Parents should be notified if more than what percent of children are not immunized?

• A. 5%
• B. 15%
• C. 10%
• D. 20%

Answer: (C)

Notifying parents when immunization coverage in a group drops to a level that creates risk is about preventing disease outbreaks by keeping vaccination rates high. The best threshold is ten percent, because once more than ten percent of children are not immunized, the chance of transmission increases and contacting families helps them catch up on vaccines and ensure accurate records. This proactive step supports the goal of herd immunity in settings like childcare or school, reducing opportunities for vaccine-preventable diseases to spread. Lower thresholds (for example, five percent) can be too sensitive and cause unnecessary alarms in smaller programs, while higher thresholds (such as fifteen or twenty percent) delay needed action and leave more children vulnerable.
