Because the COVID-19 pandemic has been raging for almost 2 years now, most people have heard of the different viral variants that threaten the effectiveness of full protection with vaccines. This topic can be confusing to anyone who is not familiar with viruses or virology. This article will: 1) help you understand what viral variants are, and 2) explain where they come from. Viruses rely on host organisms (e.g., people and/or animals) to make more copies of themselves so that they can infect more hosts. However, hosts typically mount an immune response to clear a virus, which creates a challenge for viruses to overcome…

Or, you might be like me, and this invasion has sparked a curiosity of wanting to learn more about cicadas…
A quick summary of the immune system and the COVID-19 vaccine

Vaccines are designed to pose a foreign invader, such as a virus or bacterium, to your adaptive immune system without causing you to be sick. Our immune systems are quite amazing, which also makes them quite complex. Here, we will focus only on a few aspects that are important for understanding vaccine development…

Obviously, we have all heard about COVID–19, the novel coronavirus outbreak that originated at a seafood market in Wuhan China. There is a LOT of information out there about COVID–19 but there are also still many open questions that we are desperately looking for answers to. I wanted to tackle this topic from a scientific approach, so what exactly is COVID–19? The Coronavirus family is characterized as an enveloped positive strand RNA virus, much like the SARS-coronavirus that infected people in 2003, but with a slightly different genome. What does that mean? Let’s break it down…
