Fact or Fiction? COVID-19 Vaccine Myths Debunked


*Written by Dr. Shalaunda Gray, Medical Director at Lakemary Center

Lakemary’s Medical Director, Dr. Gray, and our Nurse Practitioners, Sara & Megen, debunk several common myths about the COVID-19 vaccines

Dr. Gray explains how it benefits every Lakemary staff member to get the vaccine.

Myth 1: We can’t trust COVID-19 vaccines because they were rushed.

The first vaccines for COVID-19 do involve new technology, and they were developed in record time. But it’s not because there were shortcuts in the process.

The new technology at the center of Pfizer’s and Moderna’s COVID-19 vaccines is called messenger RNA, or mRNA. While this is the first time it’s being widely used in a vaccine for the public, researchers have actually been working on this vaccine strategy for more than three decades.

The companies put their vaccines through rigorous clinical trials involving tens of thousands of volunteers. In the U.S., the Food and Drug Administration requires them to follow up with volunteers for up to two years after receiving the vaccines to make sure they are safe and effective.

Because of how prevalent COVID-19 is, it only took a few months for the clinical trials to collect enough data to make an initial evaluation. The FDA, as well as an independent panel of vaccine experts, closely scrutinized the data from those trials and deemed Pfizer’s and Moderna’s vaccines safe and effective for emergency use. Similar independent panels in several other countries are in agreement.

Myth 2: The vaccine will give me COVID-19.

Vaccines prime your immune system to recognize and fight off a disease, but they don’t actually cause an infection.

The first two COVID-19 vaccines that are available in the U.S. contain a strand of genetic material called mRNA. When the mRNA enters your cells, it instructs them to make a piece of the “spike” protein that’s present on the coronavirus that causes COVID-19. Those protein pieces don’t actually harm your body, but they do trigger your immune system to mount a response to fight them off.

You might have some fatigue, muscle aches, a headache or a fever after you get the vaccine. That’s normal with any vaccine – it’s a sign that your immune system is responding.

Myth 3: We don’t know what’s in these vaccines.

Both Pfizer and Moderna have published the ingredient lists for their vaccines. In addition to the star ingredient, the COVID-19 mRNA for the spike protein, both vaccines contain lipids (fats) that help deliver the mRNA into your cells and a few other common ingredients that help maintain the pH and stability of the vaccine. Despite theories circulated on social media, they do not contain microchips or any form of tracking device.

Dr. Gray specifically addresses the myth that there is a microchip from the government in the COVID-19 vaccine.

Myth 4: These vaccines will alter my DNA.

The vaccines use mRNA to instruct our cells to make a piece of the coronavirus’s hallmark spike protein in order to spark an immune system response. Once the mRNA does that, our cells break it down and get rid of it.

Messenger RNA is something that’s made from DNA, but it’s not designed to integrate with our DNA, and it doesn’t permanently change our genome and who we are in any way.

Myth 5: I already had COVID-19, so I won’t benefit from the vaccine.

We don’t yet know how long natural immunity to COVID-19 lasts. Right now, it seems that getting COVID-19 more than once is not common, but can occur. There are still many questions that remain unanswered. Experts from CDC say that, even if you’ve had COVID-19, it would still be appropriate for you to get the vaccine to make sure you’re protected.

Late stage clinical trial data suggested the vaccine was safe and helped protect people with past Covid-19 infections from reinfection. This was regardless of their past case being mild or severe.

A person who is currently sick with Covid-19 should, however, wait to get the vaccine after their symptoms have cleared up and they can come out of isolation. There’s no recommended minimum time between infection and vaccination.

Myth 6: Since COVID-19’s survival rate is so high, I don’t need a vaccine.

It’s true that most people who get COVID-19 are able to recover. But it’s also true that some people develop severe complications. So far, more than 1.7 million people around the world have died from COVID-19 – and that doesn’t account for people who survived but needed to be hospitalized. Because the disease can damage the lungs, heart and brain, it may also cause long-term health problems that experts are still working to understand.

There’s another reason to consider getting the vaccine: It protects those around you. Even if COVID-19 doesn’t make you very sick, you could pass it on to someone else who might be more severely affected. Widespread vaccination protects populations, including those who are most at risk and those who can’t be vaccinated. It will be important for ending the pandemic.

Myth 7: Once I get the vaccine, I won’t have to wear a mask or worry about social distancing.

Even if you get the vaccine, you should continue to wear a mask around others, wash your hands and practice physical distancing. There are a few reasons for this. The first is that both of the authorized vaccines require two doses given three to four weeks apart to achieve the best possible immunity.

When you get your first shot, you don’t become immediately immune. It takes at least a week to 10 days for your body to begin to develop antibodies, and then those antibodies continue to increase over the next several weeks.

 The second is that these vaccines were developed and tested for their ability to prevent severe illness and death from COVID-19. It’s not clear whether they also protect against asymptomatic infection and spread.

There will be ongoing studies to evaluate this question, but it will be some time before we actually know. So after you get the vaccine, you should still take steps to protect other people who haven’t been vaccinated yet.

Myth 8: Now that we have vaccines, the pandemic will be over very soon.

I would love to say that we’re going to flip a switch and everything’s going to be back to normal, but it’s actually going to take a long time for us to be able to vaccinate an adequate number of people to where we’ll start to see the cases really dropping.       

In order to achieve what’s called herd immunity – the point at which the disease is no longer likely to spread – about 70% of the population will need to have been vaccinated or infected, he says. But the companies that make these vaccines can only make so many at a time. So the vaccines will be distributed in phases, with priority given to people with greatest need. They may not be widely available to the general public until several months into 2021.

For now, we should all continue to do our part to help slow the spread of the virus, including wearing a mask, washing our hands and physical distancing.
