See full answer•The FDA provided an update on one potential treatment called convalescent plasma and is encouraging those who have recovered from COVID-19 to donate plasma to help others fight this disease. Convalescent plasma is an antibody-rich product made from blood donated by people who have recovered f from the disease caused by the virus. The agency launched a new webpage to guide recovered COVID-19 patients to local blood or plasma collection centers to discuss their eligibility and potentially schedule an appointment to donate. The webpage also includes information for those interested in participating in the expanded access protocol, conducting clinical trials, or submitting single patient emergency investigational new drug applications.Apr 16, 2020
A positive test means you have COVID-19 antibodies in your blood, which indicates past infection with the virus. It's possible to have a positive test result even if you never had any symptoms of COVID-19. False-positive test results can occur.May 6, 2021
If you were treated for COVID-19 symptoms with monoclonal antibodies or convalescent plasma, you should wait 90 days before getting a COVID-19 vaccine.
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.Jan 7, 2022

SARS-CoV-2 antibody or serology tests look for antibodies in a blood sample to determine if an individual has had a past infection with the virus that causes COVID-19. These types of tests cannot be used to diagnose a current infection.May 19, 2021
Yes, the COVID-19 vaccines are recommended, even if you had COVID-19.Nov 23, 2021
It is not recommended you take over-the-counter medicine – such as ibuprofen, aspirin, or acetaminophen – before vaccination for the purpose of trying to prevent vaccine-related side effects. It is not known how these medications might affect how well the vaccine works.
Yes, you should be vaccinated regardless of whether you already had COVID-19.
See full answer• You may not have COVID-19 antibodies. This could be because you have not had an infection with the virus that causes COVID-19 or have not received a COVID-19 vaccine. - Antibody testing is not currently recommended to determine if you are immune to COVID-19 following COVID-19 vaccination.• Some antibody tests will only detect antibodies from infection, not from vaccination with the virus that causes COVID-19.• You could have a current infection, been recently infected, or been recently vaccinated. It typically takes 1 to 3 weeks after infection or vaccination for your body to make antibodies. If you are infected, you may get sick and spread the virus before you develop antibodies.
Antibody tests can play an important role in identifying individuals who may have been exposed to the SARS-CoV-2 virus and may have developed an adaptive immune response. However, antibody tests should not be used at this time to determine immunity or protection against COVID-19 at any time, and especially after a person has received a COVID-19 vaccination.May 19, 2021
At this time, it is unknown for how long antibodies persist following infection and if the presence of antibodies confers protective immunity.Jan 31, 2022
