Billions of dollars are being invested in the development of vaccines against the coronavirus. Until one arrives, many scientists have turned to tried-and-true vaccines to see whether they may confer broad protection, and may reduce the risk of coronavirus infection, as well.
Old standbys like the Bacille Calmette-Guerin tuberculosis vaccine and the polio vaccine appear to help train the immune system to respond to a broad variety of infections, including from bacteria, viruses and parasites, experts say.
As an epidemiologist or “disease detective,” a question I am frequently asked regarding SARS-CoV-2 (the virus that causes COVID-19 disease) is: “How does someone become infected?”
Costa Rica is set to begin clinical trials on antibody-rich plasma that has been extracted from horses with the purpose of treating COVID-19 patients.
Two versions of the plasma were shown to inhibit the infectivity of SARS-CoV-2, the virus that causes COVID-19, in tests performed at the National Center for Biodefense and Infectious Diseases in the United States.
In a laboratory in New York City, researchers coaxed a key piece of the coronavirus — its infamous outer “spike” — to mutate so that it became invisible to disease-fighting antibodies, according to a new study that has not yet been published in a scientific journal.
