Hello, my name is Ms. Wroth.

Today we're going to be looking at the lesson called the Importance of Vaccines.

This fits into the lesson unit Staying Safe and Healthy: How Can I Avoid Harm? Now in this lesson, we're going to be talking about things that might make you feel worried or uncomfortable.

For example, we're going to be talking about serious diseases and illnesses and how we can prevent our bodies from being sick.

So for this lesson, it is recommended that you have a trusted adult with you before you continue watching.

Today's lesson outcome is I can explain why vaccines are so important.

Let's begin by taking a look at our ground rules together.

Laura says we should listen to others, and that means not interrupting when somebody else is speaking.

Andeep says we should respect privacy, and that means if somebody decides to share an experience or a story that we don't go and repeat it to somebody else outside of this lesson.

Jacob says no judgement , and that means if somebody does decide to share their own story or experience, that we don't judge them because of it.

And Izzy says choose your level of participation, and that means you can decide if you simply just want to listen or if you want to share something throughout the lesson.

All of these ground rules are here to keep everybody safe in today's lesson.

Here are today's key words.

We have disease, immunisation, and vaccination.

Disease means when germs gets inside your body and make you feel sick.

Immunisation is the way our body protects us from disease.

And vaccination means a medicine that can prevent some diseases and serious illnesses.

Let's see if we can spot these keywords in today's lesson.

Here is the lessons outline, and we're going to begin with what is immunisation.

Diseases are illnesses that make people feel very unwell and they are often caused by germs getting inside our bodies.

Germs produce toxins that can cause us to develop a fever, a runny nose, or tummy issues such as vomiting.

Immunisation is the way our bodies protect us from diseases.

Our bodies have an immune system which can fight off diseases when we get sick.

Dr.

Elsie says, "There are two ways we can get immune from certain diseases.

Either by natural immunity or by receiving a vaccination", which is also known as a vaccine.

Time for a check for understanding.

Fill in the missing word in this sentence.

Immunisation is the way our body, us from diseases.

Hmm.

What could that missing word be? Pause this video so you can have some thinking time.

Well done if you said protects.

Immunisation is the way our body protects us from diseases.

Natural immunity happens when we get sick from an illness like a cold, and our body fights it off.

After the illness, our body sometimes remembers the disease and is able to protect us from getting sick in the future.

Dr.

Elsie says, "Natural immunity doesn't happen with every illness, especially with more serious diseases." Vaccinations help to prevent some diseases and serious illnesses.

They are the safest and most effective way to prevent diseases.

Dr.

Elsie says, "A vaccine is a type of medicine.

They come in small injections or nasal sprays", just like in the pictures on your screen now.

Vaccines contain a very weak or inactive form of a germ that teaches our immune system how to fight diseases.

Dr.

Elsie says, "Vaccines are not strong enough to make you sick.

However, they let your body learn how to spot the disease and fight it off if we get sick in the future." Time for a check for understanding.

How do vaccines work? Is it A, vaccines contain a strong form of germ that causes us to get sick so our body remembers the disease? Is it B, vaccines contain a very weak or inactive form of a germ that teaches our immune system how to fight diseases? Or C, vaccines contain fake germs that teach our immune system to fight off diseases? Hmm.

How do vaccines work? Pause this video so you can have some thinking time.

Well done if you said B, vaccines contain a very weak or inactive form of a germ that teaches our immune system how to fight diseases.

Dr.

Elsie says, "It is still possible to get sick once we have a vaccine.

However, it is much less likely and the symptoms won't be as bad." Izzy's granddad says, "Dr.

Elsie gives me a flu vaccination each winter.

In the last couple of years, I've only had the flu once and I didn't feel too bad." Time for a check for understanding.

True or false: you are much less likely to get a disease if you have been vaccinated.

You can give me a thumbs up if you think it's true or a thumbs down if you think it's false.

Hmm.

You are much less likely to get a disease if you have been vaccinated, true or false? Pause this video so you can have some thinking time.

Well done if you said true.

Time for a task now.

Fill in the missing words in this paragraph to show your understanding of immunisation.

Pause this video so you can have some time to do the task, and then we will go through the answers together.

Well done for having a go.

Your completed paragraph should look like this.

Diseases are illnesses that make people feel unwell and they are often caused by germs getting inside our bodies.

The safest and most effective way we can become immune from certain diseases is by receiving a vaccination.

Vaccines contain a very weak or inactive form of a germ that teaches our immune system how to fight diseases.

Well done if you've got those answers correct.

We're now going to move on to the second and final part of our lesson.

Why are vaccinations so important? Vaccinations are important because they keep everyone healthy.

Dr.

Elsie says, "If lots of people get a vaccine for a particular disease, very few people will get it and spread it to others." Millions of lives have been saved by vaccinations.

Some diseases have even been completely wiped out because of vaccinations.

Doctor Elsie says, "Smallpox was a contagious disease that caused a skin rash and a fever.

Around a third of people who had smallpox died.

But because of vaccinations, smallpox has been eradicated since 1980", which means that you cannot catch smallpox anymore, and that is all because of people getting vaccinated.

Time for a check for understanding.

Why are vaccinations important? Is it A, because if lots of people are vaccinated, very few people will get a certain disease and spread it to others, or is it B, vaccinations help nurses and doctors become rich as they are very expensive, or C, vaccinations have eradicated some diseases and have saved millions of lives? Hmm.

Why are vaccinations important? Pause this video so you can have some thinking time.

Well done if you said A and C.

Vaccinations are important because if lots of people are vaccinated, very few people will get a certain disease and spread it to others.

It's also important because vaccinations have eradicated some diseases and have saved millions of lives.

Some people believe vaccines are harmful and do not understand how important they are.

They might believe misinformation or conspiracy theories about vaccines, which puts them at risk of developing serious diseases.

Misinformation and conspiracy theories are often spread online.

Dr.

Elsie says, "It is important to remember that vaccinations have been around for over 100 years.

Before anyone is given a vaccine, it is rigorously tested to make sure that it is safe.

There is no evidence that suggests that vaccines are harmful." Time for a check for understanding.

What could you say to someone who believed vaccines are harmful? Tell your partner your ideas.

Pause this video so you can have some thinking time.

Well done for having a go.

You could have said vaccinations have eradicated some diseases and have saved millions of lives.

Before anyone is given a vaccine, it is rigorously tested to make sure that it is safe and there is no evidence that suggests that vaccines are harmful.

Well done if your answers were similar to mine.

Time for a task now.

Alex is not sure why vaccines are important.

Write down two reasons why vaccines are important.

Pause this video so you can have some time to do the task, and then we will go through the answers together.

Well done for having a go.

Your answer could include if lots of people are vaccinated, very few people get a certain disease and spread it to others.

This will help save lives.

Vaccinations have eradicated some diseases like smallpox and saved millions of lives.

Well done if your answer was similar to mine.

This brings us to the end of our lesson.

Thank you for joining me today.

I've had a wonderful time.

Here is a summary of everything that we've covered today in the lesson.

Diseases are caused by germs getting inside our bodies and producing toxins.

Immunisation is the way that our body protects us from diseases.

When we get sick, our body will try to fight off the disease.

Sometimes our body will remember the disease and be able to fight it off in the future.

Vaccinations are the safest and most effective way of becoming immune to certain diseases.

Vaccines work by using a weak or inactive form of germ that teaches our bodies to protect us from diseases in the future.

Millions of lives have been saved by vaccinations.

If many people get vaccinated against a particular disease, very few people will get it and spread it to others, saving even more lives.
