From the calendar

Official source · Faculty of Arts & Science

Students will be introduced to the basic concepts of immunity to infectious disease and how breakdown of the immune response can lead to auto-immunity. We will trace the history of current ideas in immunology and the immune response by examining how bacteria and viruses cause disease and the initial discoveries that led to such developments as vaccination. Current topical and newsworthy infectious diseases (HIV, tuberculosis, SARS, avian flu) will be used as examples of how the immune system copes with microbial infections.

Prerequisite: None listed
Contact hours: 24 lecture; Total scheduled hours for the course, not per week.

n = 5student contributedSt. George offerings only

This is a student-contributed aggregate, not an official University of Toronto record. It is also not a measure of how hard the course is — a course average moves with who enrols in it, not only with the material.

The newest observation is from Winter 2023. Instructors, weighting and exam format may all have changed since — treat this as history, not a forecast.

Per-term figures stay hidden until each term clears five contributors. 5 observations can support one honest number; they cannot support 5.

Assessment weightingNo syllabus we can lawfully use has been verified for this offering. Contribute yours and the breakdown appears here.

A current averageThe newest verified observation is from Winter 2023. Later terms have no confirmed result yet.

Per-term breakdownHeld back deliberately. Splitting 5 observations across terms would be false precision.

Instructor-level detailAverages are not split by instructor. At these sample sizes the difference between sections is noise, not signal.

Archive coveragePyko holds no past paper for this course. We do not host or distribute course files in any case; the archive is what lets these pages describe how a course is assessed.
