On Wednesday's Backchat, we're talking about serious flu cases and calls for citizens to be vaccinated.

The medical sector is urging members of the public to get their flu jabs after an eight-year-old unvaccinated girl, infected with the influenza A virus, died last week.


A six-year-old girl is also seriously ill in hospital.


Figures show 36 people died of flu-related complications during a 10-day period earlier this month. It's believed immunity levels may have been affected by a relative lack of exposure to viruses over the past four years, because of anti-Covid precautions.


So has flu become more serious than Covid? We'll be talking to medical experts.


After 9:45, we turn our attention to the activity known as parkour, with a video circulating online showing a young man apparently leaping from one MTR platform to another, prompting authorities to launch an investigation into potential breaches of MTR by-laws.
