Understanding Yearly Data

•Spikes may reflect awareness: Years with unusual activity (e.g., pandemic) often see increased reporting.

•Dose volume matters: More vaccinations given in a year naturally leads to more reports.

•Reporting lag: Some events are reported months after they occur, so recent years may be incomplete.
