Malaria vaccines approved first in West Africa
Health Check
Apr 19, 2023

More than a quarter of the world’s malaria cases happen in Nigeria according to the World Health Organisation. This week the country became the second, after Ghana to provisionally approve the use of malaria vaccine R21. Professor Matt Fox explains why scientists have called the vaccine a ‘world changer’. We hear from dementia nurse Kemi Reeves who supports people living with dementia in Los Angeles. Her project has recently been shown to reduce the cost of caring for people with Alzheimers. We also hear about a new piece of research from the UK showing that hearing aids may protect against a higher risk of dementia. As we learn more about ‘Long Covid’, we explore evidence that links breathlessness with having had disrupted sleep. And have you ever been told you grind your teeth? Author Naomi Alderman was shocked recently when visiting the dentist to be told she had a condition called bruxism and hadn’t even realised. We ask whether experiencing the Covid pandemic may have led to more of us griding and clenching our teeth.

Lack of evidence most IVF ‘add-ons’ improve fertility

Many people with infertility use in vitro fertilisation (IVF), however the probability of having a baby following IVF is only approximately 30-40% per cycle and decreases significantly with age. It can be a lengthy and expensive process. Providers sometimes offer ‘add-ons’, additional treatments that they claim could help patients conceive, which are themselves also usually expensive. In Australia, New Zealand and the United Kingdom more than 70% of patients pay for at least one of these add-ons. A new review published in The Lancet Obstetrics, Gynaecology, & Women’s Health journal has found that evidence on the benefits of these add-on treatments is unclear. Claudia Hammond speaks to Dr Sarah Lensen, Senior Research Fellow in the Department of Obstetrics, Gynaecology and Newborn Health at the University of Melbourne.

Joining Claudia from Ghana is genito-urinary consultant and HIV expert, Vanessa Apea. Claudia and Vanessa discuss a draft African Charter on Family, Sovereignty and Values, which claims that comprehensive sex education, as well as a range of sexual and reproductive health rights, are a threat to African families from foreign ideologies.

They also discuss a report from the Office of Inspector General of US Agency for International Development (USAID) which reveals that President Donald Trump’s administration has spent hundreds of thousands of dollars in storage and transportation costs for $9.7 million worth of contraceptives that are being stored in Belgium rather than distributed to the various low-income countries they were intended for. Many of the withheld contraceptives are now expired or unusable due to their removal from temperature-controlled storage.

We also hear from Health Check reporter Jane Chambers in the Chilean city of Valdivia, where wetlands are part of everyday life—and increasingly, part of people’s health. And we hear how faecal-microbiome transplants could improve the efficacy of some antidepressants in patients with major depressive disorder.

Health at the football World Cup

From heat exhaustion to dengue fever - monitoring public health risks at the biggest tournament in football history.

With millions of fans travelling to the USA, Canada and Mexico for the men’s football World Cup, Claudia Hammond speaks to Professor Rebecca Katz from Georgetown University in Washington DC who is the Director of the newly set up Health Security Operations Center, a surveillance hub to track threats to health, monitoring the risk of diseases such as measles, dengue and chikungunya.

With the World Cup coinciding with rainy season in Mexico, which also means mosquito season, our reporter Rogelio Navarro in Guadalajara brings us the latest on efforts in Jalisco state to prevent outbreaks of dengue which is transmitted by mosquitoes.

And the potential for health issues due to extreme heat has caused concerns amongst players, spectators and scientists. At the men’s FIFA Club World Cup in the USA last year Chelsea and Argentina midfielder Enzo Fernandez spoke out about the difficulties of playing in high temperatures. We hear from Norwegian international midfielder Morten Thorsby and Douglas Casa, CEO of the Korey Stringer Institute and Professor of Kinesiology at the University of Connecticut, who have written to tournament organisers, FIFA, calling for stronger heat protection measures for players and spectators.
