Of note, more people experienced these side effects after the second dose than after the first dose, so it is important for vaccination providers and recipients to expect that there may be some side effects after either dose, but even more so after the second dose.

How do I transfer my proof of vaccination from another country to get a proof of vaccination card in the United States?

See full answer

CDC does not keep vaccination records or determine how vaccination records are used. To update your records with vaccines you received while outside of the United States, you may:

  • Contact the immunization information system (IIS) in your state. You can find state IIS information on the CDC website.
  • Contact your healthcare provider or your local or state immunization program through your state’s health department.

The CDC-labeled white COVID-19 Vaccination Record Cards are only issued to people vaccinated in the United States. CDC recommends you keep your documentation of being vaccinated in the other country as proof of vaccination. CDC also recommends checking with your primary care provider or state health department for options to document your vaccination status domestically.

Can you mix COVID-19 vaccines?

Can I mix the COVID-19 booster shots?

How long is the Pfizer vaccine for COVID-19 effective?

How many doses of COVID-19 vaccine will I need to get?

See full answer

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.

What is the COVID-19 antibody test?

An antibody test looks for antibodies that are made by the immune system in response to a threat, such as a specific virus. Antibodies can help fight infections. Antibodies can take several days or weeks to develop after you have an infection and may stay in your blood for several weeks after recovery. Because of this, antibody tests should not be used to diagnose an active coronavirus infection. At this time, researchers do not know if the presence of antibodies means that you are immune to the coronavirus in the future.

What does a positive COVID-19 antibody test result mean?

A positive test result with the SARS-CoV-2 antibody test indicates that antibodies to SARS-CoV-2 were detected, and the individual has potentially been exposed to COVID-19.

Can you have COVID-19 and still test negative for antibody test?

A negative test means that you have no COVID-19 antibodies, so you probably were not infected with the COVID-19 virus in the past. Because it takes time for antibodies to develop, false-negative test results can happen if the blood sample is collected too soon after your infection started.

What is the false negative rate from COVID-19 antibody test results?

The reported rate of false negatives is 20%. However, the range of false negatives is from 0% to 30% depending on the study and when in the course of infection the test is performed.

What does a negative COVID-19 antigen test result mean in asymptomatic persons?

Negative test results using a viral test (NAAT or antigen) in asymptomatic persons with recent known or suspected exposure suggest no current evidence of infection. These results represent a snapshot of the time around specimen collection and could change if tested again in one or more days.
