A parent expresses concern to the nurse that the child's regularly scheduled vaccines may not be safe. The parent states hearing reports that they cause autism. Which is the most appropriate response by the nurse?

Choice A reason: Advising a parent to delay vaccinations contradicts established immunization guidelines and may increase the child’s risk of preventable infectious diseases. This response also reinforces misinformation and does not address the parent’s concern with accurate, evidence-based education. Choice B reason: This response directly addresses the parent’s concern using factual, evidence-based information. Extensive research has demonstrated no causal relationship between vaccines and autism. Providing clear, accurate information helps reduce fear, supports informed decision-making, and maintains trust between the nurse and the parent. Choice C reason: Suggesting alternative immunizations implies that standard vaccines are unsafe, which is not supported by scientific evidence. This response may increase parental anxiety and contribute to vaccine hesitancy rather than correcting misconceptions. Choice D reason: While this statement attempts to emphasize the importance of vaccination, it is phrased inaccurately and vaguely. It does not clearly correct the misconception about autism and may confuse the parent rather than providing reassurance based on scientific evidence.
