Dutch woman dies after catching Covid-19 twice, the first reported reinfection death

An elderly Dutch woman has become the first known person to die from catching Covid-19 twice, according to experts, raising serious questions about how long immunity and antibodies can last. The woman, 89, suffered from a rare type of bone marrow cancer called Waldenström's macroglobulinemia. Her immune system was compromised due to the cell-depleting therapy she received, the researchers at Maastricht University Medical Center in the Netherlands wrote in a paper accepted for publication in the journal Clinical Infectious Diseases. However, the researchers said her natural immune response could still have been 'sufficient' to fight-off Covid-19, as the type of treatment she received for cancer 'does not necessarily result in life threatening disease.'
