Yes. The COVID-19 vaccines have undergone rigorous safety testing. Scientists from the FDA and the Centers for Disease Control (CDC) have reviewed all information from the testing process and determined the vaccine to be safe.
All the usual steps have been taken to make sure the COVID-19 vaccines are safe. To speed up the development of the COVID-19 vaccine, drug manufacturers built upon previous research, used new and faster methods, and was able to begin making the vaccine in advance.
Experts continue tracking vaccine safety information once vaccines are given in real-life conditions to make sure they are working as expected.

Frequently Asked Questions about COVID-19 Vaccination | CDC
The most common side effects from the COVID-19 vaccines are mild and temporary. They include fatigue, headache, and muscle aches. You may experience some or none of these side effects. When mild side effects occur, they are a normal sign your body is building protection to the virus. If these minor side effects occur, it’s most likely a day or two after getting the vaccine, and go away in a few days. It is more common to experience these side effects after the second dose.
Because a very small percentage of people who’ve received the vaccine have experienced an allergic reaction, individuals are asked to wait for 15-30 minutes at the vaccination site to be monitored by medical staff so they could be treated if necessary.
Possible Side Effects After Getting a COVID-19 Vaccine | CDC
The Pfizer and Moderna vaccines are mRNA vaccines and requires two doses. You will get one shot, and then a second shot at least 21-28 days later (depending on if the Pfizer or Moderna vaccine is used.) It is necessary to get both doses of the same vaccine to be fully protected. These vaccines do not contain any live or dead COVID-19 virus. Instead, it uses spike protein RNA, which teaches the immune system to recognize the COVID-19 virus and destroy it before it can infect you.
The Johnson & Johnson vaccine is a viral vector vaccine. This means it uses a modified version of a different, harmless virus to deliver important instructions to our cells. It then use the cell’s machinery to produce one COVID-19 virus protein known as spike protein. The spike protein is found on the surface of the virus that causes COVID-19. After vaccination, you body's immune system recognizes this protein and blocks the virus from infecting you.
The CDC recommends those starting their primary series or getting boosters get Pfizer or Moderna, (though Johnson & Johnson may still be used in certain situations.) You should receive the same mRNA vaccine product for both doses of a two dose primary series. You may use a different vaccine product for your booster than you received for your primary series.

An employer may require that their workers be vaccinated. Check with your employer to see if they have any rules that apply to you.
We strongly encourage you to get the COVID-19 vaccine. Getting vaccinated helps protect you and your family, co-workers, residents, patients, and community.
Your vaccination status is your personal data and providers are not able to provide this information to others. However, this information will be available to you to provide to others as proof of vaccination, should an employer or others require this and you are willing to provide your personal vaccination history. No one else is legally able to access your personal vaccination data.
Like all personal health information, COVID-19 vaccination status is protected by federal and state law. Your COVID-19 vaccination status will be entered into the Minnesota Immunization Information Connection. You will also get a card documenting that you received the COVID-19 vaccine.
Some employers, business, and entertainment venues require proof of vaccine as do certain modes of transportation (certain airlines) and in order to enter some foreign countries. The white COVID-19 Vaccination Record Card that you received at the time of vaccination is proof that you were vaccinated. You can also request your vaccination records from MDH: Find my Immunization Record . Another way to access your immunization records is to download the Docket app from the App store or Google Play
You should get a COVID-19 vaccine even if you already had COVID-19.
Getting a COVID-19 vaccine after you recover from COVID-19 infection provides added protection to your immune system. People who already had COVID-19 and do not get vaccinated after their recovery are more likely to get COVID-19 again than those who get vaccinated after their recovery.
All COVID-19 vaccines currently available in the United States are effective at preventing COVID-19. Getting a COVID-19 vaccine gives most people a high level of protection against COVID-19, even in people who have already been sick with COVID-19.
There is no evidence the vaccine can cause sterility or infertility. There is also no biological mechanism that would lead to sterility or infertility in COVID-19 vaccine recipients. This myth originated from unscientific sources and hypotheses not supported by scientific fact.
COVID-19 Vaccines for People Who Would Like to Have a Baby | CDC
A booster is recommended for everyone ages 12 years and older after they have completed their COVID-19 vaccine primary series. Children ages 12 to 17 years old can only get the Pfizer-BioNTech COVID-19 booster shot. Adults age 18+ should get a booster dose, and either Pfizer-BioNTech or Moderna (mRNA COVID-19 vaccines) are preferred.
No. The COVID-19 vaccine is a messenger RNA (mRNA) vaccine. The mRNA in these vaccines directs the production of specific proteins that your immune system will recognize as viral proteins and subsequently generate a protective immune response. Neither the mRNA nor protein has the ability to change your genome and does not enter the nucleus, where the DNA is located.
No. This is myth that has circulated on the internet. The COVID-19 vaccine is safe and effective and can prevent you from getting a severe case of COVID-19.
St. Louis County Public health, like all public health agencies, provides unbiased information and resources to residents of the county we serve. COVID-19 vaccines have been produced by non-governmental private companies, and the safety and effectiveness of these vaccines has been monitored by an independent monitoring board. In addition, public health experts at universities, and medical and pharmacy practitioners have uniformly recommended COVID-19 vaccinations for all eligible populations to combat this deadly disease.
We encourage you to check with your health care provider to ensure you are getting accurate and up-to-date vaccine information from a credible source.
