So..is this right?

Question

So is a vaccine an injected substance containing slightly "disabled" antigens, that act to stimulate the immune system to produce antibodies?

yesss.....go me haha

Answer 1

yeah, pretty close

a suspension of killed or live-attenuated microorganisms that when given by an appropriate route and in an appropriate number of doses builds a heightened state of resistance to a specific infectious disease

Answer 2

Yes. A vaccine contains the antigens in disabled form but are still under the radar of the antibodies as the antigens arent the actual things that cause the problems, they just let you know the bacteria is present.
Rather like a box showing the picture of a cake saying:inside.
When you see the box you start to salivate as the look of the cake is good but the box is really empty but you were prepared for the cake.

You probs didnt need all that but i like doing analogies.
