Dr Samara Linton reports on efforts by black doctors in the UK to overcome vaccine hesitancy in their communities.

The Biden administration is to rescind the USA’s Mexico City Policy which denies federal aid funding to organisations overseas that provide abortion counselling or services. The policy, also known as the Global Gag, prevented other family planning and HIV prevention services from receiving essential funding. Joy Phumaphi, former Botswanan health minister and now with the Partnership for Maternal, Newborn and Child Health talks to Claudia about the impact of the policy on the health and wellbeing on women and children in sub-Saharan Africa, and about the prospects for these services after the Mexico City Policy’s imminent demise.

A team of eye specialists at University College London has found that levels of air pollution typical of big cities around the world increase the risk of one of the commonest causes of age-related sight loss – macular degeneration, a progressive deterioration of the retina. Professor Paul Foster tells Claudia how airborne pollutants from traffic and industry can damage the eye.

Antimicrobial resistance in conflict zones

For the last few weeks, the news has been dominated by the situation in the Middle East. Joining Claudia Hammond is BBC Health Correspondent James Gallagher who speaks with Dr Antoine Abou Fayad, a microbiologist and medicinal chemist based in Beirut, Lebanon. He reveals that war, just like the ongoing conflict in the Middle East, provides the perfect storm to accelerate the spread of multidrug-resistant infections. And nobody is safe.

Following the recent meningitis B outbreak in the UK which has killed two people and led to the rollout of vaccines and preventative antibiotics, Claudia and James discuss how meningitis outbreaks are dealt with in the ‘meningitis belt’ - an area stretching across 26 sub-Saharan African countries and talk about a new vaccine aiming to stop deadly meningitis epidemics which has been confirmed to be safe following analysis of vaccination campaigns in Nigeria and Niger.

And India's snakebite crisis is killing near sixty thousand people every year, about six people every hour. Journalist Chhavi Sachdev joins us to discuss the progress of India’s National Action Plan to tackle snakebite envenoming which launched two years ago. Also, what time of day do you exercise? Well, a new study using Fitbit-derived heart rate data has found that people who regularly exercised early in the morning were significantly less likely to have coronary artery disease, high blood pressure, Type 2 diabetes or obesity compared with people who exercised later in the day.

Last weekend, Kenya’s National Environment Management Authority rolled out new waste management rules to better dispose of products containing plastic, but the new laws are expected to increase the price of sanitary pads by 20%. Global health reporter based in Nairobi, Dorcas Wangira joins Laura to unpack what these policies mean for the accessibility of sanitary products, and what alternative solutions are needed to balance access with environmental impact. They also discuss how a drug to treat Parkinson’s disease can be made from waste plastic bottles using a pioneering method.
