When should you report to VAERS?

• A. Only severe allergic reactions.
• B. Only events within 48 hours.
• C. Any clinically significant adverse event that occurs after any vaccine licensed in the US.
• D. Only events that are proven to be vaccine-related.

Answer: (C)

VAERS is a national safety monitoring system that relies on reports of adverse events after vaccination to detect possible safety signals. The best rule is to report any clinically significant adverse event that occurs after any vaccine licensed in the US. This broad approach matters because not all events are caused by the vaccine, and some can occur days or weeks later; capturing reports of suspected associations helps public health officials identify patterns that need further study. It isn’t limited to severe allergic reactions, isn’t restricted to events within a short time window, and doesn’t require proven causality—the goal is to recognize potential safety concerns early.
