The CDC’s reversal on newborn Hep B vaccination will harm kids. The birth dose protects all babies from highly infectious Hep B, which can lead to lifelong disease & liver cancer.

Let’s be clear: There’s no strong evidence linking either to autism. 8 out of 10 Americans trust their doctor for health advice. Trust them—not politicians—if you have questions.
