Frequently Asked Questions about the COVID-19 vaccine
What is the Pfzer-BioNTech COVID-19 Vaccine?
The Pfzer-BioNtech product is a vaccine authorized under emergency use that may prevent you from getting COVID-19. Because this is an emergency utilization of the vaccine, this product has not been granted full approval yet. This means the Food and Drug Administration (FDA) has determined at this time the benefits of this vaccine outweigh the risks when administered to persons who are 16 years of age or older. You are encouraged to read the full Emergency Use Authorization (EUA).
How is the vaccine given?
The vaccine is given via an intramuscular injection (shot) into your deltoid (shoulder) muscle.
How does this vaccine work? Will it affect my DNA?
This vaccine works by sending messenger RNA (mRNA) into your muscle with instructions to your immune cells to stimulate an immune response (protection) against COVID-19. It teaches your body how to make a protein that triggers antibody production so if the real virus enters your body at a later date, your immune cells will recognize it and protect you against it.
It does not enter the part of your cell where your DNA is found (the nucleus) and therefore will not change or alter your DNA.
Will this vaccine give me COVID-19?
No, this is not a live vaccine and will not give you COVID-19. The vaccine does not contain SARSCoV2 and cannot give you COVID-19.
Is this vaccine effective in preventing COVID-19?
Yes, according to the latest trial information, the Pfzer-BioNtech vaccine is 95 percent effective in preventing COVID-19 infection. The vaccine requires two injections 21 days apart to give you protection.
Do I have to get the second (booster) vaccine?
Yes, in order to provide you with immunity (protection), the Pfizer vaccine requires a second injection 21 days after the first dose. The manufacturer recommends that you adhere as close to the 21 day period as possible +/- 2 days.
How long does the vaccine last?
The exact duration is unknown at this time; however, information suggests the vaccine is effective for at least 3 months.
If I get the vaccine, do I still have to wear a mask?
Yes, even if you take the COVID-19 vaccine, you should follow masking guidelines and maintain social distancing.
Is the shot painful?
You may experience redness and/or muscle pain at the site of injection.
What are the most common side effects? What are the serious side effects?
Pain at the injection site, tiredness, headache, muscle pain, chills, joint pain and fever are the most common side effects and should resolve in 2-3 days. Most people will experience more of these side effects following the administration of the second injection. It is important that recipients prepare and expect for potential side effects when receiving the vaccine.
Rarely, severe allergic reaction may occur within minutes up to an hour of receiving the vaccine. Signs of severe allergic reaction include difficulty breathing, swelling of the face and throat, increased heart rate, rash and dizziness. There may be other serious and unexpected side effects as this vaccine is still being studied in clinical trials.
What do I do if I am experiencing adverse side effects after taking the vaccine?
If you are experiencing severe or life threatening side effects, please seek emergency care or call 911. Otherwise, please seek medical care. You will also receive information at the time of vaccination regarding how to report side effects, including utilizing the CDC’s V-safe app, as well as how to use the Vaccine Adverse Events Reporting System.
Is the vaccine safe for pregnant women or women planning to become pregnant?
Pregnant women and women planning pregnancy in the next two months may choose to get the vaccine; however, they should discuss the vaccine with their healthcare provider first in order to ensure they are well-informed about the potential risks and benefits.
Is the vaccine safe for nursing mothers?

Immunocompromised persons can choose to receive the vaccine; however, they should discuss the risks and benefits with their healthcare provider first.
Am I still eligible to receive the vaccine if I tested positive for COVID-19 in the past?
People should get the COVID-19 vaccine regardless of prior symptomatic or asymptomatic COVID-19 infection. If you are currently diagnosed with COVID-19, you should wait until you have recovered from illness and can discontinue isolation (at least 10 days from symptom onset and 24 hours without fever).
Can I take the COVID-19 vaccine if I am currently sick or have COVID symptoms?
No, you will need to be free of sick symptoms, including fever, in order to be vaccinated. Temperatures will be checked at the time of vaccination and anyone with a fever will not be vaccinated.
Can I infect others with COVID-19 if I have been vaccinated?
This is unknown. Therefore, at this point we only know it protects the person getting the vaccine from getting disease symptoms. We do not know if this vaccine stops virus transmission. You should still follow universal masking and practice social distancing even with vaccination at this time.
Can I get the COVID vaccine if I recently received another vaccine, or am planning to receive another vaccine within 14 days?
The COVID-19 vaccine should not be administered at the same time as any other vaccine. A minimal interval of 14 days before or after administration with any other vaccine, including flu shots, should occur prior to COVID-19 vaccine administration.
