What is a monoclonal antibody for COVID-19?

Monoclonal antibodies are laboratory-produced molecules that act as substitute antibodies that can restore, enhance or mimic the immune system's attack on cells. Monoclonal antibodies for COVID-19 may block the virus that causes COVID-19 from attaching to human cells, making it more difficult for the virus to reproduce and cause harm. Monoclonal antibodies may also neutralize a virus.6 days ago

What is the difference between monoclonal antibodies and the COVID-19 vaccine?

See full answer

There is currently no FDA-approved post-exposure prophylaxis for people who may have been exposed to COVID-19. For information about registered clinical trials of investigational therapeutics for pre or post exposure prophylaxis of SARS-CoV-2 infection, visit ClinicalTrials.gov.

For more information on movement restrictions, monitoring for symptoms, and evaluation after possible exposure to COVID-19, see Interim US Guidance for Risk Assessment and Public Health Management of Persons with Potential Coronavirus Disease 2019 (COVID-19) Exposure in Travel-associated or Community Settings and Interim U.S Guidance for Risk Assessment and Public Health Management of Healthcare Personnel with Potential Exposure in a Healthcare Setting to Patients with Coronavirus Disease 2019 (COVID-19).
