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
