COVID-19 vaccine generates immune structures critical for lasting immunity

The first two COVID-19 vaccines authorized for emergency use by the Food and Drug Administration (FDA) employed a technology that had never before been used in FDA-approved vaccines. Both vaccines performed well in clinical trials, and both have been widely credited with reducing disease, but concerns remain over how long immunity induced by the new vaccine technology will last. Now, […]

What is Gain-of-Function Research?

Gain-of-function research refers to the serial passaging of microorganisms to increase their transmissibility, virulence, immunogenicity, and host tropism by applying selective pressure to a culture. Image Credit: vchal/Shutterstock.com This is performed in a research context to understand the way in which a pathogen adapts to environmental pressures, allowing disease control measures to be better planned, and potential vaccines and therapies […]
