Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Identify major viral illnesses that affect humans
Compare vaccinations and anti-viral drugs as medical approaches to viruses

The Center for Disease Control and Prevention site that covers just about anything you'd want to know about vaccines and immunizations, including vaccine recommendations, immunization schedules, vaccine safety, the importance of vaccines and more. Large site with lots of links.

Using a website simulation tool, students build on their understanding of random processes on networks to interact with the graph of a social network of individuals and simulate the spread of a disease. They decide which two individuals on the network are the best to vaccinate in an attempt to minimize the number of people infected and "curb the epidemic." Since the results are random, they run multiple simulations and compute the average number of infected individuals before analyzing the results and assessing the effectiveness of their vaccination strategies.

In this simulation the learner will design a sequence of experiments to
generate a coronavirus vaccine.

This site from the Nobel e-Museum contains a speech, originally given in 1905, in which Count K.A.H. Morner praises Robert Koch for his contribution to the world of medicine and awards Koch with the Nobel Prize.

A very complete biography from The Nobel Foundation on the man who was the father of modern microbiology, Robert Koch.

This pathway introduces the concept of vaccination, how vaccines are developed, and the purpose of clinical trials during vaccine development. The coronavirus SARS-CoV-2—which causes COVID-19—serves as an example.
