Trained Innate Immunity, Epigenetics, and Covid-19

Authors: Alberto Mantovani, M.D., and Mihai G. Netea, M.D. Innate immunity is mediated by different cell types and cell-associated or fluid-phase pattern-recognition molecules and plays a key role in tissue repair and resistance against pathogens.1 Exposure to selected vaccines, such as bacille Calmette–Guérin (BCG) or microbial components, can increase the baseline tone of innate immunity and trigger […]

Good news: Mild COVID-19 induces lasting antibody protection

People who have had mild illness develop antibody–producing cells that can last lifetime Authors: by Tamara Bhandari•May 24, 2021 Months after recovering from mild cases of COVID-19, people still have immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine […]

Pros and Cons of Adenovirus-Based SARS-CoV-2 Vaccines

Authors: Eric J. Kremer1,∗ Main Text Most of us might be surprised by the rudimentary scientific rationale prevalent in the field of vaccine research just 50 years ago. For over a century after Louis Pasteur’s vaccine against rabies, approaches usually consisted of inactivating a virus, injecting it, and seeing if it protected the host. Unlike […]
