Understanding the COVID19 Vaccines

When the novel coronavirus pandemic began, vaccine trials quickly followed to aid in the fight against COVID-19 in our communities. Most recently, the Pfizer and Moderna vaccines received approval for emergency use authorization from the U.S. Food and Drug Administration (FDA).

While this is exciting, hopeful news, it’s understandable that you may have many questions regarding the new vaccines, just as you did when first learning of the novel coronavirus. Here’s a brief overview of what we know about the COVID-19 vaccines, and more information can be found here.


What is the vaccine distribution plan?

The Texas Department of State Health Services guiding principles for vaccine distribution use a phased and tiered approach. Vaccine distribution will be prioritized by:

  • 1A Direct Care: Hospital, Long-Term Care, EMS, Home Health, Outpatient, ER/Urgent Care, Pharmacies, Last Responders, School Nurses
  • 1A Long-Term Care: Residents of long-term care facilities
  • 1B Persons: Individuals age 65+ or 16+ with at least one chronic medical condition (e.g. cancer, COPD, certain heart conditions, sickle cell disease, obesity, etc., and including pregnancy). For more information, visit texas.gov.

Can I sign up on a waitlist for a COVID-19 vaccine?

Yes, North Texans can sign up through their county health department website (CollinDentonDallasTarrant). Information for additional counties is located on the state Health and Human Services website. As vaccine supply becomes more readily available, access will increase. Texas Health is a community vaccination hub provider for Tarrant County only. If you are a Tarrant County resident, be sure txo sign up here. State vaccine information is available here.

As available, vaccines will also be distributed through Texas Health primary care offices across North Texas. Following the tiering determined by the state of Texas, the current focus is vaccination for Phase 1A and 1B individuals. Texas Health Family Care, Texas Health Internal Medicine, and Texas Health Adult Care patients should watch for messages about the vaccine from their doctor.  These Texas Health primary care practices will be working to vaccinate patients as quickly as possible. Patients do not need to sign up for the vaccine or call the office as physicians already have contact information.

Vaccinations are available by appointment only, regardless of whether you are obtaining your shot via the county health department or through your physician’s office and are not available at hospitals or physician offices on a walk-in basis.


How were the vaccines tested?

Clinical trials are evaluating investigational COVID-19 vaccines in tens of thousands of study participants to enable the U.S. Food and Drug Administration to determine safety and effectiveness. These clinical trials are being conducted according to the FDA’s rigorous standards.

The trials are conducted in three phases:

  • In phase 1, the vaccine is given to a small number of generally healthy people to assess its safety at increasing doses and to gain early information about how well the vaccine works to induce an immune response in people.
  • Phase 2 studies include more people with varying health statuses and from different demographic groups receiving various dosages. These studies provide additional safety information and may provide initial information regarding the effectiveness of the vaccine.
  • In phase 3, the vaccine is administered to thousands of people in randomized, controlled studies involving broad demographic groups. In a randomized, controlled study, individuals are assigned at random to receive the vaccine and are compared against those in the study who did not receive the vaccine. Study participants do not know if they are receiving the vaccine or the placebo in order to ensure accurate information, critical information on the effectiveness and additional important safety data. It provides additional information about the immune response in people who receive the vaccine compared to those who receive a control, such as a placebo. (FDA)


What are the side effects of the vaccine?

Moderna has reported that some trial participants had “severe” side effects, and others had to slow down on their daily activities for a few days. Significant side effects from the first dose included injection site pain, but more felt worse after the second dose — reporting fatigue, muscle and joint pain, and headache, among other symptoms. In the Pfizer trial, participants reported fatigue and headaches after getting the second dose. (The Washington Post, Pfizer and Moderna news releases)

If symptoms worsen or do not go away after one week, contact your primary care physician and seek medical attention.


If I’ve already had COVID-19, would the vaccine be helpful?

Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, people may be advised to get a COVID-19 vaccine even if they have been sick with COVID-19 before.

At this time, experts do not know how long someone is protected from getting sick again after recovering from COVID-19. The immunity someone gains from having an infection, called natural immunity, varies from person to person. Some early evidence suggests natural immunity may not last very long.

People who are known COVID-19 positive should wait to receive the vaccine until they are symptom free and no longer require isolation. For most people this is 14 days with no signs or symptoms. People who have had COVID-19 may want to check with their primary care provider to see when it is OK to start their vaccines.


The Takeaway

It’s natural to have questions, fears or apprehensions about a new vaccine, just as we all did at the beginning of this year as the novel coronavirus spread globally. We hope the information provided here helps answer your questions and helps you make the best decision for you and your family’s health.

While vaccines are currently being sent out and the first groups of recipients are beginning to receive them, it’s important to remember that the fight is not over yet; we must remain vigilant when it comes to social distancing, hand hygiene, mask-wearing and other important health measures until everyone who would like to receive the vaccine can get one.
