Why Only Some Vaccines Need Booster Shots
Vaccines teach your immune system to recognize pathogens, but sometimes your body needs a bit of a reminder.

COVID Variant Recombination: Threat or Achilles Heel?
Scientists may have found a recombinant variant of COVID-19 in the wild, and its mixed DNA could be essential to the coronavirus life cycle.

Will COVID-19 Go Away in the Summer?
COVID-19 has the potential to ebb and flow with the seasons, but because it's a novel pandemic, that doesn't mean we're off the hook this summer.

What Do We Know About T Cells and COVID-19 Immunity? | SciShow News
There's another theory about the Covid-19 pandemic going around, and while it is pretty cool, it's not exactly the solution some are suggesting it might be.

How to Make a COVID-19 Vaccine
One year to eighteen months might seem like a while to wait for a COVID-19 vaccine, but there's a good reason finding and approving a candidate takes a whole lot of time.

Top 5 Deadliest Diseases
Hank scares our pants off with a tale of the five deadliest infectious diseases in the world.
Professor Dave Explains
Introduction to Adaptive Immunity
After a rigorous examination of all the components of the innate system, it's finally time to pivot over to the adaptive immune system. If you thought innate immunity was impressive, get ready to be amazed! Adaptive immunity is one of...
Professor Dave Explains
Innate Lymphoid Cells
Wrapping up the innate immune system we have one more cell type to examine, and that is innate lymphoid cells. These are a family of lymphocytes that are considered to be the innate counterparts of T cells from the adaptive immunity,...
Professor Dave Explains
Natural Killer Cells: The Tumor Killers
Just a little bit left to go with the innate immune cells, so let's look at natural killer cells! These are cells which show cytolytic activity towards physiologically stressed cells like tumor cells and virus-infected cells. Let's break...
Professor Dave Explains
Basophils and Eosinophils
We are almost done looking at the cells of the innate immune system, but two of the most important are basophils and eosinophils. What do these cells do? What types of receptors do they express? Let's get a closer look!
Professor Dave Explains
Mast Cells: Strategic Granulocytes
We've covered macrophages, dendritic cells, and neutrophils, so let's move on the mast cells. These are examples of granulocytes, and they are involved in a variety of immune responses. Let's get a closer look now!
Professor Dave Explains
Neutrophils: First Line of Defense
We've covered macrophages and dendritic cells, so let's move on to neutrophils. These are the most abundant white blood cells, and they act as the first line of defense in innate immunity. How do they form, and what do they do...
Professor Dave Explains
Dendritic Cells: The Regulators
With macrophages covered, let's move on to another innate immune cell type, dendritic cells. These are able to capture and present antigens to the T cells of the adaptive immune system, prompting a variety of outcomes. Let's take a look...
Professor Dave Explains
Macrophages: The Destroyers
Before we move on from the innate immune system, let's go through all the cell types one by one, so that we can better understand them. Let's start with macrophages, which are long-lived phagocytic cells. They play a pivotal role in...
Professor Dave Explains
Types of Immune Cell Receptors
We've talked a bit about how immune cell receptors operate, but now it's time to get specific about the types of receptors that immune cells can express. That means we need to discuss antigen receptors, costimulatory receptors,...
Professor Dave Explains
Cytokines and Chemokines
We've talked about how immune cells communicate with one another using cytokines and chemokines, but we have not yet gone into detail regarding these soluble protein signals. What are the names of these molecules, which include...
