Risk Of Reinfection From Sars Cov 2 An Update Of An Antibody Response Following Sars Cov 2 Infection And Implications For Immunity

The strength and expected duration of immunity, both from infection and from vaccination, are important for public health planning and clinical practice. Understanding the nature and duration of immunity acquired by previous infection to SARS-CoV-2 is a critical component of modeling the course of the pandemic and formulating public health policy. Better data on the risk for reinfection and on the relationship of antibody status to protection from reinfection can help guide practice policies regarding antibody testing and vaccination timing, particularly in immunocompromised patients and those with other comorbidities who have a higher risk of worse outcomes with COVID-19.
