A recent birth cohort study suggested that vaccinated children had higher rates of chronic issues like asthma, eczema, autoimmune conditions, and neurodevelopmental disorders compared to unvaccinated kids.
But here’s the thing — this isn’t a perfect study. It’s observational, not randomized. That means it can show associations, not causation. Families who don’t vaccinate often make very different lifestyle choices overall.
One big factor? Diet.
Parents who choose not to vaccinate are often the same parents who prioritize whole foods, avoid processed products, and feed their kids nutrient-dense meals. That alone dramatically impacts long-term health outcomes.
My take: It’s important for parents to acknowledge that this study was done and these are the patterns it shows — but also to understand the bigger picture. Children’s health is influenced by so much more than vaccination status: diet, sleep, movement, time outdoors, screen time, and overall lifestyle.
At the end of the day, no matter where you stand on vaccines, nutrition and wellness practices are the true foundation of a resilient immune system and lifelong health.
