COVID-19 Vaccine Guidance

As hospitals and doctor’s offices work diligently to vaccinate our community as quickly as possible, we encourage everyone to:

  • Check the website. Memorial Hermann's website is the best source of accurate, up-to-date information related to our COVID-19 vaccine distribution process. By limiting calls and unscheduled visits to our hospitals and doctor’s offices that are related to vaccine inquiries, we can more effectively assist and provide care for our patients and their loved ones.
  • Register for Vaccination. As a state-designated COVID-19 vaccine distribution hub, Memorial Hermann invites all members of the community 16 years of age and older to register for the opportunity to receive the COVID-19 vaccine at a Memorial Hermann vaccination clinic.

    Registered individuals will be notified when appointments are available. Memorial Hermann will make appointments available based on vaccine supply and will prioritize vaccine distribution in accordance with guidance from the Texas Department of State Health Services. Register Now »

About Vaccines

Vaccines train the body’s immune system to recognize and fight viruses and bacteria. When the body is exposed again to a virus after being vaccinated against it, the body is immediately ready to fight the illness. Vaccines currently save millions of lives every year by preventing diseases like diphtheria, tetanus, pertussis, measles and influenza.

Getting a vaccine approved by the Food and Drug Administration (FDA) is a rigorous one, to ensure both safety and efficacy. Read more about the FDA’s approval process.

During a public health emergency, the FDA can issue an EUA to allow the use of unapproved medical products (or unapproved uses of approved medical products) to diagnose, treat or prevent serious or life-threatening diseases. Certain safety, efficacy and other criteria must be met.

A virus can spread very quickly throughout a community infecting many people. However, if enough people get vaccinated, germs cannot spread from person to person as quickly and the vast majority of people will not get sick. This is what is known as herd immunity. Herd immunity protects everyone, especially those people who cannot receive a vaccine for one reason or another, those who do not have a strong immune response to vaccines, and those with serious allergies or weakened immune systems.

About COVID-19 Vaccines

Vaccines developed by Pfizer, Moderna and Johnson & Johnson have been granted Emergency Use Authorization (EUA) by the FDA and are being distributed across the United States.

Although three vaccines are available in the United States at this time, more are in development. To learn about ongoing trials and new developments, visit the Coronavirus Prevention Network website. The network was formed by the National Institute of Allergy and Infectious Diseases (NIAID) at the U.S. National Institutes of Health.

Each vaccine will undergo the same stringent FDA review process before it receives approval or EUA, which means the FDA has determined there is substantial evidence that the vaccine is safe and effective in preventing a COVID-19 infection.

While the three COVID-19 vaccines currently available to us are approved under an Emergency Use Authorization (EUA) by FDA, that does not mean they were improperly studied or vetted. The FDA is globally respected for its scientific standards of vaccine safety, effectiveness and quality. The organization has made it abundantly clear that they evaluated data from tens of thousands of study participants to fully ensure that each vaccine candidate was safe for the general public (those age 16 and older for the Pfizer vaccine, and those age 18 and older for the Moderna and Johnson & Johnson vaccines). In addition to these clinical trials, we now have observations following the administration of hundreds of millions of doses to date in the U.S.

It is a common misconception that vaccines prevent someone from contracting the virus. Vaccines train the body’s immune system to recognize and fight viruses and bacteria. When the body is exposed to a virus after being vaccinated against it, the body is immediately ready to fight the illness. Because the body is able to respond more quickly, you are less likely to experience symptoms of the illness, especially severe and life-threatening ones. Based on clinical trials and observations following the administration of more than hundreds of millions of doses, we know the COVID-19 vaccines are extremely effective in preventing severe illness and death from the virus.

At this time, there is not enough data about the vaccines to know how long they will provide protection from COVID-19. However, research has shown that the Pfizer and Moderna COVID-19 vaccines are still highly effective six months after being fully vaccinated.

Yes. While doctors do not yet know how long you will be protected after having COVID-19, they do know it is possible to contract the virus again. Getting vaccinated protects you from suffering severe illness, hospitalization and death from COVID-19.

Yes. We all need to continue the 3 W’s – wearing a mask, watching your distance and washing your hands regularly – until we know how long the vaccine protects against the virus and we gain community control of COVID-19.

No. None of the vaccines currently available use a live version of the virus, so a person who receives any of these vaccines cannot contract COVID-19 from the vaccination.

Side effects may vary depending on which vaccine you receive, but common side effects include fatigue, headache, muscle and joint pain, swollen lymph nodes and pain at the injection site, which is generally the upper arm. Before you receive your vaccine, specific information about your vaccine’s anticipated side effects will be provided to you.

The COVID-19 vaccine is currently available to individuals 16 years of age and older. Individuals must be 16 years of age or older to receive the Pfizer vaccine and 18 years of age or older to receive the Moderna or Johnson & Johnson vaccine.

Additional information about the vaccines can be found in the FDA's fact sheets for the Pfizer vaccine, Moderna vaccine and Johnson & Johnson vaccine. You may find general information about the COVID-19 vaccine on the FDA’s website.

Memorial Hermann believes – based on scientific evidence – that the benefits of receiving the Johnson & Johnson COVID-19 vaccine still far outweigh the exceptionally uncommon risks.

We also believe, based on the latest research/scientific evidence, the Johnson & Johnson vaccine is safe, effective and poses little danger when individuals are aware of the risks. Furthermore, the Johnson & Johnson vaccine, which is delivered in a single dose and does not require ultra-cold freezer storage, remains the most practical choice for many individuals.

Memorial Hermann will continue to comply with guidance from the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) and recommendations for the Johnson & Johnson vaccine, which now include a warning about the increased risk of very rare but severe blood clots.

While the chance of developing blood clots – or any adverse reaction – from the Johnson & Johnson COVID-19 vaccine is extremely rare, individuals should contact their healthcare provider if they develop serious symptoms in the days and weeks after being vaccinated. Symptoms of blood clots may include headache, blurred vision, fainting or loss of consciousness, loss of control over movement in part of the body, abdominal pain, shortness of breath, leg pain/swelling and seizures.

No. The COVID-19 vaccines do not affect DNA. The vaccines train the body’s immune system to recognize and fight the virus.

No. You do not have to show proof of residency to get a COVID-19 vaccine, and you do not need a Social Security number.

Yes. To ensure we have accurate information for your vaccine record, we will ask for your photo ID. Any of the following forms of identification will be acceptable as photo ID:

  • Driver's licenses or other state photo identity cards issued by Department of Motor Vehicles (or equivalent). We will accept current or expired identifications.
  • U.S. or foreign government-issued passport or identifications
  • A credit card with a photo
  • Employment or Student Identification card with photo

Yes. The Centers for Disease Control and Prevention (CDC) has recommended that pregnant women get a COVID-19 vaccine after research showed that the vaccine does not pose additional risks for mothers or babies. In addition, the CDC has stated the vaccines pose no risk for breastfeeding women or their babies. In fact, studies have shown that the COVID-19 vaccine provides protection to infants through breast milk.

Getting vaccinated, however, is a personal choice. If you are pregnant or breastfeeding, we encourage you to have a conversation with your healthcare provider to help you decide. In addition, according to the CDC, women younger than 50 years old should be aware of the rare but increased risk of blood clots with the Johnson & Johnson vaccine and may consider other COVID-19 vaccine options available for which this risk has not been seen.

Getting Vaccinated At Memorial Hermann

Yes, individuals who receive an invitation to schedule vaccination at Memorial Hermann can select a location for their appointment based on the vaccine being administered at that clinic, which will be noted next to the clinic name. Also, as Memorial Hermann begins to offer more walk-in vaccination opportunities, individuals will be informed upon arrival which brand of vaccine is available and can decide whether they wish to receive it.

In accordance with guidance from the State, all individuals 16 years of age and older are eligible for COVID-19 vaccination at Memorial Hermann. We encourage members of the community to complete Memorial Hermann’s COVID-19 Vaccination Request Form to register for vaccination.

The invitation you received cannot be used by another individual. We encourage your loved ones to register for vaccination by completing Memorial Hermann’s COVID-19 Vaccination Request Form. They will be notified when appointments are available for them.

When you scheduled your vaccination, you should have received an automated confirmation text message from (281) 214-6637 or email from MHVaccination@memorialhermann.org. If you cannot find your confirmation, please call Memorial Hermann’s COVID-19 Vaccine Helpline at (833) 772-2864.
