The Moderna vaccine against COVID-19 gJanuary antibodies that lasted 90 days after vaccination“Good news because approval is being studied in various countries,” says a study conducted on 34 participants since the start of clinical trials and published Thursday in the New England Journal of Medicine.

The length of the defense is undoubtedly longerBut this is the first data in a several-month period independently validated by a scientific journal. Participants are followed for 13 months to check longer-term protection, the authors say.

Researchers from the National Institutes of Health evaluated the level of two types of antibodies against them Coronavirus 90 days after the second dose of the vaccine, given in turn 28 days after the first.

They observed a “small” and expected decrease in the level of antibodies in vaccinated participants, but to a degree that remained high and above the natural immunity revealed in COVID-19 infected and recovering patients.

Also, no serious side effects were observed in the so-called phase 1 trial, which began in March. Antibodies are just one component of the immune response, along with B lymphocytes (immune memory, antibody production) and T (which kills infected cells).

The researchers note that the data on immune memory cells is not yet known.

Anthony Fauci, director of the Institute of Infectious Diseases, recently told AFP that he was “sure” that the immune memory created by the vaccine would last for some time.
