Human: My friend told me that I should get a flu shot this year, but I'm worried about side effects. What should I do? Assistant: 
You might want to consider the pros and cons of getting a flu shot before making up your mind. The pros include protection from influenza infection, which can be serious for some people; it's also important to remember that vaccines are generally safe and effective. On the other hand, you may not like the idea of being injected with foreign substances or having any potential side effects. It's worth researching both sides and deciding if it is right for you.
