The new study reveals how long antibodies last after the Coronacterius

This is true “despite the severity of the disease, the age of the patient, or the presence of other pathology”, according to a study conducted by the prestigious “hospital. San Rafaele” in Milan in collaboration with the Public Health Institute.

“The presence of antibodies, although reduced over time, is long-term: eight months after diagnosis, only three patients” from 162 (from which 29 died) were no longer positive for the test of antibodies”, the study specified.

In addition, the early beginning of antibodies is said to be <x0Healbious to fight infection successfully: those who fail to produce them in the first two weeks after the infection have a higher risk of severe development of COVID-19”.

By means of techniques already used to study anti - vaccines HIV, researchers have developed a new method of measuring antibodies that neutralise SARS-CoV-2.

The study was conducted in 162 positive patients (67 per cent men aged 63 years), who came to emergency service in “San Rafaelo” during the first wave of pandemic in Italy.

The first blood samples were collected at the time of diagnosis in March-April 2020, and the last at the end of November 2020.

Of these patients, 57 percent had other pathology, mainly hypertension (44 percent) and diabetes (24 percent).
