The following post is only related to the concept of irrational fear.
Allow me to correct you. Fear is not irrational 'per se'. Fear is what allowed humans to be still around because stopped them from poking around fiery beasts or jumping in a river or off a cliff.
What is irrational is how you react to such fear, and since the reaction depends on a number of parameters including education, personal experience etc. the concept becomes a little complicated, which in my opinion should keep people from making comments that sound rather tranchant (I do like the word, what can I say).
When I board a plane I know for a fact that something 'may' happen and I could not get to the other end of the trip. I still board the plane because I need to get to destination in a timely manner and I consider the chances of a crash fairly low.
I see vaccination the same way, the odds of a serious reaction or taking the illness after it is so low that it out weights those of serious consequences if exposed without being vaccinated. We (impersonal) can argue forever on how such odds are determined (and I personally believe there could be an argument to be made for various reasons). It's obviously easier to count the number of people who died in a plane crash during the last 20 years.
And it's more than one @Norm , not that big on research, uh?
To put it into perspective, would you bet every single possession that you and your family own on the fact that all the planes taking off a single airport for a year will all reach their destination without an accident? Keep in mind that you don't know any of the pilots, nor the maintenance guys that work in that airport or any other airport where any of those planes will be serviced and loaded, or the ability of any of the pilots that could be on a potential collision course with any of those planes during that time.
