The main message of the ad could be summarized as which phrase?

• A. I got my vaccine, so you should get yours
• B. Vaccines are harmful and should be avoided
• C. Vaccination is mandatory for everyone
• D. Vaccines are only for at-risk groups

Answer: (A)

The message the ad is trying to convey is a personal endorsement that encourages others to get vaccinated. When someone says, “I got my vaccine, so you should get yours,” it uses social proof—people are more likely to follow a behavior when they see others, especially someone relatable, doing it. This creates a straightforward call to action: if I did it, you should too. The tone is positive and aims to normalize vaccination rather than scare or mandate it.

That’s why this option fits best: it captures the ad’s goal of persuading a broad audience to vaccinate by presenting the speaker’s action as a model for others. The other framings—portraying vaccines as harmful, suggesting vaccination is mandatory, or restricting it to at‑risk groups—would shift the message away from a general, encouraging invitation to get vaccinated, which the ad communicates through a personal endorsement.
