Nanubot's main argument for why he voted no was because, if a doctor doesn't have the right to commit an abortion on a random pregnant lady, then a child does not need a vaccination. Gr8 reasoning there, m8
As I said in my comment vaccinating children affects more than the child being vaccinated. Not vaccinating someone puts other people at risk. Its no different from outlawing reckless driving, it doesn't just endanger the driver it endangers everyone around them
Samantha's argument is baseless. Vaccines do prevent the spread of diseases, not cause them. Do they always work? No, because vaccines basically prepare the immune system of who they are used on for a specific disease, so if the person is immuno-compromised they obviously won't help (its like giving weapons to an army that doesn't exist). We have empirical evidence to prove this.
