I don’t believe I have ever had the flu either. My dad survived the spanish flu pandemic & never had flu all his life. At 5 years old he remembers neighbors & a 5 year old across the street dying from the flu. When he got older (80’s)he started flu shots just in case. I got my first flu shot this year. Not elderly enough to die from it but joined the herd immunity. I had no reaction to it which probaly means I wouldn’t have gotten it anyway.
When I got my first cocktail of shots for going overseas I got very sick. Which leads me to believe there was something in there that could have killed me had I not been vaccinated and contracted it.
the meta study i mentioned earlier basically ahows that herd immunity is a myth, that in fact is oe of the conclusions of the study. if the difference between those that get a shot and those that don’t catching the flu is only 4%, the whole herd immuinty concept for the flu shot is shot down in flames.
