The World Health Organisation and UNICEF say global immunisation services reached 4 million more children in 2022 compared to the previous year, after a huge backslide during the Covid 19 pandemic. But the progress in countries like India and Indonesia masks continued decline in many lower income countries. Global health expert Tabitha Mwangi and Claudia Hammond discuss how immunisation numbers can bounce back. They also look at new research from Sub-Saharan Africa that suggests as many as one in 10 teenagers might have high blood pressure, and what might be the most effective way of lowering it? While you may be gripped by the action from the Women’s football World Cup in Australia and New Zealand, Dr Kerry Peek is keeping a careful eye on the games for health reasons. She’s one of a team of ‘concussion spotters’ deployed this year for the first time at the tournament. Claudia asks her why professional sports women are more at risk from head injuries than men. And are you a perfectionist? Psychologist Dr Thom Curran says striving to be perfect could put our mental health at risk.
