Risk and Protective Factors for COVID-19 Morbidity, Severity, and Mortality

Jin-jin Zhang et al.

Summary: The outbreak of COVID-19 has become a global health crisis, with various factors such as age, sex, comorbidities, and racial/ethnic disparities influencing its morbidity. Children tend to experience milder illnesses, and factors like a healthy diet, sufficient nutrition, vaccination, and atopic conditions may act as protective factors. The effects of current therapies for COVID-19 and the bidirectional relationship between asthma and COVID-19 are still unclear.

Summary: Research has found that certain monoclonal antibodies approved for human therapeutic use have the potential to cause antibody-dependent enhancement (ADE) of SARS-CoV-2 infection at specific antibody concentrations. Additionally, some sera collected from individuals vaccinated with mRNA vaccines exhibited ADE activity, and ADE effects were observed in the case of Omicron infection. These findings suggest the possibility of adverse effects caused by these antibodies in addition to their therapeutic or preventive effects.
