Due to a large number of requests, we're publishing an excerpt from Mark Susta's book "Public Health - A Systems Perspective" on vaccination and so-called herd immunity.

You'll realize, that the whole concept of herd immunity is based on post-infection or post-vaccination immunity. Since the vaccination for coronavirus SARS-2 is not available, and the post-infection effect remains unknown, essential prerequisites for the herd immunity strategy are not met. More in the chapter "Vaccinate or not - that is the question."

Please note that the published excerpt comes from the book manuscript for your personal reference and should not be distributed, copied or modified.
