These include mental health impairments such as depression and anxiety, as well as more severe forms such as psychotic disorders. While microvascular alterations and persistent inflammation due to SARS-CoV-2 infection are some of the potential physiological mechanisms linked to mental health illnesses after COVID-19, psychosocial causes such as anxiety about the disease and the outcomes post-COVID-19 have also been implicated. Furthermore, although the rapid development of COVID-19 vaccines was instrumental in limiting the transmission and morbidity of SARS-CoV-2 infections, the long-term implications of these rapidly developed vaccines on o.
