Vaccine Frequently Asked Questions (FAQs)
COVID-19 illness can have serious and life-threatening complications and there is no way of knowing how COVID-19 will affect you. The current COVID-19 vaccines have been shown to be highly effective (95%) at preventing COVID-19 and lowering the risk of serious illness or death.
COVID-19 vaccinations are an important tool to help stop the pandemic by lowering the number of COVID-19 cases in the U.S. and preventing further transmission (herd immunity). In addition, the more people vaccinated against COVID-19, the better chance we have of not developing new variants of the COVID-19 virus that the vaccines may not be as effective against.
- Herd immunity occurs when enough people become immune to a disease to make its spread unlikely.
- Herd immunity is achieved by protecting people against a virus not exposing them to a virus.
- It is estimated we need at least 70% of the U.S population with immunity to reach herd immunity from COVID-19 (231 million people)
- To reach herd immunity through natural infection with COVID-19 would cause healthcare systems to be overwhelmed and cause unnecessary deaths and lifelong disabilities.
In the past, some vaccines have taken years to develop. However, there are several reasons we were able to develop safe and effective vaccines against the virus causing the COVID-19 pandemic:
- The mRNA technology used to develop COVID-19 vaccines has been in development for many years to prepare for outbreaks of infectious viruses. Therefore, the manufacturing process was ready very early in the process.
- Governments around the world gave enough money to vaccine developers, so they had the resources needed to develop and conduct trials on the vaccine quickly.
- Because the SARS-CoV-2 coronavirus is so contagious and widespread, many of the volunteers in the clinical trials were exposed to the virus so the trials took a shorter time to see if the vaccine worked.
- Social media enabled companies to reach out to enroll volunteers and there were many people willing to enroll in the clinical trials.
Researchers have been studying mRNA vaccines for decades, this is not new science.
- The COVID-19 vaccines DO NOT change your DNA because the mRNA does not enter the cell nucleus where DNA is found.
- mRNA vaccines do not contain live viruses and, therefore, cannot infect someone with COVID-19.
- mRNA vaccines do not contain eggs, latex or preservatives.
- mRNA vaccines do not have the ability to cause cancer.
The vaccines contain synthetic mRNA, which is genetic information used to make the SARS-CoV-2 spike protein. The spike protein is the part of the virus that attaches to human cells. The spike protein alone cannot cause COVID-19. Once you are vaccinated, the mRNA will instruct your cells to produce the spike protein and your immune system will recognize the spike protein as different and make antibodies to protect you from acquiring and/or getting very sick if you come in contact with COVID-19.
Viruses constantly change through mutation and new variants are expected to occur over time.
The most dominant variants of the virus that causes COVID-19 are now circulating globally. These variants are found to spread more easily and quickly than the original virus.
- United Kingdom:
- UK variant B.1.1.7: Detected in U.S. December 2020
- Spreads more easily and may be more deadly than other variants.
- South Africa:
- Variant B.1.351: Detected in October 2020 and in U.S. Jan 2021
- Variant P.1: Detected in U.S. in January 2021
So far, studies suggest that antibodies generated through current vaccines are effective against these variants, but this is still being investigated and studied. What we do know: The more people who are vaccinated, the less opportunity for the COVID-19 virus to mutate and develop more variants that may be resistant to our current vaccines.
It is currently unknown how long natural immunity lasts after recovering from COVID-19. Early studies show that it is not long lasting, and cases of reinfection have been reported.
Due to the severe health risks associated with COVID-19, it is recommended that a person who has had COVID-19 be vaccinated. If you have received monoclonal antibody treatment for your COVID-19 infection, you must wait 90 days to receive the vaccine. Otherwise, you may receive the COVID-19 vaccine if it has been at least 14 days since symptom onset and most symptoms have resolved.
There is no evidence that the COVID-19 vaccine causes infertility or interferes with placenta formation. 18 women became pregnant during the clinical trials and not problems with their pregnancy were reported. Current recommendations say there is no reason to delay conception after being vaccinated.
Persons under fertility treatments may get vaccinated. If you become pregnant after the first dose of COVID-19, you should not delay the second dose. Speak to your healthcare specialist about your concerns so you may make an informed decision.

Coronavirus Frequently Asked Questions (FAQs)
While the CDC has determined that the current risk of infection of COVID-19 in the United States remains low, there are steps you can take to stay healthy, such as:
- Wash your hands frequently and for at least 20 seconds with soap and water or alcohol-based hand sanitizer.
- Cough into your elbow or a tissue and not your hands. Dispose of the tissue.
- Clean and disinfect frequently touched surfaces at home, work and school.
- Avoid touching your eyes, nose and mouth.
- Avoid close contact with people who are sick.
- If you are sick, stay home and do not travel or report to work.
- Practice healthy habits: Get plenty of sleep, be physically active, manage your stress, drink plenty of fluids and eat nutritious food.
If you have a fever and/or respiratory symptoms AND have traveled internationally or across states, OR have been in contact with someone diagnosed with COVID-19, please contact your county health department for direction about testing and treatment. The health department will advise you on how to access care if needed and will contact your local hospital.
