This is my story: 

My son had the vaccine and after his second shot was complaining about a sore chest.

Ended up taking him to doctors. Doctor freaks out at how fast his heart was beating.

Straight to hospital for the night. Took bloods. Done all their tests etc, for them to say it's nothing / can't find any reason why his heart was beating so fast.

I know it was something to do with vaccine.

Not sure if he will have problems later from this.

I'm disappointed we rushed to get vaccine with so little tests and information about it .
