When should you take monoclonal?
Monoclonal antibodies, or mAbs, are made in a laboratory to fight a particular infection (in this case, SARS-CoV-2) and are given to you directly in an infusion.

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.Mar 31, 2022

What is the difference between monoclonal antibodies and the COVID-19 vaccine?
COVID-19 vaccines help stimulate and prepare a person's immune system to respond if they are exposed to the virus. However, monoclonal antibodies boost the immune system only after a person is already sick, speeding up their immune response to prevent COVID-19 from getting worse.Nov 8, 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.
Who could benefit from monoclonal antibody therapy to prevent COVID-19?
See full answerVaccines are the best way to protect against COVID-19. But some people with weakened immune systems do not produce enough antibodies after vaccination, and others are severely allergic to the vaccine. The FDA recently authorized Evusheld, a pre-exposure prophylaxis (PrEP) monoclonal antibody therapy developed by AstraZeneca, which should help prevent COVID-19 in these populations.To be eligible for Evusheld, individuals must be 12 years or older and have a moderately to severely weakened immune system, or have a history of severe adverse reactions to the COVID-19 vaccine or its components. In addition, the therapy cannot be given to someone with a current SARS-CoV-2 infection, or who has been recently exposed to someone who is infected. Evusheld is given as two consecutive shots, and evidence suggests it can help prevent symptomatic infection for at least six months.Apr 1, 2022

What antibody targets the RBD of the S protein?
Bamlanivimab (also known as LY-CoV555 and LY3819253) is a neutralizing monoclonal antibody that targets the RBD of the S protein of SARS-CoV-2. Etesevimab (also known as LY-CoV016 and LY3832479) is another neutralizing monoclonal antibody that binds to a different but overlapping epitope in the RBD of the SARS-CoV-2 S protein. Casirivimab (previously REGN10933) and imdevimab (previously REGN10987) are recombinant human monoclonal antibodies that bind to nonoverlapping epitopes of the S protein RBD of SARS-CoV-2.
