I would love to know the ages and occupation of all of you that makes these claims of never having the flu.
My guess is that your occupation does not put you in contacts with the great unwashed masses of a modern urban setting.
My other guess is that a lot of you that got sick from the flu got the shot after your were already infected and you thought you would knock it down. Your immune system laughed at your ignorance.
Finally, if you are retired and spend time at home, you wont get exposed.
Here is a reason medical workers are mandated to get the vaccine: To protect us from YOU bad mistakes.
Real reason medical personnel are mandated..? $$$$$
