Understanding the science and latest guidance on infection protection and immune health in pregnancy and the newborn period

In today’s episode, we take on a challenging and timely topic: public trust in health communication, especially when high-profile figures make statements that conflict with established scientific evidence. Recent comments from Robert F. Kennedy Jr., now serving as U.S. Health Secretary, have generated widespread public confusion, with reactions from British scientists, global health agencies, and clinicians offering sharply contrasting views. Dr Eliz Kilich and, Dr. Lydia Yarlott, unpack four of the most debated claims—carefully, calmly, and from a British medical perspective: “Thimerosal should be banned from ALL influenza vaccines to protect children and pregnant women.” We explore what thimerosal actually is, its current use in the UK, and what the evidence shows regarding safety and the confusion with methyl mecury and ethyl mercury. We discuss why RFK has focused on this chemical in particular. “Paracetamol in pregnancy caused the autism epidemic.” We reflect on our latest dedicated episode and how risk is communicated to expectant parents. “COVID-19 vaccines are no longer recommended for healthy children and pregnant women.” We place this statement against the actual WHO recommendations, discuss how guidance evolves over time, and why differing national policies often have nothing to do with safety concerns. “VAERS and existing vaccine safety systems don’t work.” We examine how vaccine surveillance operates Listen now, subscribe DM us @CocoonedHealth on Instagram Disclaimer: Remember we are sharing our opinions and medical knowledge, and not associated with our affiliations.

Ep 25. “No Longer Recommended?” The Politics, Science, And Stakes Of COVID19 Vaccination In Pregnancy In 2025. Hosts Dr. Lydia Yarlott & Dr. Eliz Kilich are joined by Professor. Flor M. Muñoz — Associate Professor of Paediatrics, Infectious Diseases, and Molecular Virology & Microbiology, Baylor College of Medicine and Texas Children’s Hospital. Her work has focused on the evaluation of vaccine safety and efficacy in special populations including pregnant women, children, and people with compromised immune systems, as well as the epidemiology and treatment of respiratory pathogens including COVID-19 and influenza In 2025, the U.S. government — under the Trump administration — made a striking policy reversal: COVID-19 vaccines are no longer recommended for healthy pregnant women or children. But what happens when political tides shift faster than science? In this episode of Cocooned Health, Dr. Lydia Yarlott and Dr. Eliz Kilich sit down with infectious disease expert Dr. Flor Muñoz to explore the real-world evidence behind this decision — and why maternal vaccination may still play a vital role in protecting newborns. We unpack: How mRNA vaccine particles and antibodies behave in pregnancy and breastmilk — and what studies reveal about newborn protection. Why COVID-19 in pregnancy, while rarer now, still poses serious risks for some mothers and infants. The philosophical and political forces shaping vaccine guidance in the U.S., from public trust to populist skepticism. How global health programs like Gavi and WHO are responding when America — once a vaccine leader — changes direction. And, most importantly: While no longer routinely offered, what’s the evidence that COVID-19 vaccination in pregnancy may still bring benefits? Mercury derived thimerosal what is it for, and is it of concern? Disclaimer: Remember we are sharing our opinions and medical knowledge, and not associated with our affiliations.

Ep 24. Paracetamol in Pregnancy: Panic or Proof? Expert Guest: Professor Dimitri Siassakos In this episode of Cocooned Health, Dr Eliz Kilich and Dr Lydia Yarlott are joined by Professor Dimitrios Siassakos, a leading researcher in maternal-fetal medicine at UCL, to unpack the controversy surrounding paracetamol (acetaminophen) use in pregnancy. A new review published in Environmental Health has reignited debate by examining possible associations between paracetamol use and conditions such as autism and ADHD in children. U.S. President Donald Trump claimed paracetamol “is no good” for pregnant persons, sparking widespread concern online. Together, we explore: discuss the recent controversies surrounding the use of paracetamol during pregnancy, particularly in light of claims made by political figures. They are joined by Professor Dimitrios Siassakos, who provides insights into the safety of paracetamol, the research surrounding its use, and the potential links to neurodevelopmental disorders such as autism and ADHD. The conversation emphasizes the importance of understanding causation versus correlation, the risks associated with untreated fever in pregnancy, and the need for moderation in medication use. Paracetamol is considered safe for use in pregnancy. Recent claims about paracetamol causing autism are based on over-interpretations of studies. Fever in pregnancy poses significant risks that outweigh concerns about paracetamol. Find out what by listening. Causation must be proven correctly; correlation does not imply causation. Genetic factors play a major role in the development of autism and ADHD. Moderation in medication use is crucial during pregnancy. The Swedish study provides strong evidence against the link between paracetamol and autism. Learn more by listening Healthcare professionals should guide pregnant women on medication use. Pain management is important; women should not feel guilty for taking medication when needed. The narrative around paracetamol use in pregnancy needs to be clarified for public understanding +++ NOTE when using the term pregnant women, we also refer to inclusive of transgender who may also be pregnant and non binary individuals.

Episode 22: Do all fevers in kids need bringing down? Science, exceptions and the myths of fever in children. It’s one of the most common worries for parents — and one of the most misunderstood. We discuss fever myths and more providing clarity and discussion In this episode of Cocooned Health, Dr Eliz Kilich & Dr Lydia Yarlott tackle the biggest fever myths in children: ❓ Do all fevers need treating? ❓ Will fevers keep rising to dangerous levels if left alone? ❓ Does getting lots of colds mean a weak immune system? ❓ Should you always give paracetamol after vaccines? ❓ When should you given paracetamol / ibuprofen to children. What age is it not OK? Can you switch between the two? As we discuss in the episode: Note children > 1 year can tolerate fevers much more than adults and thus the fever number itself becomes less concerning than other features. In adults the normal fever ranges tends to be 37.8 -39.4 (103°F) whereas in OLDER children (over one year) this is a little higher 38 - 39.8. Note this is not a hard and fast rule and the most important feature tends to be other symptoms. KEY EXCEPTIONS where the NUMBER MATTERS: 1. Children under or 3 months old - any fever needs URGENT same day medical review (>38°C (100.4°F)) 2. Children under or 6 months old > 39°C degrees 3. Fever > 5 days. Should be improving in 2-3 days or with fever medication 4. Seek medical attention in an adult > 39.4. This episode does not specifically describe fevers in adults and is limited to a discussion around fever in children. We unpack why other symptoms with fever tell you more than just the fever itself. 💡 We’ll unpack what’s fact, what’s fiction, and what really matters when your child spikes a temperature. 🎧 Subscribe so as not to miss a new episode ✨ Don’t miss this myth-busting chat that could save you a lot of late-night worry!
