Q. Are there any reasons I should wait to have the vaccine?
A. There are a few reasons why you may need to wait to receive a vaccine:

  • If you currently have COVID-19 or COVID-19 symptoms
  • If you are quarantined because of an exposure to COVID-19
  • If you have received Monoclonal Antibody Therapy or Convalescent Plasma in the past 90 days

Q: Can COVID-19 vaccine be given to pregnant or breastfeeding women?
A. Yes. It is recommended that all pregnant individuals be vaccinated against COVID-19. Infection with COVID-19 puts pregnant people at increased risk of complications and death. Evidence about the safety and effectiveness of COVID-19 vaccination during pregnancy is increasing, and indicates that the benefits of receiving a COVID-19 vaccine outweigh any known or potential risks of vaccination during pregnancy.

Q. Will it cost anything to receive the vaccine?
A. Most private insurance companies and government insurance programs like Medicare will fully cover the cost of the vaccine. For those who are uninsured, you will be billed for the cost of receiving the vaccine (prior to April 5, 2022, vaccines were covered by HRSA for uninsured patients, but this coverage has now lapsed).

Q. How do I replace a lost or damaged CDC vaccination card?
A. If your CDC COVID-19 Vaccination Record card is misplaced or damaged, staff can issue you a replacement at your Vaccine appointment. They will verify your vaccination by referring to your medical record or department of health vaccine registries. For more information or to request a new card, call 218.249.4200.

Q. When will I need a COVID vaccine booster shot?
For the latest, check the CDC's website on staying up-to-date with your COVID-19 vaccines here.

Vaccine Effectiveness

Q. When will I have protection from COVID-19 after the vaccines?
A. It takes time for your body to build protection after any vaccine. COVID-19 vaccines that require 2 shots may not protect you until 1-2 weeks after the second shot. Studies have shown that vaccine efficacy may decrease over a longer period of time, which is why boosters are recommended.

Q. Can the COVID-19 vaccine give me a COVID-19 infection?
A. No, none of the vaccines that St. Luke’s is using contain a live COVID-19 virus.

Q. What are the risks of not getting vaccinated?
A. While many people who get COVID-19 have only a mild illness, others may get a severe illness or they may even die. There is no way to know how COVID-19 will affect you, even if you are not at increased risk of severe complications. If you get sick, you also may spread the disease to friends, family and others around you.

Q. How can I protect myself from getting COVID-19 before I can receive the vaccine?
A. You should continue to follow CDC and department of health recommendations to decrease your risk of acquiring COVID-19 through methods like covering your nose and mouth with a mask when around others outside of your household, avoiding close contact with people who are sick, staying at least 6 feet away from others, avoiding crowds and washing your hands frequently.

Vaccine Side Effects

Q. What are the common responses to the COVID-19 vaccine?
A. You may have some minor side effects, which are normal signs that your body is building protection. The common responses to these vaccines are: pain or swelling in the arm where you got your shot, fever, chills, fatigue, headache, muscle aches, and joint aches. These are typically mild to moderate and generally resolve within 1-2 days. Responses for multi-dose vaccines are more common after the follow-up dose(s), and are more frequent and severe in 18-55 year olds than those greater than 55 years.

Cough, shortness of breath, a runny nose, sore throat, loss of taste or smell are NOT consistent with post-vaccination symptoms.

Q. Is it safe to get the second shot of Pfizer or Moderna if I had a reaction to the first dose?
A. Yes, you should get the second dose even if you had side effects from the first dose, unless a vaccine provider or your doctor tells you not to get a second shot. When you go in for your second dose, be sure to let the vaccinator know what side affects you had.

Q. Will the vaccine cause sterility or infertility?
A. Social media articles have circulated regarding the vaccine’s potential impact on infertility. However, the claims are not based on any reliable scientific evidence. There is no scientific evidence from the current studies that the SARS-CoV-2 vaccine causes infertility in men or women.

Vaccine for those who had COVID-19 or are feeling ill

Q. If I have already had COVID-19 and recovered, do I still need to get vaccinated?
A. Yes. There is not enough information currently available to say if or for how long after infection someone is protected from getting COVID-19 again (called natural immunity). Early evidence suggests natural immunity from COVID-19 may not last very long, but more studies are needed to better understand this. Since natural immunity is known to be good for at least 3 months after contracting COVID-19, those who were previously infected with COVID-19 can elect to delay their vaccine up to 90 days from their positive test if they so choose.

You should be well, fever-free and not in an isolation or quarantine period when you get your COVID-19 vaccine. Those who received Monoclonal Antibody Therapy or Convalescent Plasma treatment must wait 90 days to receive the vaccine.

Q: Why should I be vaccinated if I have already had COVID-19? Am I not immune?
A. There is risk of reinfection after having COVID-19, especially with more contagious variants. By receiving a vaccine after having COVID-19 infection, your immune system gets a boost in protecting you from repeat infection.

Q. Do I have to be symptom-free to get the vaccine?
A. Like any other vaccine, you don’t want to have a fever or obvious illness because your immune system is already working to fight something off. In addition, you won’t know what side effects you’re having from the vaccine. You should defer your date until you’re feeling better.

Q. If I get the COVID-19 vaccine and take a COVID-19 test, will it come back positive?
A. No, the vaccine will not cause you to test positive on a COVID-19 test. If/when your body develops an immune response, which is the goal of vaccination, there is a possibility you may test positive on an antibody blood test.

Reasons to get the vaccine

Q. Why is a vaccine needed if we can do other things, like social distancing and wearing masks, to prevent the virus from spreading?
A. Stopping a pandemic requires using all available tools. Vaccines work with your immune system so your body will be ready to fight the virus if you are exposed. Other steps, like covering your mouth and nose with a mask and staying at least 6 feet away from others, help reduce your chance of being exposed to the virus or spreading it to others. Together, COVID-19 vaccination and following the CDC’s recommendations on how to protect yourself and others will offer the best protection from COVID-19.

Q. Should I continue to wear a mask and avoid close contact with others if I am up-to-date on the vaccine?
A. The Centers for Disease Control and Prevention (CDC) has published interim public health recommendations for fully vaccinated people. Learn more.
