Pre-reading
Why do I have to get a flu vaccine every year?
Let’s read the passage and figure out the reason.
Fast reading
To prevent getting the flu, most people get a flu vaccine. However, unlike vaccines for viruses that rarely change, flu vaccines cannot protect us in the long term as flu viruses are constantly changing.
What’s the main idea of the passage?
It introduces the reasons why people have to get flu vaccines every year and why they can be difficult to get.
Specific reading
Read the passage in detail and answer the following questions.
1. Why can’t flu vaccines protect us in the long term?
(1) A person’s immune protection from flu vaccination declines over time;
(2) flu viruses are also constantly changing.
2. Why is it difficult to get flu vaccines?
Because the flu vaccine is in high demand and short supply. The timing of influenza vaccine production and distribution is unpredictable, thus the availability of the flu vaccine supply does not always coincide with peak demand.
3. What makes this year’s situation more complicated?
Because the upcoming flu season coincides with the COVID-19 pandemic, which could overwhelm hospitals, straining resources and healthcare workers’ time.
Post reading

2. The timing of influenza vaccine production and distribution is unpredictable, thus the availability of the flu vaccine supply does not always coincide with peak demand.
