I'm a Doctor and Warn You Don't Believe These COVID Myths

Here are some of the most high-profile vaccine myths, busted. 

Since the start of the COVID-19 pandemic, there have been endless myths surrounding the virus that have spread – especially surrounding the vaccines. "COVID-19 vaccines are safe, effective, and free. Everyone 6 months and older can get an updated COVID-19 vaccine," explains the Centers for Disease Control and Prevention. Obviously, getting vaccinated is a personal choice. But if you are hesitant to get the jab based on the information you have heard surrounding the potential dangers, it's essential to separate the facts from the myths. We asked Covid expert Darren Mareiniss, MD, FACEP emergency medicine physician, to bust a few of the most high-profile COVID myths swirling around. 

Myth 1: The COVID-19 Vaccine Can Affect Women's Fertility

Are you worried that getting the vaccine may impact your chances of getting pregnant? "This is not correct," says Dr. Mareiniss. "There have been studies regarding fertility that specifically debunk this myth. "

Myth 2: If I've Already Had COVID-19, I Don't Need a Vaccine


Dr. Mareiniss maintains this is another "incorrect" belief. "Data demonstrates significantly improved protection from severe disease when vaccinated as compared to simply previously having COVID. In addition, as the variants change, vaccines are being modified to improve immune defenses. So, as the virus changes, the vaccine can provide protection that prior infection does not provide," he says. 

Myth 3: Researchers Rushed the Development of the COVID-19 Vaccine, So its Effectiveness and Safety Cannot Be Trusted

This is simply not true, says Dr. Mareiniss. "The mRNA covid vaccine has gone through extensive testing large scale study and passed rigorous FDA evaluation. By all accounts, it's one of the most tested (if not the most tested) vaccines in the history of the FDA. Also, we continue to accumulate aftermarket data on millions of individuals that have received the vaccines," he says. 

Myth 4: Getting the COVID-19 Vaccine Means I Can Stop Wearing My Mask and Taking Coronavirus Precautions


Getting the vaccine doesn't mean you shouldn't wear a mask. "The vaccine protects recipients from death and severe disease. It is not a shield and will not prevent infection," says Dr. Mareiniss. "If warranted by disease prevalence, masking can prevent infection."


Myth 5: Getting the COVID-19 Vaccine Gives You COVID-19

No, getting vaccinated won't give you the virus. "The COVID-19 vaccine simply creates an immune response to specific virus proteins. It protects you from covid. It does not and cannot give you covid," says Dr. Mareiniss.

Myth 6: The Side Effects of the COVID-19 Vaccine Are Dangerous


"As compared to infection with COVID-19, the risk of the vaccine is minimal and clearly justified," attests Dr. Mareiniss. "Vaccinated individuals are clearly less likely to die of Covid-19 infection than non-vaccinated individuals. Also, vaccination does not increase death by non-covid-related causes. The most significant COVID-19 mRNA vaccine side effect is anaphylaxis (very severe allergic reaction). This is very rare (5 per 1,000,000 vaccine doses), and we screen for this among everyone who receives the vaccine. There are also very rare reports of myocarditis/pericarditis after vaccination. This has been seen predominantly in males in their late teens and early 20s. Even within this group, it is an extremely rare occurrence (4.9 per 100,000 doses by a Moderna study), and the few patients identified typically fully recover."

Myth 7: The COVID-19 Vaccine Enters Your Cells and Changes Your DNA


Again, this is not true. "The mRNA uses your cellular ribosomes to create a viral protein that your body's immune system identifies. The mRNA does not and cannot alter your DNA," says Dr. Mareiniss. 

Myth 8: The Messenger RNA Technology Used to Make the COVID-19 Vaccine Is Brand New


Again, this is another fallacy surrounding the vaccine. "We've had this technology for a long time," Dr. Mareiniss confirms.

Myth 9: The COVID-19 vaccine Was Developed With or Contains Controversial Substances


This is simply not true, says Dr. Mareiniss. There are no controversial substances in the vaccine.

Myth 10: Now That We Have a Vaccine for COVID-19, We Can Make Vaccines for the Common Cold, HIV and Other Diseases


Dr. Mareiniss calls the mRNA technology "a huge step forward in vaccine developments," however, he doesn't expect a vaccine for the common cold. "There are hundreds of viruses that can cause cold symptoms (e.g., adenovirus, rhinovirus, RSV… etc)," he points out.
