COVID-19 Vaccinations

No. None of the authorized and recommended COVID-19 vaccines or COVID-19 vaccines currently in development in the United States contain the live virus that causes COVID-19. This means that a COVID-19 vaccine cannot make you sick with COVID-19.

There are several different types of vaccines in development. All of them teach our immune systems how to recognize and fight the virus that causes COVID-19. Sometimes this process can cause symptoms, such as fever. These symptoms are normal and are a sign that the body is building protection against the virus that causes COVID-19.

It typically takes a few weeks for the body to build immunity (protection against the virus that causes COVID-19) after vaccination. That means it’s possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and still get sick. This is because the vaccine has not had enough time to provide protection.

After getting vaccinated, you may have some side effects, which are normal signs that your body is building protection. The most common side effects are pain and swelling in the arm where you received the shot. In addition, you may have fever, chills, tiredness, and headache. These side effects may affect your ability to do daily activities, but they should go away in a few days.

Yes. If you are pregnant, you may choose to be vaccinated when it’s available to you. There is currently no evidence that antibodies formed from COVID-19 vaccination cause any problem with pregnancy, including the development of the placenta.

People who are trying to become pregnant now or who plan to try in the future may receive the COVID-19 vaccine when it becomes available to them. There is no evidence that fertility problems are a side effect of any vaccine, including COVID-19 vaccines. There is no routine recommendation for taking a pregnancy test before you get a COVID-19 vaccine.

If you have questions about getting vaccinated, talking with a healthcare provider may might help you make an informed decision.

We don’t know how long protection lasts for those who are vaccinated. What we do know is that COVID-19 has caused very serious illness and death for a lot of people. If you get COVID-19, you also risk giving it to loved ones who may get very sick. Getting a COVID-19 vaccine is a safer choice.

Experts are working to learn more about both natural immunity and vaccine-induced immunity.

• Wear a mask over your nose and mouth
• Stay at least 6 feet away from others
• Avoid crowds
• Avoid poorly ventilated spaces
• Wash your hands often

It’s important for everyone to continue using all the tools available to help stop this pandemic as we learn more about how COVID-19 vaccines work in real-world conditions. Experts are also looking at how many people get vaccinated and how the virus is spreading in communities. We also don’t yet know whether getting a COVID-19 vaccine will prevent you from spreading the virus that causes COVID-19 to other people, even if you don’t get sick yourself.

Yes, you should be vaccinated regardless of whether you already had COVID-19. That’s because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19. Even if you have already recovered from COVID-19, it is possible—although rare—that you could be infected with the virus that causes COVID-19 again.

If you were treated for COVID-19 with monoclonal antibodies or convalescent plasma, you should wait 90 days before getting a COVID-19 vaccine. Talk to your doctor if you are unsure what treatments you received or if you have more questions about getting a COVID-19 vaccine.

Experts are still learning more about how long vaccines protect against COVID-19 in real-world conditions.

The ingredients in currently available COVID-19 vaccines include mRNA, lipids, salts, sugars, and buffers. Buffers help maintain the stability of the pH solution. Vaccine ingredients can vary by manufacturer.

The federal government is providing the vaccine free of charge to all people living in the United States. Vaccination providers can be reimbursed for vaccine administration fees by the patient’s public or private insurance company or, for uninsured patients, by the Health Resources and Services Administration’s Provider Relief Fund. No one can be denied a vaccine if they are unable to pay a vaccine administration fee.

People with underlying medical conditions can receive the FDA-authorized COVID-19 vaccines as long as they have not had an immediate or severe allergic reaction to a COVID-19 vaccine or to any of the ingredients in the vaccine. Learn more about vaccination considerations for people with underlying medical conditions. Vaccination is an important consideration for adults of any age with certain underlying medical conditions because they are at increased risk for severe illness from COVID-19.

No. People with COVID-19 who have symptoms should wait to be vaccinated until they have recovered from their illness and have met the criteria for discontinuing isolation; those without symptoms should also wait until they meet the criteria before getting vaccinated. This guidance also applies to people who get COVID-19 before getting their second dose of vaccine.
