If a new dragon comes along, the knight will not know how to kill the dragon. It will then take longer for the knight to kill the dragon. Sometimes, it may even be too late. Before the knight learns, the dragon may destroy the castle. Similarly, if our body was not vaccinated, our body will not know how to fight the germs because it did not have the practice. By the time our body learns how to fight it, it may be too late.
When all of the knights gather at the roundtable they predict which dragons will be a threat to the castle for that year. Accordingly, they bring out weapons from their secret stash and give them to certain knights. This year, they decided that the rainbow scaled dragons may choose to attack the castle. The leader knight brings the rainbow magical dragon scale and gives it to a knight. He then sends him off to defeat the dragon. This happens with many more potential dragons. A knight will not be able to go to battle if they do not have some form of weapon.
At the round table, the knights discuss the importance of defeating each type of dragon. They think it is more important to prepare the knights to attack the stronger dragons who do more damage to the castle than the weaker dragons who cannot destroy the castle. This is why they first appoint knights to fight the stronger dragons and equip them with their necessary weapons.
In the faraway land of Vale of Gloucetershire, there are many little castles. Each kingdom has its own castle. However, in the land of Vale of Gloucetershire, the kingdoms are very close together. So, the dragons attacking a castle can attack neighbouring ones as well.
Louise turned to Sir Edward with a look of concern. “What would happen to a kingdom with no knights?” “Well,” Sir Edward responded, “Some dragons can fly so swiftly and are very dangerous, but if we can protect our own kingdom, then our neighbours are less likely to encounter dragons because we have defeated them first. If we don’t defeat the dragons quickly, the dragons can spread beyond our walls and attack the kingdoms around us. This is especially dangerous for kingdoms that have trouble fighting dragons, and it is important that we learn to fight in order to protect ourselves and our neighbouring castles. This allows the entire kingdom to be safe from the dragons too!” Louise the Brave looked out at the land. She saw some dragons that travel very fast, and others that multiplied quickly. "It would take a lot of knights to be prepared in order to prevent those dragons from spreading all across the land,” she thought. Likewise, scientists characterize germs by how quickly they can spread. Once one person gets sick, they can infect others before they manage to get better, even if they don’t look or feel sick. This is a big factor in deciding which illnesses are important to create vaccines against and how many people need to get vaccinated to protect the population and the people who cannot get vaccinated, like the young, old, or those who are already sick.
The castles remained safe and sound thanks to the brave and strong knights. Since they prepared themselves with the appropriate weapons and strategies before the battle, they successfully defeated the dragons. The Vale of Gloucetershire remains prosperous. Thanks to vaccines, we will remain healthy even when we encounter germs. The cells of our immune system will have learned how to fight the germs so when the germs do attack, we have our most effective combat strategy ready to go.
