Question

Why do you not want to be sick (ill) when you get a vaccine?

A) Infection may interfere with vaccine effectiveness
B) Illness increases the risk of an allergic reaction
C) Vaccines are not effective when the body is fighting an illness
D) Sickness can lead to vaccine-associated complications

Answer 1

If you get a vaccine when you are already sick, it can interfere with the vaccine's effectiveness, increase the risk of an allergic reaction, and potentially lead to complications.

Step-by-step explanation:

When you get a vaccine, you do not want to be sick or ill because:

1. Infection may interfere with vaccine effectiveness: If you are already sick with the disease that the vaccine is meant to protect against, your body's response to the vaccine may be weakened, reducing its effectiveness.
2. Illness increases the risk of an allergic reaction: Being sick can make your immune system more sensitive and reactive, increasing the risk of an allergic reaction to the vaccine.
3. Sickness can lead to vaccine-associated complications: When you are already sick, getting a vaccine can potentially lead to complications or worsen your illness.
