Why do antibodies fade after a COVID-19 infection, and will the same thing happen with vaccines?

Why do antibodies fade after a COVID-19 infection, and will the same thing happen with vaccines?

THE goal of the COVID-19 vaccines being rolled out worldwide is to stimulate our immune systems into creating a protective response against the coronavirus, particularly by generating antibodies. These antibodies then circulate in our blood until needed in the future, attacking and removing the coronavirus quickly from our bodies if we become infected. STEVEN SMITH, Senior Lecturer in Biomedical Sciences, Brunel University London The speed with which the scientific and medical communities have developed and tested these new vaccines has been extraordinary. However, this short timescale leaves us with some outstanding questions. Key among these is how long the protection…

COVID-19 causes some patients’ immune systems to attack their own bodies, which may contribute to severe illness

MATTHEW WOODRUFF, Instructor, Lowance Center for Human Immunology, Emory University ACROSS the world, immunologists who retooled their labs to join the fight against SARS-CoV-2 are furiously trying to explain why some people get so sick while others recover unscathed. The pace is dizzying, but some clear trends have emerged. One area of focus has been the production of antibodies – powerful proteins capable of disabling and killing invading pathogens like viruses. Of great concern has been the sporadic identification of so-called autoreactive antibodies that, instead of targeting disease causing microbes, target the tissues of individuals suffering from severe cases of…
