The ethics of refusing vaccination.

 This is shouldn't be complicated. If you want to be a functioning member of society you should take any vaccine for which you don't specifically have an elevated risk of harm from.

Why? If you don't, you may be the reason someone else dies.

You may also die. But, a common line tossed around about those refusing vaccination is that it is their lives and bodies they are putting at risk.

And that is false. Unless of course you also cease to wish taking part in society as a whole.

In short, in a free country, such as Canada you are free to do the things you wish. Including refusing vaccines... so long as that doesn't impact the constitutionally protected rights of others. However, choosing not to take a vaccine for a highly infectious disease which kill people and then going about in public as normal may not pass muster there.

At the very least, it should be clear that it is not ethical.

Furthermore, the risk from vaccines which are generally considered mandatory, FAR exceeds the risk of serious complications or death resulting from the vaccine.

So, ethics aside, it would be statistical lunacy to choose to risk the disease over the vaccine.
