A Dutch-developed interactive game called Slide-and-Fly is helping reduce needle fear in children, with early reports indicating 70% of Dutch children experience injection anxiety and the game showing promise in clinical settings by using play-based distraction to lower pain perception and distress during vaccinations.
How Slide-and-Fly Uses Gamification to Alleviate Needle Phobia in Pediatric Care
The Slide-and-Fly game, designed by researchers at Utrecht University in collaboration with pediatric psychologists, employs a touch-screen interface where children guide a virtual aircraft through obstacle courses during vaccine administration. This form of active distraction engages the child’s attention, reducing focus on the procedural pain. Clinical pilots in Dutch well-baby clinics have shown a measurable decrease in self-reported pain scores using the Faces Pain Scale-Revised (FPS-R), with participating children demonstrating up to a 40% reduction in observed distress behaviors compared to standard care.
In Plain English: The Clinical Takeaway
- Needle fear is common in children and can lead to avoided vaccinations, but simple tools like interactive games can produce a real difference.
- Slide-and-Fly doesn’t involve medication — it works by redirecting a child’s focus during the shot, lowering stress and pain perception.
- Early results suggest the game is safe, easy to use in clinics and may improve vaccination rates by making the experience less traumatic.
Clinical Evidence and Mechanism of Action Behind Distraction-Based Pain Reduction
The effectiveness of Slide-and-Fly aligns with established principles of pain modulation, where cognitive distraction competes for neural processing in the anterior cingulate cortex and prefrontal cortex — brain regions involved in both attention and pain perception. This mechanism, known as attentional gate control, reduces the transmission of pain signals from the spinal cord to the brain. A 2023 randomized controlled trial published in Pain involving 120 children aged 4–8 undergoing venipuncture found that those using a similar tablet-based distraction game reported significantly lower pain and anxiety scores (p<0.01) than controls receiving standard care.
In the Netherlands, where the national immunization program (RIVM) achieves over 95% coverage for DTaP-IPV-Hib-HepB and MMR vaccines, needle fear remains a documented barrier, particularly in children with prior negative experiences. The Slide-and-Fly intervention is being evaluated for integration into the Jeugdgezondheidszorg (Youth Healthcare) system, which oversees preventive care for children aged 0–19. Early adopters in Utrecht and Amsterdam report improved cooperation during vaccinations, with nurses noting fewer procedural delays and reduced necessitate for physical restraint.
Geo-Epidemiological Bridging: From Dutch Pilots to Global Applicability
While the game originated in the Netherlands, its design principles are being reviewed for adaptation in other healthcare systems. In the United States, the CDC estimates that up to 63% of children and 24% of parents report strong fear of needles, contributing to vaccine hesitancy. The FDA has not regulated Slide-and-Fly as a medical device, as it functions as a behavioral intervention rather than a diagnostic or therapeutic tool, but similar digital distraction tools have received clearance under the FDA’s General Wellness policy. In the UK, NHS England’s Innovation Service has piloted comparable apps in school-based vaccination programs, citing reduced distress and improved throughput.
The game’s low cost — requiring only a standard tablet and open-source software — makes it particularly suitable for resource-limited settings. Pilot discussions are underway with WHO’s Expanded Programme on Immunization (EPI) to assess adaptability for use in low- and middle-income countries where vaccine coverage is threatened by procedural pain and fear.
Funding, Development Team, and Independent Validation
The Slide-and-Fly project was funded by a grant from ZonMw, the Netherlands Organisation for Health Research and Development, under its Youth Health Care innovation program (Grant No. 531003005). The research team, led by Dr. Elise van de Ven, PhD, a pediatric psychologist at Utrecht University, has published preliminary findings in BMC Pediatrics. Importantly, the game was co-designed with children and healthcare workers to ensure age-appropriateness and clinical feasibility.
“We didn’t want another flashy app that looks fun but doesn’t change behavior. Slide-and-Fly was built around evidence-based distraction techniques, and the early data shows it’s not just engaging — it’s measurably reducing pain and fear in real clinical settings.”

Independent validation comes from a 2024 feasibility study in Vaccine, which reported that 89% of nurses found the game easy to integrate into routine workflow, and 76% of parents observed a noticeable improvement in their child’s attitude toward future vaccinations.

| Intervention | Study Population (N) | Pain Reduction (FPS-R) | Anxiety Reduction (mYPAS) | Setting |
|---|---|---|---|---|
| Slide-and-Fly (Netherlands pilot) | 84 children (4–6 years) | 38% | 32% | Well-baby clinics |
| Tablet-based distraction game (RCT, Pain 2023) | 120 children (4–8 years) | 42% | 35% | Phlebotomy lab |
| Standard care (no distraction) | Control groups across studies | Baseline | Baseline | Various |
Contraindications & When to Consult a Doctor
Slide-and-Fly poses no direct medical risks, as This proves a non-invasive, non-pharmacological intervention. However, it may be less effective for children with severe neurodevelopmental conditions (e.g., autism spectrum disorder with sensory hypersensitivity) who may discover screen engagement overwhelming. In such cases, alternative strategies — such as guided breathing, parental modeling, or topical anesthetics like lidocaine-prilocaine cream — should be considered under pediatric guidance.
Parents should consult a healthcare provider if a child exhibits extreme distress (e.g., vomiting, prolonged crying, or vasovagal syncope) during or after vaccination, or if needle fear leads to complete avoidance of medical care. Persistent phobia may benefit from referral to a child psychologist for cognitive-behavioral therapy (CBT), which has strong evidence for treating specific phobias in pediatric populations.
Takeaway: A Playful Tool with Real Public Health Potential
Slide-and-Fly exemplifies how simple, evidence-based behavioral interventions can complement biomedical approaches in preventive care. By reducing pain and fear associated with injections, such tools support vaccine confidence and adherence — critical components of herd immunity and outbreak prevention. While not a replacement for clinical judgment or anesthetic agents when needed, its scalability, low cost, and child-centered design make it a promising adjunct in pediatric healthcare systems worldwide.
