As a liver doctor who has treated patients with hepatitis B for decades, this change to the vaccine schedule is a mistake. The hepatitis B vaccine is safe and effective. The birth dose is a recommendation, NOT a mandate. Before the birth dose was recommended, 20,000 newborns a year were infected with hepatitis B. Now, it’s fewer than 20. Ending the recommendation for newborns makes it more likely the number of cases will begin to increase again. This makes America sicker. Acting CDC Director O’Neill should not sign these new recommendations and instead retain the current, evidence-based approach.
