Rapid dynamic changes of FL.2 variant: a case report of COVID-19 breakthrough infection.
Immune responses within the context of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vary. Typically the virus is cleared within 2 weeks of infection but immunocompromised individuals can have prolonged infections[1, 2]. Weak immune systems increase infection risk and post-COVID-19 clinical sequelae, even post-vaccination[3]. Prolonged infections may facilitate viral evolution, including the evolution of immune-evasive viral variants. SARS-CoV-2 variants of concern (VOCs) such as Alpha, Beta and Gamma may have originated within the context of long-term infections in immunocompromised individuals[4-6].
