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 are monoclonal antibodies?
Monoclonal antibodies to fight COVID-19 are artificially manufactured antibodies designed to mimic your body’s natural antibodies.
Who is eligible for monoclonal antibodies?
Monoclonal antibody treatments are only available to certain patients.
How monoclonal antibodies are administered

Why are antibodies made?
Antibodies are naturally made in our bodies to fight infection. Without antibodies, a virus can enter and infect a cell. With antibodies, however, when the virus tries to enter the cell, antibodies block the virus. Monoclonal antibodies (mAbs) are antibodies developed in a laboratory to help our bodies fight infection.
