Mumps IgG titers, levels of IgG antibody, have been correlated to lowered severity in recovered COVID-19 patients who had the Merck MMR II vaccine, and that has led a group to speculate that the MMR…

A new study found that natural selection, a key mechanism in biological evolution, favors pathogens with more virulence - how much harm they cause - at the point the disease emerges in a new host…

To estimate infection rates of viruses like SARS-CoV-2, immunologists use a basic reproduction number, known as R0 (pronounced “R naught”) - an expression of the number of people likely to catch a…
