Doses of the COVID-19 vaccine are currently being distributed right here in our community. The discovery of a vaccine gives us reason to celebrate as it provides a light at the end of the tunnel of the pandemic. Do you have questions about the vaccine? You aren’t alone. The Texas Department of State Health Services is your best resource for updates including when and where you can receive your vaccine.

We’ve also answered some of the most frequently asked questions about the vaccine below. Remember to always consult with your primary care provider to determine the best decision regarding your own health.

    Here’s what you need to know:

    Am I eligible to get the COVID-19 vaccine?

    UPDATE: The CDC, FDA, and Texas Department of State Health Services (DSHS) have recommended Pfizer’s COVID-19 vaccine for use in 12 to 15 year olds. Vaccine providers have been notified to begin administering the Pfizer vaccine to this age group.

    COVID-19 Vaccines for Children and Teens

    All COVID-19 vaccines are authorized for people age 18 and older. The Pfizer vaccine is the only vaccine currently authorized for people 12 and older.

    Reminder: Parental consent is required for the vaccination of children. Youth (ages 12-17) and parents should contact providers in their area to ensure they are offering the Pfizer vaccine before making an appointment or attending a walk-up vaccine clinic.

    Reminder: As more and more pharmacies and other providers begin to receive the vaccine, please visit DSHS to check vaccine availability near you.

    How much does the vaccine cost?

    The COVID-19 vaccine is provided at no cost.

    How does the vaccine work?

    Currently, the FDA has approved the COVID-19 vaccine developed by three manufacturers: Pfizer, Moderna, and Johnson & Johnson.

    Pfizer and Moderna:

    The Pfizer and Moderna vaccines use Messenger RNA (mRNA) technology. Essentially, using an mRNA vaccine, we trick our own cells into developing an immune response to COVID-19 which can protect us against a real infection in the future.

    There is NO live, weakened, or active coronavirus in the Pfizer or Moderna vaccine. You CANNOT get COVID-19 from the vaccine.

    • Both the Pfizer and Moderna vaccines are given in two doses. You need both doses of the vaccine for it to be fully effective.
    • It’s important to not mix and match vaccines. If you started with Pfizer, your second vaccination should be Pfizer. If you started with Moderna, your second dose should be Moderna.
    • Pfizer is recommended for ages 12 and up. Moderna is recommended for ages 18 and up.
    • Maximum protection will happen a few weeks after your second dose.

    To learn more about how mRNA vaccines – like the Pfizer and Moderna vaccine – work, visit CDC: Understanding and Explaining mRNA Vaccines. 

    Johnson & Johnson 

    The Johnson & Johnson vaccine is what’s known as a viral vector vaccine. It uses a harmless cold virus (NOT the coronavirus) to deliver a gene that instructs our cells to make a spike protein found in the coronavirus. This triggers production of antibodies and a resulting immune response, helping protect us against a real infection in the future.

    The virus used in the Johnson & Johnson vaccine poses no threat of causing illness in humans because it has been modified or, in some cases, because the type of virus used cannot cause disease in humans.

    • The Johnson & Johnson vaccine only requires a single dose.
    • The vaccine is recommended for ages 18 and up.
    • Maximum protection will happen a few weeks after you receive the vaccine.

    To learn more about how viral vector vaccines – like the Johnson & Johnson vaccine – work, visit CDC: Understanding and Explaining Viral Vector COVID-19 Vaccines.

    UPDATE: CDC and FDA recommend use of the Johnson & Johnson vaccine after a temporary pause. A review of all available data has shown that the Johnson & Johnson vaccine’s known and potential benefits outweigh it’s known and potential risks.

    However, women younger than 50 years old especially should be aware of the rare but increased risk of blood clots and low platelets. Look out for possible symptoms after receiving the vaccine, including: severe or persistent headaches or blurred vision, shortness of breath, chest pain, leg swelling, persistent abdominal pain, easy bruising, and/or tiny blood spots under the skin. There are other COVID-19 vaccine options available for which this risk has not been seen.

    What you need to know about Johnson & Johnson’s COVID-19 Vaccine

    Johnson & Johnson Q&As

    What are the possible side effects?

    Side effects reported include soreness at the injection site, fever, chills, headache, or muscle and joint pain. This is similar to reactions some people have to other vaccines, including flu and shingles.

    Have you experienced a side effect following COVID-19 vaccination? You can report it to VAERS. Anyone can submit a report to VAERS including parents and patients.

    I already had COVID-19. Do I still need to get the vaccine?

    Metro Health recommends that anyone who has had COVID-19 wait 90 days before receiving the vaccine. Your body will have created antibodies that should fight the disease if you were exposed again within this frame. Those same antibodies might also fight the vaccine.

    If you had COVID-19, it doesn’t mean that you’ll never get it again. The CDC recommends that you should get the vaccine regardless of whether you already had COVID-19 or not.

    What should I do if I contract COVID-19 between the first and second shot?

    If you contract COVID-19 during the waiting period between your first and second shot, you should quarantine/isolate and contact primary care physician. 

    Once are symptom-free and have completed the recommended quarantine period, you can receive the second dose of the vaccine. If the waiting period for your second shot has passed, you should get your vaccine as soon as possible.

    Get the second shot once you’re feeling better. You may still benefit from it and be better protected in the future.

    What do we know about the vaccine's safety?

    Several important steps were taken in the development of the COVID-19 vaccine:

    • Careful testing: The FDA approval process for the COVID-19 vaccine included rigorous standards including a four-phase process of volunteer trials. The FDA ONLY approves a vaccine if it’s safe and effective AND the benefits outweigh the risks.
    • Continuous monitoring: The FDA and CDC continue to monitor any problems or side effects experienced by those receiving the vaccine.

     Does the vaccine protect me from COVID-19 variants?

     Currently there are four notable variants in the United States: Alpha, Beta, Gamma, and Delta. These variants seem to spread more easily and quickly than other variants, which may lead to more cases of COVID-19. The Delta variant is expected to become the dominant coronavirus strain in the US, according to the director of the Centers for Disease Control and Prevention.

     So far, studies suggest that the current authorized vaccines work on the circulating variants. The Pfizer/BioNTech vaccine has shown to be 88% effective against symptomatic infections caused by the Delta variant, two weeks after the second dose. Moderna’s vaccine has also been found in lab experiments to work against new variants such as the Delta strain.

    I got my COVID-19 vaccine! What happens next?

    Priti Mody-Bailey, MD, Community First Health Plans Chief Medical Officer, explains what to expect as more and more people receive the COVID-19 vaccine.

    I got my vaccine! Can I still get sick from COVID-19?

    Yes, but it’s much less likely. Based on evidence from clinical trials, the vaccine was 95% effective at preventing COVID-19 illness in people who had not been previously infected. If you do get infected, you will likely experience milder symptoms.

    Do I still have to wear my mask and social distance even after I get the vaccine?

    Yes. Texas will need millions of vaccines for all who want one, and the vaccine process takes a month or longer for maximum protection.

    Experts are still learning about the protection the vaccine provides under real-life conditions. Everyone needs to continue using all the tools available to help stop this pandemic, including:

    • wearing a mask,
    • practice social distancing,
    • and washing your hands often.
    Now that the vaccine is available, how long will it take for the pandemic to end?

    For the pandemic to end, we need to achieve herd immunity. Herd immunity is a term used to describe when enough people have protection—either from previous infection or vaccination—that it is unlikely a virus or bacteria can spread and cause disease. As a result of herd immunity, everyone within the community is protected, even if some people don’t have any protection themselves.

    Experts do not know what percentage of people need to get vaccinated to achieve herd immunity to COVID-19. Although the vaccine appears to be very effective, we need to learn more about the protection it offers before stopping other prevention steps we’ve adopted during the pandemic.

    Will I need to get the COVID-19 vaccine every year, like the flu shot?

    We won’t know how long immunity lasts until we have more data on how well the vaccine works. Current evidence suggests that reinfection with the virus that causes COVID-19 is uncommon in the 90 days after the initial infection. Both natural immunity and vaccine-induced immunity are important aspects of stopping COVID-19 that experts are trying to learn more about.
