I understand this mrna technology has been in testing for over a decade, but this specific vaccine was not tested on humans until it was released to the public for emergency use.  You can look at the vaers data and if alarms aren't going off in your head, like they are for so many people right now, then I do not know what to do for you.  If someone wants to be a part of the experiment, that is their choice.  I choose medical freedom, I choose not to until there is long term testing.  You do not know what you're exposing your kid to in the future, but I hope you can live with your own personal choice to combat a flu with a 100% survivability rate among healthy young children, regardless of the damage it may do.
