Exam Question: Compare the following graphs of cases of COVID-19, and deaths from COVID-19, in Gibraltar. As of November 2021, Gibraltar had a nearly 100% vaccine rate in its population.   Images courtesy of The Financial Times. Copyright 2025 by Dr. Jonathan A. Miller. All rights reserved. Online sharing or distribution is prohibited. For exam use only in BIOL& 260: Microbiology at Edmonds College. Outside help is not allowed. 1. Based on the information in these two graphs, how do you think the vaccination rate of Gibraltar in January 2021 compared with the vaccination rate in July 2021? Explain. Note that you do not need exact percentages (you cannot determine this from the information provided), but rather you should qualitatively describe (e.g., high, moderate, low, etc.) estimated levels of vaccine coverage. 2. Do you think the information in these graphs should make us optimistic, or pessimistic, about our ability to control the pandemic? Explain. Please number your answers 1 and 2 and explain briefly but thoroughly.
