Fore More information and updates on COVID-19 , please visit https://www.cdc.gov/coronavirus/2019-ncov/index.html .
What if I lost my vaccination card?
If you have lost your vaccination card or don’t have a copy, contact your vaccination provider site where you received your vaccine to access your vaccination record. Learn more about how you can locate your vaccination provider.
If I have already had COVID-19 and recovered, do I still need to get vaccinated with a COVID-19 vaccine?
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. Studies have shown that vaccination provides a strong boost in protection in people who have recovered from COVID-19. 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.
If you or your child has a history of multisystem inflammatory syndrome in adults or children (MIS-A or MIS-C), consider delaying vaccination until you or your child have recovered from being sick and for 90 days after the date of diagnosis of MIS-A or MIS-C. Learn more about the clinical considerations people with a history of multisystem MIS-C or MIS-A.
Experts are still learning more about how long vaccines protect against COVID-19. CDC will keep the public informed as new evidence becomes available.
Is it safe for my child to get a COVID-19 vaccine?
Yes. Studies show that COVID-19 vaccines are safe and effective. Like adults, children may have some side effects after COVID-19 vaccination. These side effects may affect their ability to do daily activities, but they should go away in a few days. Children 12 years and older are now eligible to get vaccinated against COVID-19. COVID-19 vaccines have been used under the most intensive safety monitoring in U.S. history, including studies in children 12 years and older. Your child cannot get COVID-19 from any COVID-19 vaccine.
Why should my child get vaccinated against COVID-19?
COVID-19 vaccination can help protect your child from getting COVID-19. Although fewer children have been sick with COVID-19 compared to adults, children can be infected with the virus that causes COVID-19, can get sick from COVID-19, and can spread the virus that causes COVID-19 to others. Getting your child vaccinated helps to protect your child and your family. Vaccination is now recommended for everyone 12 years and older. Currently, the Pfizer-BioNTech COVID-19 Vaccine is the only one available to children 12 years and older.
What are the ingredients in COVID-19 Vaccines?
Vaccine ingredients can vary by manufacturer. To learn more about the ingredients in authorized COVID-19 vaccines, see...

Do I need to wear a mask and avoid close contact with others if I am fully vaccinated?
After you are fully vaccinated for COVID-19 you can resume many activities without wearing a mask or staying 6 feet apart, except:
if you are indoors in public and you are in an area of substantial or high transmission.
or where required by federal, state, local, tribal, or territorial laws, rules, and regulations, including local business and workplace guidance.
Can I choose which COVID-19 vaccine I get?
Yes. All currently authorized and recommended COVID-19 vaccines are safe and effective, and CDC does not recommend one vaccine over another. The most important decision is to get a COVID-19 vaccination as soon as possible. Widespread vaccination is a critical tool to help stop the pandemic.
People should be aware that a risk of a rare condition called thrombosis with thrombocytopenia syndrome (TTS) has been reported following vaccination with the J&J/Janssen COVID-19 Vaccine. TTS is a serious condition that involves blood clots with low platelet counts. This problem is rare, and most reports were in women between 18 and 49 years old. For women 50 years and older and men of any age, this problem is even more rare. There are other COVID-19 vaccine options available for which this risk has not been seen (Pfizer-BioNTech, Moderna).

If I am pregnant, can I get the COVID-19 vaccine?
Yes, COVID-19 vaccination is recommended for all people 12 years and older, including people who are pregnant, breastfeeding, trying to get pregnant now, or might become pregnant in the future. You might want to have a conversation with your healthcare provider about COVID-19 vaccination. While such a conversation might be helpful, it is not required before vaccination. Learn more about vaccination considerations for people who are pregnant or breastfeeding.
If you are pregnant and have received a COVID-19 vaccine, we encourage you to enroll in v-safe, CDC’s smartphone-based tool that provides personalized health check-ins after vaccination. A v-safe pregnancy registry has been established to gather information on the health of pregnant people who have received a COVID-19 vaccine.
How long does protection from a COVID-19 vaccine last?
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. CDC will keep the public informed as new evidence becomes available.
How many doses of COVID-19 Vaccine will I need to get?
The number of doses needed depends on which vaccine you receive. To get the most protection:
Two Pfizer-BioNTech vaccine doses should be given 3 weeks (21 days) apart.
Two Moderna vaccine doses should be given 1 month (28 days) apart.
Johnson & Johnsons Jansen (J&J/Janssen) COVID-19 vaccine requires only one dose.
If you receive a vaccine that requires two doses, you should get your second shot as close to the recommended interval as possible. However, your second dose may be given up to 6 weeks (42 days) after the first dose, if necessary.. You should not get the second dose earlier than the recommended interval.
If I have an underlying condition, can I get a COVID-19 vaccine?
People with underlying medical conditions can receive a COVID-19 vaccine 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.
Can I get vaccinated against COVID-19 while I am currently sick with 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.
