Henrietta Lacks died in 1951 from a virulent cervical cancer. A sample of those cancer cells was taken at the time, and the way they behave has changed medical science forever, contributing to everything from the polio vaccine to drugs for Parkinson’s and Alzheimer’s disease. As the WHO give a posthumous award, Claudia discusses how the Henrietta Lacks legacy raises issues of global health equity.Plus with a Malaria Vaccine given a historic green light by the WHO to protect children in Africa, what are the distribution difficulties in countries which carry the greatest burden of disease?And what’s behind the low rate of Covid-19 vaccinations in Taiwan? We hear from one resident about why she’s chosen to have a home-grown Medigen vaccine which hasn’t yet completed all its clinical trials – and another who wants to wait for an alternative. Scientists say that trials about to start in Paraguay should show whether it stimulates enough immunity to protect people in the way the AstraZeneca vaccine does.

Many people have struggled with their mental health during the pandemic, but still don’t always feel free to discuss it, especially at work. Stigma remains a problem and discussing your difficulties at all is off-limits. For many years in England a campaign called Time To Change tried to change attitudes and the evidence from that and other initiatives was used to launch campaigns in India, Ghana, Nigeria, Kenya and Uganda in 2019. Sue Baker, Mind’s International Health Advisor, and Rosemary Gathara, Director of Basic Needs, Basic Rights in Kenya discuss the findings of the campaigns with Claudia Hammond. Matt Fox, Professor of Global Epidemiology at Boston University in the US, joins Claudia to talk about the latest global picture of Covid, mask wearing at basketball games in the US and the Kindness Test. And they look at research that suggests too much free time is bad for us.Presenter: Claudia Hammond Producer: Erika Wright(Picture: A woman sitting in a room.

In 2020 Vietnam ran a successful track and trace system, with very few coronavirus infections and for a long time no deaths at all, while other countries had thousands. In 2021 things haven’t gone so well and since July strict stay at home orders have been in place in some cities. Nga Pham, a journalist from BBC World News, and software engineer Kevin Vu talk about what life is like in Hanoi and Ho Chi Min City.Dr Monica Lakhanpaul, Professor of Integrated Community Child Health at University College London, talks to Claudia Hammond about a mystery disease outbreak in the state of Uttar Pradesh in India. The symptoms are fever, joint pains, headaches and nausea. People born premature can have an increased risk of developing heart problems later in life. For the first time researchers have shown that breast milk can improve heart performance in premature babies. The new study was done by Afif El-Khuffash who looks after premature babies and is Clinical Professor of Paediatrics at the Royal College of Surgeons in Ireland. And Monica and Claudia discuss the latest research into long Covid in children.Presenter: Claudia Hammond Producer: Pam Rutherford(Picture: A resident rides her bicycle near a make-shift barricade in Hanoi during the lockdown to stop the spread of Covid-19.

When was the last time you did something really kind for someone or someone else did something really kind for you? Claudia Hammond and guests are looking at the place of kindness in today’s world, asking what it really means, what happens in our brains when we act kindly and whether there can ever be a role for it in the cut-throat worlds of business and politics. She hears what kindness means to people in Kenya, Chile and in the UK. And with many aspects of kindness remaining under-researched, with your help Claudia and Robin Banerjee, Professor of Social Psychology at the University of Sussex, are asking you to fill in the gaps by taking part in the Kindness Test.Presenter: Claudia Hammond Producer: Erika Wright

Trials have shown that cocktails of antibodies are effective against Covid, and one called Ronapreve has just been approved for use in the UK, following in the footsteps of Japan and the US. Claudia Hammond talks to Penny Ward, Professor of Pharmaceutical Medicine at Kings College, London, about how these monoclonal antibodies work and where they are best used, given that they are very expensive. The UN Refugee Agency and the International Organisation for Migration have called on governments to ensure that everyone is included in vaccination plans, including refugees and internally displaced people. Samara Linton reports on how undocumented migrants, in South East Asia and in the UK, are getting vaccinated against Covid. The increased heat we are experiencing with climate change is causing deaths in people with underlying health conditions. Professor Kristie Ebi of the University of Washington tells Claudia about what we can do to keep cool, in particular in places without air conditioning. And family doctor Graham Easton comments on these stories and discusses the relationship between Covid and heat.

Claudia Hammond and her studio guest global health journalist Sarah Boseley discuss the health impact of the fires that are raging in many places including Southern Europe and the US. Lizzie Crouch reports on the longer term physical and mental effects of fires on people who experienced them in Colorado last year. Two reports, from the Netherlands and the US, are published this week that highlight the lack of women in drug trials for heart disease. Heart disease is often thought to be more common in men than women but that isn’t the case and new drugs need to be tested on women as well as on men. As the Olympics comes to an end Claudia talks to Adrian Bauman, Emeritus Professor of Global Health at the University of Sydney, about if there is any legacy for the general public in terms of increased exercise and fitness. He has just published a paper in The Lancet exploring this question – and the answer is a no. And Sarah Boseley and Claudia discuss the case of Marburg Disease in Guinea, the first to be reported in West Africa.
