«Based on our results and previous data from our line of research, ‘MBL lo’ emerges as a new independent risk marker for more severe covid. Subjects with ‘MBL lo’ have impaired immunity and would therefore be more prone to severe infections and potentially also develop inadequate responses to vaccination,» the researchers said.

The study has detected the presence of ‘MBL lo’ in the 29% of covid patientsa frequency that doubles that observed in the general population, while the prevalence of ‘MBL lo’ was even higher in patients admitted to hospital (by 40 percent), including critically ill patients.
