Dr Michael Brady joins Dr Mike in the PediaCast Studio for a two-part series on childhood vaccines. Today we cover Hepatitis B, Diphtheria, Tetanus, Pertussis, Hib, Polio, Rotavirus and the Pneumococcal vaccine. We also explore how immunizations work, talk about herd immunity, and walk through a risk/benefit analysis of the vaccine decision. We hope you can join us!
