It depends somewhat on the age of the child. The most simple explanation for a child could be something like:
A vaccine is a medicine that can keep germs from making you sick. You take this medicine ahead of time, when you are not sick, so if the germ ever comes around, your body already knows how to fight it before the germ can make you sick.
The way it knows how to do that is with a vaccination. The vaccination shows your body exactly what that germ looks like. Then your body makes up some of its own medicine that can kill that exact germ. It keeps the medicine to kill that germ in storage. It will use it if it ever sees that germ trying to give you an infection.
This makes it all easier and quicker for your body to fight the germ before the germ can make you sick. It can do it faster after the vaccination because it already has the matching medicine stored up. It doesn't have to start from scratch.
It makes the body create memory cells for future infections.
OR
It creates a small infection to help the body fight later infections.

Yes, a small dog can die when receiving vaccinations. Any dog has a risk when getting vaccinated of dying. Vaccinations can also not work and therefore can cause issues where the dog dies.
So they don't unintentionally spread diseases that are dangerous and currently under control. Contrary to popular belief, there is no proven correlation between autism and vaccinations. So get your ****ing kids vaccinated!
Because when Edward Jenner invented the vaccination, no one knew how it worked or what the side effects and risks were, so everyone was very skeptical about vaccinations. When Pasteur discovered microbes, he found how they and indeed vaccinations worked, and from there calculated that vaccinations could work against other diseases caused by the various differtent microbes he discovered, by using weakened or dead microbe antigens to boost the immune system.
There are no vaccinations for HIV or AIDS.

Doctors that work with kids are pediatricians.
Vaccinations are acceptable by the Pentecostal church.
Polio, diptheria, whooping cough, tetnas, german measels and a booster in South Africa. This depends on the country you live in.
To explain idioms to kids, relate them to familiar experiences or objects. Break down the literal meaning and then explain the figurative meaning in a way that is easy for them to understand. Use visual aids or examples to make it more engaging for kids.
