Around the world, the Covid pandemic is as deadly as ever. Vaccines are widely available in some countries, and completely out of reach to others. Here at home, tens of millions are refusing to take the vaccine, violent protests are erupting at school board meetings and even children’s hospitals against mask mandates, and more than 630,000 Americans have died from the disease.

To discuss all of this, we’ve invited Dr. Peter Hotez back on the show. Dr. Hotez is an infectious disease specialist and Dean for the National School of Tropical Medicine at Baylor College of Medicine. He and Alyssa Milano have worked together around the world for years, and he is one of the leading experts in preventing infectious diseases.
