Vaccination, Explained!
Exploring the answers to common questions
How do vaccines work? Why does getting a vaccine sometimes make you feel sick? What are antibodies, and how does your body make them?
It’s normal to have questions about the complex science of vaccination, viruses and immunity. That’s why our researchers have set out to answer some of the questions we hear most often from our Science Centre visitors.
In this series of videos, we’ll explore what happens in your body when you get a vaccine, how viral mutation works, and the power of antibodies.
Have you ever felt pain, fever or fatigue after getting a vaccine? You’re not alone! Find out what’s happening inside your body as your immune system learns how to protect you from a virus.
Have you ever wondered why you need more than one dose of some vaccines? One reason is viral mutation. Learn how some viruses mutate faster than others, and find out how another dose can help keep you—and everyone else—healthier.
How do vaccines help prepare your immune system for encountering a virus? Let’s talk antibodies! Explore how antibodies come into play and learn how vaccination gives your immune system a head start.

| B3.4 | explain the primary functions of a variety of systems in animals (e.g., the circulatory system transports materials through the organism; the respiratory system supplies oxygen to and removes carbon dioxide from the body) |
| B3.5 | explain the interaction of different systems within an organism (e.g., the respiratory system brings oxygen into the body, and the circulatory system transports the oxygen to cells) and why such interactions are necessary for the organism’s survival |
| B3.4 | explain the general function of some of the systems in the human body (e.g., the function of the circulatory system is to transport materials through the body; the function of the digestive system is to absorb nutrients; the function of the respiratory system is to bring oxygen into and remove carbon dioxide from the body) |
