On this week's episode, we emphasize again that vaccine hesitancy is a top 10 threat to global health. We jump in and review the first four myths we debunked last week: that vaccines cause autism, that vaccines actually cause the diseases they aim to prevent, that vaccines contain fetal tissue, and that vaccines contain toxins and harmful substances.

We then move on to discuss and dispel the next four common myths we hear: that vaccines only affect individuals and it should be a personal choice, that natural immunity is better than vaccine-acquired immunity, that hygiene and not vaccines are responsible for reducing disease rates, and that the vaccine schedule overwhelms a child's immune system. We discuss several sets of case study data that demonstrate the concept of herd immunity for population-wide disease protection, instances where hygiene hasn't changed but vaccines led to precipitous declines in disease rates, and a brief primer on immune system development and exposure to antigens during childhood.

We have lots more to cover, so there will be a part 3 to follow!
