Author of the “Let’s Be Critical Thinkers” children’s book series, Dr. Shannon Kroner, is raising awareness about the potential dangers of giving Tylenol (acetaminophen) to children following vaccinations. Dr. Kroner warns that while many parents reach for Tylenol to ease post-vaccine discomfort, research has shown that it may interfere with the body’s natural immune response, potentially reducing vaccine effectiveness and increasing the risk of adverse effects. She emphasizes the importance of informed decision-making, encouraging parents to consult with healthcare professionals and explore safer alternatives for managing post-vaccination symptoms.
