The Oxford women behind life-saving Covid vaccine trials
"We were privileged and lucky enough that we could do something."Three women who were involved in the development of the Oxford AstraZeneca Covid vaccine have told the BBC about the challenges they so vividly remember.Dr Parvinder Aley, Sagida Bibi and Hannah Robinson, from the Oxford Vaccine Group (OVG) spent up to 18 hours a day, seven days a week working on the clinical trials in 2020."Sometimes I couldn't go home for a week," said Ms Bibi, who was tasked with collecting blood samples from 12,000 participants while remaining a safe distance apart.
Ms Robinson, who moved into a camper van in the clinic car park during the trials, said: "It was literally all hands on deck, thinking 'just do what you have to do to get the vaccine licensed'."
Scientists at the OVG had developed a vaccine prior to March 2020 but had to rapidly speed up the testing and production schedule from years of trials, to just months.Dr Aley, who facilitates research on the development and implementation of vaccines, knew that the group had a serious task ahead when lockdown was announced.She recalls being told: "This is not about glory, it's about delivering."Measures like wearing masks and washing hands helped to slow the spread of the virus however Dr Aley said: "To get us out of the situation we were going to need to get a vaccine."That responsibility felt huge but also we know how to do that."
OVG had the expertise needed to test the vaccine but faced a difficult task - carrying out a clinical trial with more than 12,000 participants while complying with strict social distancing measures.Ms Robinson explained that the trial was mapped out in February 2020.She said: "I was trying to work out how we could see a hundred people a day for a trial."It was very quickly clear that it would be huge. In a matter of weeks it had grown from hundreds to thousands."Her role was demanding, so Ms Robinson made the decision to live out of a camper van on the premises. "Eighteen hour days wouldn't be unusual," she said. "It was seven days a week for sure."Despite this, Ms Robinson fondly reflects on the atmosphere."It was a good mood. People were tired but positive," she said.The team received many donations and gifts. They had little free time to do everyday activities like food shopping so key workers brought them food. So much food that a second fridge was purchased to store it all.
Ms Bibi worked in the lab during the trials, spinning blood samples from more than 12,000 participants. She said: "Even though we say 12,000 participants, when were collecting blood and spinning it down, you have to times that by five or six for the amount of sample tubes that you end up collecting per visit. "It's a huge number of samples you bank across all of these sites."Ms Bibi lives in Birmingham which made it difficult for her to go home when working in Oxford. "There were hard days when people were strained and upset or just tired and missing family."During the trials, she spent more time away from her family than ever before.
The work done by these women and their wider team has not gone unnoticed. Although it is no longer produced or licensed, more than three billion doses of the vaccine they trialled have been administered across the world.It was linked with a rare side effect that caused a type of blood clot that in November 2022 was associated to 81 deaths.All vaccines carry the risk of side effects and the chances of severe complication from Covid itself were higher.The University of Oxford says the vaccine saved 6.3m lives in the first year of the global vaccine rollout – the most out of all the vaccines in circulation at the time.And Dr Aley said: "The feeling of teamwork, the feeling of achievement, the feeling of impact was amazing, I don't actually know how to describe it."She received an OBE for her services to vaccination during the pandemic."I've got twin daughters and I probably slept more the year that they were born than that year", she said, adding that she felt proud that she could be a role model for her children."Not bad for a working class girl from an immigrant family from Wolverhampton."

Restrict shop-bought baby food, government tells parents
Parents should not rely on shop-bought baby food pouches as everyday meals, new government guidance is the first time the NHS website has published advice on commercial baby food, and follows an investigation by BBC Panorama which found baby food pouches from six leading UK brands failed to meet their key nutritional critical of the way companies market their products as healthy options, have welcomed the leading baby food pouches carry labels such as "perfectly balanced for growing babies" or "packed with goodness". 'It's about time' advice introduced The NHS Start For Life website, run by the Department of Health and Social Care, also now advises parents to check food labels and choose products with the least amount of sugar, and to not let babies or children suck directly from food pouches - which can increase their risk of tooth it also says they should not feed snacks to children under one. Baby food snacks - such as puffs and sticks - have grown in popularity in recent weaning expert and author Charlotte Stirling-Reed told the BBC it was "about time that this was addressed... because food pouches and commercial baby foods are used so much by parents. It was a real gap in the NHS advice until now."Dr Vicky Sibson, director of the charity First Steps Nutrition Trust which campaigns for improvements in shop-bought baby foods, told the BBC that without clear advice it can be "confusing for parents" when they see shop-bought products marketed as being "just as good" as homemade foods. In April, BBC Panorama looked at the baby food pouches of six leading companies. The products have become a staple for many households with babies and children up to the age of two or three. They are convenient and have long shelf experts believe the products should only be used sparingly, are not replacements for homemade meals, and can cause children health problems if used as their main source of this was put to some of the leading brands, the market leader Ella's Kitchen told the BBC it agreed with all three other brands featured in the investigation – Heinz, Piccolo, Little Freddie, Aldi and Lidl - said their products were intended as a complementary part of a child's varied weaning NHS Start For Life website also now states that parents should wait until their baby is around six months old before feeding them solid foods, even if labels say the products are suitable from four among the brands investigated by Panorama, the companies Piccolo, Ella's Kitchen and Aldi promote their fruit-based pouches to babies as young as four months, despite the NHS and World Health Organization saying babies should not be given solid food until about the age of six Panorama began its investigation, all three companies said they are rebranding their products as suitable from six months. Baby food regulations 'need updating' Dr Sibson believes the government should now look to introduce stronger mandatory regulations for companies producing commercial baby foods to improve the suitability of the products for young children and regulate how they are marketed to Department of Health and Social Care told the BBC "current laws already set strong standards for baby food and we support action against any products that don't meet them".The British Retail Consortium says companies "take great care to optimise the nutritional composition of these products. All products are clearly labelled so parents can make informed decisions when feeding their baby."

Cuts to UK's global vaccination funding would risk avoidable child deaths, experts warn
Any cut in UK funding to a global vaccination group would damage soft power and could make British less resilient to infectious diseases, as well as causing avoidable deaths among children, leading vaccine and aid experts have warned. Scientists including Sir Andrew Pollard, who led the development of the Oxford-AstraZeneca Covid vaccine, said a major cut in money for the Global Alliance for Vaccines and Immunisation (Gavi) could also make the UK less able to respond to a future pandemic. The Foreign, Commonwealth and Development Office (FCDO) has not yet set out its future funding for Gavi, a Geneva-based public-private organisation that has vaccinated more than a billion children in developing countries. The UK has previously been one of Gavi's main funders, providing more than £2bn over the last four years. But with the UK aid budget cut back from 0.5% of gross national income to 0.3% and the focus shifting towards bilateral aid the expectation is that there will be a major reduction at Wednesday's spending review. Pollard, who leads the Oxford Vaccine Group, said that as well as continuing to save lives in poorer countries, there was a self-interested case for continuing with similar levels of support. 'It's a safer place, obviously, for people who are in situations where they wouldn't have been able to access these vaccines without the government support, but it also makes it a safe place for us, because it's acting as part of the shield that we have against the spread of infectious diseases around the world,' he said. A number of the vaccines used by Gavi originated in the UK, Pollard said, such as a new vaccine for malaria co-developed by Oxford University, and this meant the expertise and infrastructure were in place when Covid descended. 'The Covid vaccine was developed on the back of years of funding, both from the UK funding sources of government, Wellcome Trust and so on, as well as international funders that put teams of people working on vaccines here in Oxford so we could then respond when a pandemic happened,' he said. 'If we weren't doing this type of work, having the infrastructure and capabilities in the UK, we wouldn't have been in a position to have such an impact so early in the pandemic against that virus.' Dr Sandy Douglas, senior vaccinologist at Oxford University's Jenner Institute, who led efforts to scale up production of the Covid vaccine, said Gavi was known as one of the most cost-efficient of all aid projects, with one estimate suggesting a child's life was saved for every £1,200 spent on it. 'There really aren't very many ways of spending money anywhere in the world that can save a child's life for so little money, and do it scalably so hundreds of thousands of lives, millions of lives, are saved over time,' he said. 'The withdrawal or reduction of British funding to Gavi is going to result in the avoidable deaths of many children. Labour played a leading role in establishing Gavi, and Gordon Brown designed the financing mechanism that helps it to operate. I think it's something Labour should be proud of, among its greatest achievements since the NHS, probably.' Moazzam Malik, chief executive of Save the Children UK, who was previously director general for Africa at the FCDO, said the UK had traditionally been 'a very active player' in multilateral aid efforts such as Gavi and the Global Fund, which focuses on HIV/Aids, tuberculosis and malaria. Pulling back from this would be noted internationally, he said: 'People kind of appreciate that leadership. And if the UK decides to take a much more limited position, what the world would see from that is a sense of the UK pulling back.' Gavi's statistics show that it has vaccinated more than 1.1 billion children in 78 countries in its 25 years of operation, preventing nearly 19 million deaths An FCDO spokesperson said Jenny Chapman, the international development minister and peer, had set out that 'global health is a priority for this government and is a key issue as we modernise our approach to international development. 'Whilst we would not comment on the size of future pledges before announcing them, we continue to work with our partners, including Gavi, on this crucial issue.'

Sir David Attenborough almost killed by faulty scuba diving equipment
To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Sir David Attenborough has detailed an unsettling incident in which he nearly drowned when scuba diving. The natural historian and broadcaster, 99, first appeared on screens in the 1950s, when he presented natural history programmes including Coelacanth and Zoo Quest for the BBC. His TV credits now span eight decades, with Sir David since presenting shows including Wildlife on One, The Blue Planet and Planet Earth, as well as the newly released film Ocean. However, he's now recalled a moment early in his career when he came close to a deadly situation. Speaking to Prince William at an event to promote his new documentary Ocean, Sir David was presented with an open-circuit helmet. Picking it up and putting it on his head, he spoke about testing a scuba diving outfit while filming on the Great Barrier Reef in 1957. 'When I put mine on for the first time I suddenly felt water and thought, 'this can't be right'. But by the time the water got about there I thought, 'I'm sure this is not right',' he said. 'Of course, you've got this thing screwed on top of you and you can't breathe or make yourself heard. I was saying 'get it off me'.' Sir David then spoke about the director leading the documentary initially refusing to take his concerns seriously. 'He grabbed it and said it was fine, but I again said there was a fault, and he put it on, and I'm happy to say, he went underwater and came up even faster than I did, because there was actually a fault on the thing,' he added. During the discussion Sir David also described his first dive as a 'sensory overload' and commented on how the reefs he first visited decades ago had now been devastated. 'The awful thing is that it's hidden from you and from me and most people,' he said. 'The thing which I was appalled by when I first saw the shots taken for this film, is that what we have done to the deep ocean floor is just unspeakably awful.' 'I mean, if you did anything remotely like it on land, everybody would be up in arms. If this film does anything, if it just shifts public awareness, it'll be very, very important, and I only hope that people who see it will recognise that something must be done before we destroy this great treasure.' The pair spoke as part of the promotional launch for Ocean, which sees Sir David 'drawing on a lifetime of experience to reveal Earth's most spectacular underwater habitats, showing that we're in the greatest age of Ocean discovery and highlighting its vital importance'. Sir David said he hoped the film could 'expose something new' and encourage viewers to act to save the destruction of the ocean. Despite his indelible impact on the world and environmentalism, last year his producer Mike Gunton told Metro Sir David hated being called a 'national treasure'. More Trending 'He hates it, by the way,' he said. 'I say hates it… If anybody says he's a national treasure, he sort of slightly raises his eyebrows and says, 'Really?' That's a generational thing.' When it was noted Sir David's work is of far greater importance than a title, Mike responded: 'You've hit the nail on the head.'
