Harriet Belderbos
Harriet Belderbos is a digital editor at Open Access Government who focuses on health content, especially vaccines, childhood immunisation policy and practical health promotion frameworks. Her coverage stands out for its attention to how policy decisions and technical standards translate into real-world protection, logistics and patient safety. She combines clear explanations of official data with operational detail, giving readers a concise view of how health systems deliver care, rather than only reporting headline announcements.
Earlier meningitis B protection through childhood vaccination shows success
In her coverage of meningitis B vaccination, Belderbos explains how changes to the childhood immunisation schedule have strengthened early protection against meningococcal B disease. She sets out the move of the second meningitis B dose from 16 weeks to 12 weeks of age, highlighting that this adjustment brings forward immunity at a vulnerable stage of infancy. Drawing directly on provisional data from the UK Health Security Agency, she reports that nearly 90% of babies in England received their second meningitis B dose by six months of age in April 2026, an increase of 4.6 percentage points compared with the same period the previous year. She links these figures back to policy, showing how a technical timetable change delivers measurable coverage gains.
Belderbos also situates the meningitis B update within the wider childhood immunisation schedule, noting the introduction of a new appointment at 18 months for a second dose of the combined MMRV vaccine against measles, mumps, rubella and chickenpox. The piece is structured as a short, data-led explainer: it sets out what has changed, cites clear statistics and describes the impact on timing of protection. This format reflects her broader approach to health reporting, where she distils official guidance into accessible paragraphs that still retain specific numbers and concrete programme details.
The importance of cold chain management for maintaining vaccines
Belderbos’ article on cold chain management shows her focus on the operational side of vaccine delivery and the systems that underpin safe immunisation. She explains that vaccine effectiveness can be significantly compromised if integrity is not maintained throughout the cold chain, and then walks through recommended storage temperatures for different vaccine types, including those sensitive to freezing and vaccines containing viral or lyophilised strains. By spelling out ranges such as 2°C to 8°C and –15°C to –25°C, she brings technical guidance into a straightforward narrative that health professionals and policy readers can follow.
The piece highlights the role of hospital pharmacists in preventing errors, from storing vaccines in original packaging and separate containers to monitoring equipment for temperature excursions. Belderbos introduces concepts such as failure mode and effect analysis to show how risks can be identified across all stages of the supply chain, from manufacturing and transport to storage in healthcare facilities. She then connects this risk analysis to practical mitigation through protocols, staff training, temperature monitoring plans and digital data logger technology for precise tracking across the cold chain. The article concludes by stressing the need for integrated immunisation information systems and robust record-keeping, linking logistics, data and patient safety into a single operational story. This emphasis on process and systems is a defining feature of her health coverage.
Circle of Health©: A holistic framework for health promotion
Beyond vaccines and logistics, Belderbos also supports content on broader health promotion, such as the Circle of Health framework. In stakeholder material on Circle of Health, she presents an interactive, holistic framework for health promotion, positioning it as a tool to structure and communicate health priorities. Her role as digital editor brings this kind of conceptual model into the same space as policy and technical articles, giving equal weight to frameworks that help professionals design and discuss preventative health.
Through this work, Belderbos engages with health promotion not just as messaging, but as an organised, visual approach that can inform programmes and interventions. The mix of vaccine schedule analysis, cold chain operations and holistic frameworks shows that she treats “health” as both a clinical and organisational domain: protection depends on immunisation timetables, reliable logistics and clear, shared models of health promotion. This breadth shapes her suitability for stories that sit at the intersection of healthcare delivery, prevention and system design.
UKAEA implementing the UK's fusion energy strategy
Belderbos’ portfolio at Open Access Government also extends into research and innovation, including energy and emerging technologies. Her article on UKAEA implementing the UK's fusion energy strategy shows her engagement with complex, long-term national programmes, linking scientific development to government strategy. Elsewhere, she has covered UK government investment in quantum technology aimed at tackling crime, fraud and money laundering, timed to World Quantum Day, and written on digital forensics in the age of social media, indicating a sustained interest in how advanced technologies are deployed to meet public-policy challenges.
This cross-domain work underpins her health coverage by demonstrating comfort with technical detail and structured programmes, whether in fusion energy or vaccine logistics. As a digital editor who interviews project leads and curates science and policy content, she is used to translating specialist language into concise, accessible prose. That experience feeds into her health beat, where she treats immunisation schedules, cold chain systems and health promotion frameworks with the same clarity and attention to implementation as she brings to other areas of public-sector innovation.

Abida Tasnim
Abida Tasnim is a health writer for The Daily Star who focuses on clear, practical guidance that helps readers recognise risks early and act before everyday illnesses turn into wider public health problems. She reports on infectious disease prevention, using measles coverage to show how outbreaks start with individual decisions and behaviours, not just hospital statistics. Her work explains what happens during an outbreak and then anchors the story in simple steps people can take, such as avoiding crowded places when symptoms appear, practising good hygiene, and seeking medical advice early. She writes direct, action‑oriented health explainers that turn clinical questions about contagion and disease burden into everyday choices. Across her beat, she stresses early recognition, timely care, and prevention as the foundations of healthier communities.
Adrián Carballo Casla
Adrián Carballo Casla stands out for turning complex cohort data on ageing into clear, food‑level advice on what older adults should eat to protect brain health and slow chronic disease. He is a researcher in nutritional epidemiology focused on ageing and chronic disease prevention and a postdoctoral researcher in geriatric epidemiology at Karolinska Institutet, writing health explainers for The Conversation. He reports on how diet quality, especially Mediterranean and Mind‑style patterns, shapes dementia risk, grey matter loss and neurocognitive ageing, and how healthy versus pro‑inflammatory diets alter multimorbidity trajectories. His articles translate findings on flavonoids, polyphenols, folate, omega‑3 fats and dietary nitrates into specific food choices and small, practical changes. Much of his coverage is anchored in his own studies on multimorbidity, high‑risk older adults and tailored dietary recommendations, often syndicated to other outlets.
Ahmed Elbediwy
Ahmed Elbediwy brings a lab-based understanding of cancer biology and clinical biochemistry to public-facing health reporting, linking drug mechanisms and molecular pathways to everyday choices about medicines and products. He writes for The Conversation on weight-loss injections, cancer overdiagnosis and anti-ageing supplements, focusing on obesity medicine, cancer signalling, screening trade-offs, skincare and supplement science. His pieces on GLP-1 drugs such as Ozempic, Wegovy and Mounjaro explain why some people do not respond, how gut hormones and appetite signals work, and where psychological support and nutrition fit alongside prescriptions. He co-authors explainers on cancer risk and overdiagnosis and on whether supplements can reverse ageing, separating established knowledge from emerging research. An award-winning senior lecturer at Kingston University, he favours clear, structured explainers, careful definition of key terms and evidence-based appraisal over hype.
