Frequently Asked Questions about COVID-19 Vaccination
Benefits of Getting a COVID-19 Vaccine We understand that some people may be concerned about getting vaccinated now that COVID-19 vaccines are available in the United States. While more COVID-19 vaccines are being developed as quickly as possible, routine processes and procedures remain in place to ensure the safety of any vaccine that is authorized or approved for use. Safety is a top priority, and there are many reasons to get vaccinated.
Can a COVID-19 vaccine make me sick with COVID-19? No. None of the COVID-19 vaccines contain the live virus that causes COVID-19 so a COVID-19 vaccine cannot make you sick with COVID-19. Facts about COVID-19 Vaccines
Below is a summary of the benefits of COVID-19 vaccination based on what we currently know. CDC will continue to update this page as more data become available.
COVID-19 vaccination will help keep you from getting COVID-19 All COVID-19 vaccines currently available in the United States have been shown to be highly effective at preventing COVID-19. Learn more about the different COVID-19 vaccines. All COVID-19 vaccines that are in development are being carefully evaluated in clinical trials and will be authorized or approved only if they make it substantially less likely you’ll get COVID-19. Learn more about how federal partners are ensuring COVID-19 vaccines work. Based on what we know about vaccines for other diseases and early data from clinical trials, experts believe that getting a COVID-19 vaccine may also help keep you from getting seriously ill even if you do get COVID-19. Getting vaccinated yourself may also protect people around you, particularly people at increased risk for severe illness from COVID-19. Experts continue to conduct more studies about the effect of COVID-19 vaccination on severity of illness from COVID-19, as well as its ability to keep people from spreading the virus that causes COVID-19. COVID-19 vaccination is a safer way to help build protection COVID-19 can have serious, life-threatening complications, and there is no way to know how COVID-19 will affect you. And if you get sick, you could spread the disease to friends, family, and others around you. Clinical trials of all vaccines must first show they are safe and effective before any vaccine can be authorized or approved for use, including COVID-19 vaccines. The known and potential benefits of a COVID-19 vaccine must outweigh the known and potential risks of the vaccine for use under what is known as an Emergency Use Authorization (EUA). Watch a video on what an EUA is. Getting COVID-19 may offer some natural protection, known as immunity. Current evidence suggests that reinfection with the virus that causes COVID-19 is uncommon in the 90 days after initial infection. However, experts don’t know for sure how long this protection lasts, and the risk of severe illness and death from COVID-19 far outweighs any benefits of natural immunity. COVID-19 vaccination will help protect you by creating an antibody (immune system) response without having to experience sickness. Both natural immunity and immunity produced by a vaccine are important parts of COVID-19 disease that experts are trying to learn more about, and CDC will keep the public informed as new evidence becomes available. COVID-19 vaccination will be an important tool to help stop the pandemic Wearing masks and social distancing help reduce your chance of being exposed to the virus or spreading it to others, but these measures are not enough. Vaccines will work with your immune system so it will be ready to fight the virus if you are exposed. The combination of getting vaccinated and following CDC’s recommendations to protect yourself and others will offer the best protection from COVID-19. Stopping a pandemic requires using all the tools we have available. As experts learn more about how COVID-19 vaccination may help reduce spread of the disease in communities, CDC will continue to update the recommendations to protect communities using the latest science.

Ensuring the Safety of COVID-19 Vaccines in the United States
Content provided and maintained by the US Centers for Disease Control and Prevention (CDC). Please see our system usage guidelines and disclaimer.
Now that there are authorized and recommended COVID-19 vaccines in the United States, accurate vaccine information is critical.
How do I know which sources of COVID-19 vaccine information are accurate?
It can be difficult to know which sources of information you can trust. Learn more about finding credible vaccine information.
Can a COVID-19 vaccine make me sick with COVID-19? illustration of person coughing without covering their mouth 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. Learn more about how COVID-19 vaccines work.
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 a COVID-19 vaccine, will I test positive for COVID-19 on a viral test? illustration of positive COVID-19 test results No. Neither the recently authorized and recommended vaccines nor the other COVID-19 vaccines currently in clinical trials in the United States can cause you to test positive on viral tests, which are used to see if you have a current infection.
If your body develops an immune response—the goal of vaccination—there is a possibility you may test positive on some antibody tests. Antibody tests indicate you had a previous infection and that you may have some level of protection against the virus. Experts are currently looking at how COVID-19 vaccination may affect antibody testing results.
If I have already had COVID-19 and recovered, do I still need to get vaccinated with a COVID-19 vaccine? illustration of a COVID-19 vaccine vial 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. Learn more about why getting vaccinated is a safer way to build protection than getting infected.
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. CDC will keep the public informed as new evidence becomes available.
Will a COVID-19 vaccination protect me from getting sick with COVID-19? illustration of a person Yes. COVID-19 vaccination works by teaching your immune system how to recognize and fight the virus that causes COVID-19, and this protects you from getting sick with COVID-19.
Being protected from getting sick is important because even though many people with COVID-19 have only a mild illness, others may get a severe illness, have long-term health effects, or even die. There is no way to know how COVID-19 will affect you, even if you don’t have an increased risk of developing severe complications. Learn more about how COVID-19 vaccines work.
Will a COVID-19 vaccine alter my DNA? illustration of DNA strand No. COVID-19 vaccines do not change or interact with your DNA in any way.
There are currently two types of COVID-19 vaccines that have been authorized for use in the United States: messenger RNA (mRNA) vaccines and viral vector vaccines.
The Pfizer-BioNTech and Moderna vaccines are mRNA vaccines, which teach our cells how to make a protein that triggers an immune response. The mRNA from a COVID-19 vaccine never enters the nucleus of the cell, which is where our DNA is kept. This means the mRNA cannot affect or interact with our DNA in any way. Instead, COVID-19 mRNA vaccines work with the body’s natural defenses to safely develop immunity to disease. Learn more about how COVID-19 mRNA vaccines work.
Johnson & Johnson’s Janssen COVID-19 vaccine is a viral vector vaccine. Viral vector vaccines use a modified version of a different, harmless virus (the vector) to deliver important instructions to our cells to start building protection. The instructions are delivered in the form of genetic material. This material does not integrate into a person’s DNA. These instructions tell the cell to produce a harmless piece of virus that causes COVID-19. This is a spike protein and is only found on the surface of the virus that causes COVID-19. This triggers our immune system to recognize the virus that causes COVID-19 and to begin producing antibodies and activating other immune cells to fight off what it thinks is an infection. Learn more about how viral vector vaccines work.
At the end of the process, our bodies have learned how to protect against future infection from COVID-19. That immune response and the antibodies that our bodies make protect us from getting infected if the real virus enters our bodies.
Is it safe for me to get a COVID-19 vaccine if I would like to have a baby one day? illustration of person thinking about having a baby Yes. If you are trying to become pregnant now or want to get pregnant in the future, you may receive a COVID-19 vaccine when one is available to you.
There is currently no evidence that COVID-19 vaccination causes any problems with pregnancy, including the development of the placenta. In addition, there is no evidence that fertility problems are a side effect of any vaccine, including COVID-19 vaccines.
Like all vaccines, scientists are studying COVID-19 vaccines carefully for side effects now and will continue to study them for many years.

Who Gets Vaccinated When?
President Biden called for vaccines to be available for anyone 18 years and older who need one.
The recommendations were made with these goals in mind:
Decrease death and serious disease as much as possible. Preserve functioning of society. Reduce the extra burden COVID-19 is having on people already facing disparities.
