Iran was one of the first countries to be hit hard by the coronavirus. In the first population wide survey of infection rates in a Middle Eastern country, Iranian medical researchers now estimate that about one in five people on average were infected during its first wave in 18 cities in the country. But the rate varies enormously from city to city. In the city of Rasht, they estimate more than 70% of the population caught the virus. Claudia Hammond talks to Iranian infectious disease researcher

Are genetic therapies for sickle cell disease beginning to come of age? Claudia Hammond talks to David Williams and Erica Esrick of Boston Children’s Hospital about their promising results with a gene therapy for the disease in a pilot trial involving six young patients. Their report appears in the latest edition of the New England Journal of Medicine alongside encouraging results of a CRISPR gene editing therapy for sickle cell disease. Both approaches target the same gene – the result of which is

Milestone in HIV prevention for women

Health Check ·

2020/12/02

In the week of World AIDS Day, Health Check looks at what's being described as a milestone in the prevention of HIV infection in women. It is a form of pre-exposure prophylaxis (PrEP) - an injection every 8 weeks of a drug called cabotegravir. A clinical trial has been comparing it to a daily PrEP pill which is already known to be effective at preventing HIV infection. The injection regimen was about 90% more effective at shielding women from the virus than the daily tablet. The trial involves more

Another week, another Covid-19 vaccine success

2020/11/25

Oxford University and Astrazeneca announced interim results from the phase 3 trial of their coronavirus vaccine. The results are promising with efficacy scores ranging from 70% to possibly 90%, depending on the dose of the first of the two inoculations. This vaccine also remains viable when stored at refrigerator temperatures – a logistical advantage compared to the Pfizer and Moderna vaccines. Claudia consults Charlie Wheeler, head of vaccines at the Wellcome Trust, about how this vaccine may

Measles outbreak threat due to Covid

Health Check ·

2020/11/18

Global measles deaths were already at a 23 year high in 2019 after several years of inadequate immunisation levels in a number of countries around the world. The coronavirus pandemic looks set to make matters worse. The World Health Organisation is worried that disruptions to measles vaccination programmes this year in Africa have substantially raised the risk of large outbreaks in many countries. Immunisation coverage needs to be maintained at 95% or more to keep measles suppressed. Too many babies

Covid vaccine ‘90% effective’

Health Check ·

2020/11/11

Health Check examines the excitement around the preliminary announcement of 90% effectiveness of BioNTech and Pfizer’s Covid-19 vaccine in its phase 3 clinical trial. Claudia Hammond talks to Professor Gregory Poland, head of vaccine research at the Mayo Clinic in the United States about what we do and don’t know about the vaccine at this stage, and how the vaccine may be approved and deployed in the coming months. She consults Kalipso Chalkidou, Professor of Global Health Practice at Imperial

Covid-19 vaccines: Unknowns and dilemmas

Health Check ·

2020/11/04

Some of the first large scale trials of Covid-19 vaccines may report results to regulators in the next few weeks. These first results will reveal how effective these vaccines are at preventing mild Covid illness but they’re unlikely to tell us how good they are at preventing serious disease and death. Should governments permit wide scale vaccination of populations based on that level of data when this may compromise learning more about their efficacy? And might widespread deployment of first

Covid-19 plasma therapy trial results ‘disappointing’

Health Check ·

2020/10/28

For months now, many people hospitalised with Covid-19 have been given convalescent plasma – donated blood serum from people who’ve already had the illness. The hope has been that transfusing donated antibodies against the coronavirus will help to prevent deaths and serious illness. Convalescent plasma therapy received a high profile boost in the USA in August when the Trump administration announced emergency use authorisation for the treatment, despite the lack of robust evidence for its efficacy

Lighting the brain after birth

Health Check ·

2019/07/03

Claudia Hammond visits the Royal Society Summer Science Exhibition.Every year a minority of births goes wrong and the baby is deprived of oxygen, which can lead to long-term brain damage and conditions such as cerebral palsy. Early treatment can reduce the likelihood of permanent disability or even death, so a team at University College London have now developed a new portable device which uses harmless infra-red to detect signs of brain injury in newborn babies, minutes after birth. It is called
