Top 10 Facts About Vaccines

Do you want to learn about vaccines? Well you've come to the right place! Check out these 10 facts about vaccines...

1. Vaccines give you immunity to diseases.

Vaccines help your immune system to identify a disease.

Once it knows what it is dealing with, it will create antibodies ready for when the real disease takes over.

When you catch the disease, those antibodies will work to fight it off.

You will be immune, which means you won’t be able to catch it.

3. The first ever vaccine was made in 1796.

The first ever vaccine was made in 1796.

It was to prevent smallpox and was created by an English physician called Edward Jenner.

Edward worked out how to do this by taking some fluid from a cowpox blister.

He then got the fluid and scratched it into a boy’s (James Phipps) skin. This caused a small blister to appear, but it didn’t last for very long.

He then tried it again on James but with the fluid from smallpox.

The boy didn’t end up catching anything and this was when Edward realised that the vaccine worked.

10. Vaccines are approved after lots of testing.

When a new vaccine is developed, it goes through lots of testing to make sure it is safe.

First it gets developed in a laboratory and then tested.

It mostly gets tested on animals first such as mice, to check it is working.

Clinical trials will then start.

First it will be tested on a small group of people (up to 100). If that goes well, it will then get tested on a large group of people (several 100).

It will then be used on several thousand people.

After these tests have been successful, the UK government will look at all of the trial data and will then license it for use.
