As hospitals and doctor’s offices work diligently to vaccinate our community as quickly as possible, we encourage everyone to:
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.
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.
Before any vaccine is widely distributed to the public, it is tested in clinical trials on tens of thousands of people to determine its safety and efficacy. While development and authorization of the COVID-19 vaccines were accelerated, this does not mean that safety corners were cut; the vaccines went through the same stringent testing process that other vaccines go through before public dissemination.
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.
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.
Effective March 29, 2021, the State of Texas is making the COVID-19 vaccine available to all adults. 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.
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.
Yes, individuals who receive an invitation to schedule vaccination can select a location for their appointment based on the vaccine being administered at that clinic.
In accordance with guidance from the State, all adults 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.
Memorial Hermann is actively working to expand our capacity and open additional appointments as we receive additional allocation of the COVID-19 vaccine. If you were invited to schedule a vaccination appointment but were unable to find available appointments, another invitation will be sent to you.
We strongly encourage you to keep your current appointment date and time. However, we understand circumstances can change. If you need to reschedule your appointment, locate the appointment confirmation that was sent to you via email from MHVaccination@memorialhermann.org and click on “Cancel My Appointment.” You will be able to reschedule after your initial appointment has been cancelled.
You do not need to take action to make sure your vaccination is registered. Memorial Hermann will report all vaccinations to ImmTrac2, the statewide immunization registry. That record will contain the details of your vaccination – the brand of vaccine you received, for instance, and when you receive the second dose – and it can be accessed later by medical professionals.
