Why isn’t SA Health investigating the massive spike in cardiac events in young South Australians

Why isn’t SA Health investigating the massive spike in cardiac events in young South Australians (https://youtu.be/vG8ay2jsdPs)?
In July 2021, cardiac-related presentations in South Australian public hospitals dramatically spiked in those aged 15-44 years!

From January 2018 they remained steady at around 1,100 per month but drastically spiked in July 2021 through November 2021 peaking at 2,172 per month, just as the injections were rolled out!

Watch as I advise the Senate about the shocking data I have obtained through freedom of information from SA Health.
