Strep A vaccine developed by Queensland researchers

Queensland researchers have developed a vaccine for a widespread and potentially deadly bacteria in a world-first breakthrough.

Group A streptococci, more commonly known as Strep A, is a bacteria commonly found in the throat and on the skin.

In most cases, it causes a minor infection, but for others, it can trigger a very serious or sometimes deadly disease.

Meningitis, toxic shock syndrome, rheumatic heart disease and sepsis have been linked to the bacteria, with children and older people particularly vulnerable.

Mia Wilkinson is living proof of the impacts of Strep A and why news a vaccine has been developed is so significant.

The Queensland girl almost died in 2017 and now lives as a quadruple amputee.

"She'd developed Sepsis. She'd developed that from Influenza A, Influenza B, RSV and invasive Strep A bacterial," mother Mia Wilkinson said.

It has taken Griffith University researchers 30 years to get to this point.

Human trials will be conducted in Canada and the first person will be inoculated on November 21.

The vaccine is projected to be readily available in five years if no issues are identified in testing.

It will then be offered to the elderly, those at risk of disease and pre-school children.
