Why are some people anti vaccine?

I just don't get why anyone would be against something that's been proven to save lives protect people from illness and has gotten rid of many diseases. Is it because they're pussies that are afraid of needles making excuses so as not to sound selfish? If that's the case stop being such pansies. It's just a little poke that you feel for no more than a few seconds. But seriously anyone that thinks vaccines injure or kill people are at best gullible and naive. At wurst complete retards. Not to mention murderers that engager many lives.

I really think there needs to be a worldwide vaccine and mask mandate and when needed lockdowns to prevent the spread of disease.
