availability in Texas

Is Texas following CDC’s recommendations for vaccine priorities? If not, why not?

While Texas does consider all CDC recommendations, it’s ultimately up to our state’s medical experts to decide vaccine priorities for Texas. DSHS’s Expert Vaccine Allocation Panel (EVAP) provides additional recommendations to the Health Commissioner. The EVAP is taking a medical risk-based approach to identify who is at the highest risk of contracting COVID-19 or at increased risk for severe illness from COVID-19.

Who decides how many vaccines Texas gets?

CDC determines how many doses of vaccine Texas will receive each week, based on population. Once the Texas Department of State Health Services (DSHS) is notified of the number of doses expected the following week, DSHS staff presents possibilities for vaccine distribution to the Expert Vaccine Allocation Panel (EVAP). The panel makes modifications and recommendations to the Commissioner of Health, who makes the final decision on that week’s distribution.

Who decides how to distribute the vaccine in Texas?

In Texas, DSHS distributes the vaccine with the guidance of the EVAP, appointed by the Health Commissioner, Dr. John Hellerstedt.

How did DSHS decide who to immunize first?

The Commissioner of Health appointed an EVAP to make recommendations on vaccine allocation decisions. This includes identifying groups that should be vaccinated first. The goal is to provide the most protection to vulnerable populations and critical state resources. EVAP developed Vaccine Allocation Guiding Principles (PDF) that provide the foundation for the Texas vaccine allocation process.

Who can get the vaccine now?

As of Monday, March 29, 2021, everyone age 16 and older is now eligible to receive a COVID-19 vaccine in Texas.

The state’s Expert Vaccine Allocation Panel recommended opening vaccination to everyone who falls under the current Food and Drug Administration emergency use authorizations. All vaccines are authorized for people age 18 and older. The Pfizer vaccine is authorized for people 16 and older.

If I’m eligible for vaccine now, how do I get one?

There are multiple tools to help you find vaccine in Texas. Check these tools frequently, as more providers and pharmacies will be added to each over the coming weeks.

Large Vaccination Hub List

Beginning in January, Texas established large vaccination sites or hubs around the state. Check the COVID‑19 Vaccination Hub Providers page to find a hub near you and learn how to register.

Retail Pharmacies List

Check your local pharmacy’s website to see if vaccine appointments are available. On March 29, the White House announced that the Federal Retail Pharmacy Program is doubling the number of pharmacies receiving the vaccine by April 19. To find out which pharmacies are participating in the program, visit CDC’s Federal Retail Pharmacy Program website.

Texas Public Health Vaccine Scheduler

The new Texas Vaccine Scheduler helps Texans get scheduled for a COVID-19 vaccine at clinics hosted by participating Texas public health entities.

Register online at GetTheVaccine.dshs.texas.gov. You will be notified by email or text when and where to get the vaccine. If there’s not an available clinic near you, you will be directed to other places to get your vaccine.

Call (833) 832-7067 if you don’t have internet or need help signing up. Call center support is available 7am-7pm, 7 days a week.

Spanish language and other translators are available to help callers.

Tips for Your Vaccine Search

When searching for a vaccination site, remember:

  • While vaccine supply and distribution are expanding, not all local providers have vaccine each week and hubs may have waiting lists.
  • Do not show up at a hub or provider looking for a vaccine.
  • Instead, check the provider’s website. Call only if the website doesn’t answer your questions.

Do you know someone who is eligible for a vaccine but doesn’t have internet access? Please let them know they can call (833) 832-7067 for referral to a local vaccine provider.

I am at least 75 years old and can’t leave my house. How can I get a COVID-19 vaccine?

Texas launched the COVID-19 “Save Our Seniors Initiative” to identify and vaccinate Texans who are 75+ or are homebound.

To register, contact your Local County Judge or Local Office for Emergency Management to let them know you want to sign up.

The list of counties changes weekly. Counties currently participating include Aransas, Bowie, Brooks, Calhoun, Cameron, Cass, Coke, Dallas, DeWitt, Duval, Henderson, Hidalgo, Hockley, Hopkins, Karnes, Kinney, Leon, Liberty, Lubbock, Madison, Marion, Matagorda, Mason, Maverick, Orange, Palo Pinto, Rains, Robertson, Sabine, San Augustine, San Jacinto, San Patricio, Shelby, Sherman, Sutton, Terry, Titus, Trinity, Upshur, Val Verde, Van Zandt, Waller, Webb, Willacy, Williamson, and Wood.

Who can provide vaccines, and how does that happen?

Any facility, organization or healthcare provider licensed to possess or administer vaccine or provide vaccination services is eligible to enroll as a COVID-19 vaccine provider. Each facility or location, including those that are part of a hospital system or clinic network, must register at EnrollTexasIZ.dshs.texas.gov/emrlogin.asp and complete the CDC COVID-19 Vaccination Program Provider Agreement.

How can a long-term care facility get residents, staff and providers vaccinated now that the federal partnership sign-up has closed?

A long-term care facility that has not already signed up for the federal partnership program has other options to get their residents, staff and providers vaccinated. See Long-Term Care Options for COVID-19 Vaccination (PDF) for additional information.

I am hearing that the DSHS Pharmacy Branch has vaccines available. Can I get my vaccine there?

No. The DSHS Pharmacy Branch is not a public pharmacy and does not vaccinate people. It receives and distributes medications to providers across the state. Please do not call or visit the DSHS Pharmacy Branch, as they do not vaccinate anyone at this location.

What should I do to protect myself and others before I'm fully vaccinated?

Practice the same safety habits you’ve been doing to prevent the spread of COVID-19. Take the following precautions to limit exposure for yourself and others:

  • Wear a mask or cloth face covering in public and when around people who don’t live in your household, especially when social distancing is not possible.
  • Practice social distancing and avoid close contact with others:
    • Outside your home: Stay at least 6 feet away from others and avoid crowded places.
    • Inside your home: Avoid close contact with household members who are sick. Avoid sharing personal items and use a separate room and bathroom for sick household members, if possible.
  • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing. If soap and water are not readily available, you can use an alcohol-based hand sanitizer that contains at least 60% alcohol.
  • Clean and disinfect frequently-touched objects and surfaces using a household disinfectant on List N: Disinfectants for COVID-19.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash and wash your hands.
  • Stay home when you are sick.

Effectiveness

Will vaccines prevent people from getting and spreading COVID-19?

COVID-19 vaccines are new and are still being evaluated. Some COVID-19 vaccines may prevent severe illness, while others may prevent people from getting COVID-19 altogether. Others may be effective to prevent spreading COVID-19. CDC and DSHS will keep the public informed as they learn more.

How effective will the vaccine be against COVID-19, and for how long?

Different vaccines are proving to have different efficacy rates. Some manufacturers are reporting 90% to 95% protection at 1–2 weeks after receiving the final dose. At this time, experts do not know how long protection will last or whether a booster shot will be necessary later, after the initial recommended vaccine dose(s). CDC and DSHS will keep the public informed as they learn more.

After we get vaccinated, will we still need to wear a mask or cloth face covering and socially distance?

Yes. Experts are still learning about the protection that COVID-19 vaccines provide under real-life conditions. The vaccine is not expected to be 100% effective. At this time, CDC recommends that everyone continue to use all the tools to protect ourselves and others from getting and spreading the virus. Wear a mask or cloth face covering whenever you are out in public or when around people who don’t live in your household. These masks or face coverings help when you can’t avoid being in the same space as others.

Wearing a mask or cloth face covering does not mean you don’t need to stay a safe distance from others. Social distancing, or staying at least 6 feet apart from others, is still necessary to keep you and others safe.

How long will I have to wear a mask, stay six feet from others and wash my hands?

Experts at CDC are learning about the protection that COVID-19 vaccines provide under real-life conditions. So, once you get vaccinated, keep wearing your mask, washing your hands and staying six feet from others until you hear differently from CDC and DSHS.

Immunity

Will the immunity after getting COVID-19 last longer than the protection provided by the vaccine?

We are still learning about how long a recovered person is protected by “natural immunity.” Early evidence suggests that immunity after having COVID-19 may not last very long.

We also don’t know yet how long the vaccines’ protection lasts, called “vaccine-induced immunity.” CDC and DSHS will keep the public informed as more information becomes available.

Will we ever achieve “herd immunity” in Texas?

Experts are still learning about what percentage of Texans would need to be vaccinated to achieve herd immunity. This term describes when enough people have protection, either from a previous infection or from vaccination, that it is unlikely a virus or bacteria can spread between people in a community and cause disease. The percentage needed to reach herd immunity varies by disease. CDC and DSHS will keep the public informed as more information becomes available.

Getting Vaccinated

Do I need to get vaccinated if I’ve already recovered from COVID-19?

Yes. Immunity from the COVID-19 vaccine may last longer than the natural immunity you get if you’ve already had COVID-19.

People who currently have COVID-19 should not be vaccinated while being sick.

Will the COVID-19 vaccine be one or two shots? How long after the first dose do I take the second one?

All but one of the COVID-19 vaccines currently in development need two shots to be effective. You need two doses from the same manufacturer, spaced 21 or 28 days apart. You will get full protection from the vaccine usually 1–2 weeks after getting your second dose.

At this time, experts do not know how long protection will last or whether a booster shot will be necessary later, after the initial recommended vaccine dose(s). CDC and DSHS will keep the public informed as they learn more.

Can I just take one of the two doses?

For all but one of the COVID-19 vaccines currently in development, you will need two shots for full protection. You will need two doses from the same manufacturer, spaced 21 or 28 days apart, depending on the vaccine manufacturer. You will get full protection from the vaccine usually 1–2 weeks after getting your second dose. Get the second shot even if you have side effects from the first shot, unless the vaccination provider or your healthcare provider tells you not to get the shot.

When you get the vaccine, you will receive information about what kind of vaccine you got and when you need to come back for your second dose. You can register and use the new V-safe After Vaccination Health Checker to receive health check-ins after you receive a COVID-19 vaccination, as well as reminders to get your second dose if you need one.

If you choose to get only one dose, the amount of protection you may have is not known.

Do I have to get the second dose from the same location I got the first dose? My provider doesn't know when they'll get another vaccine shipment.

No, you do not have to get your second dose from the same location as you got the first dose. Providers should receive second doses for those who received their first dose. However, if you need to locate a second dose, be sure it’s from the same manufacturer and after the recommended dose interval. For more information, refer to the vaccination materials you received from your provider when you received your first dose. Those may include a vaccination fact sheet and/or record card.

If I'm unable to get the second dose within the recommended timeframe, do I have to start all over?

No, you do not have to start all over. Missing the suggested interval delays full protection. But you can still get the second dose later if you have difficulty getting it within the recommended time. Just don’t get it earlier than recommended.

According to CDC, if you need help scheduling your vaccine appointment for your second shot, contact the location that set up your appointment for assistance. Both COVID-19 mRNA vaccines will need two shots to get the most protection.

The timing between your first and second shot depends on which vaccine you received. You should get your second shot:

  • for the Pfizer-BioNTech vaccine: 3 weeks (or 21 days) after your first shot;
  • for the Moderna vaccine: 1 month (or 28 days) after your first shot.

You should get your second shot as close to the recommended 3-week or 1-month interval as possible. However, there is no maximum interval between the first and second doses for either vaccine. You should not get the second dose earlier than the recommended interval.

For more information, visit the What to Expect after Getting a COVID‑19 Vaccine section of the CDC website.

For information about the Pfizer vaccine, visit the Information about the Pfizer-BioNtech COVID-19 Vaccine section of the CDC website.

For information about the Moderna vaccine, visit the Information about the Moderna COVID-19 Vaccine section of the CDC website.

Which vaccine should I get for COVID-19? Do I have a choice?

You always have a choice about your health care. Talk to a healthcare provider to get information specific to your situation.

Does the vaccine I choose depend on my age or underlying conditions?

Different COVID-19 vaccines may be more suitable for certain people. Your age and/or underlying conditions may also affect when you are eligible to get the vaccine. Talk to a healthcare provider to get information specific to you and the COVID-19 vaccine.

How long after I get the COVID-19 vaccine before I am protected?

For the two-dose vaccines, the process of getting fully vaccinated takes over a month in total. You will get full protection from the vaccine usually 1–2 weeks after getting your second dose.

Talk to a healthcare provider to get information specific to your COVID-19 vaccine.

Can I get the COVID-19 vaccine if I have COVID-19?

Talk to your healthcare provider about the timing of your vaccination(s) if you have been sick with COVID-19.

What are some side effects from the vaccines for COVID-19?

COVID-19 vaccines are associated with a number of side effects, but almost all of them are mild. They include pain and redness at the injection site, fatigue, headache, body aches and even fever.

Having symptoms like fever after you get a vaccine is normal and a sign your immune system is building protection against the virus. The side effects from COVID-19 vaccination may feel like flu, but they should go away in a few days.

If you get the vaccine and experience severe side effects or ones that do not go away in a couple of days, contact your healthcare provider for further instructions on how to take care of yourself.

You can register and use the new V-safe After Vaccination Health Checker to receive health check-ins after you receive a COVID-19 vaccination, as well as reminders to get your second dose if you need one.

To learn what side effects to expect and get helpful tips on how to reduce pain and discomfort after your vaccination, visit the What to Expect after Getting a COVID-19 Vaccine section of the CDC website.

Does the vaccine react poorly with any medications, or do the prescriptions I'm taking preclude me from being able to get a vaccine?

You will need to check with your healthcare provider about whether your medication will interfere with being vaccinated.

Safety

How do I report it if I have a bad reaction to a vaccine?

CDC has a new smartphone-based tool for this effort called v-safe. This tool helps CDC check in on people’s health after they receive a COVID-19 vaccine. When you get your vaccine, you should also receive a v-safe information sheet telling you how to enroll in v-safe. If you enroll, you will get regular text messages directing you to surveys. Use these surveys to report any problems or adverse reactions you have after receiving a COVID-19 vaccine.

Read about v-safe with the V-safe Information Sheet (PDF).

According to CDC’s website, CDC and FDA encourage the public to report possible side effects (called adverse events) to the Vaccine Adverse Event Reporting System (VAERS). This national system collects these data to look for adverse events. Those may include ones that are unexpected, ones that appear to happen more often than expected or ones that have unusual patterns of occurrence. Reports to VAERS help CDC monitor the safety of vaccines. Safety is a top priority.

For more information about the difference between a vaccine side effect and an adverse event, visit the Understanding Side Effects and Adverse Events section of the CDC website.

For more information about the reporting system, visit the VAERS website or call 800-822-7967.

You should also let your doctor know about your reaction. According to CDC, healthcare providers will need to report some vaccine side effects to VAERS.

Can the COVID-19 vaccine make me sick or give me COVID-19?

No. COVID-19 vaccines do not use the live virus and cannot give you COVID-19. The vaccine does not alter your DNA. COVID-19 vaccination will help protect you by creating an immune response without having to experience sickness.

To learn about COVID-19 vaccines, visit the Different COVID-19 Vaccines section of the CDC website.

Can children get the vaccine, or will they rely on their natural immune system to protect them?

At this time, experts do not know how safe the COVID-19 vaccine is for children. People 16 years old and older are currently eligible to get the vaccine if they are in a priority population.

Can pregnant women get the vaccine?

At this time, experts do not know how safe the COVID-19 vaccine is for people who are pregnant. Data from studies are limited. But experts believe COVID-19 vaccines are unlikely to pose a risk to people who are pregnant. If you are pregnant and are eligible to get the vaccine, you may choose to get vaccinated. Discuss your options and any concerns with your healthcare provider.

For more information about COVID-19 vaccines and pregnancy, visit the Vaccination Considerations for People who are Pregnant or Breastfeeding section of the CDC website.
