Which term best matches the description of preventing disease by vaccination or education?

• A. Health Literacy
• B. Secondary Prevention
• C. Tertiary Prevention
• D. Primary Prevention

Answer: (D)

Preventing disease before it occurs is the focus here. Primary prevention aims to stop illness from arising by reducing risk factors and providing protections, such as vaccines that prepare the immune system to fend off pathogens and education that promotes healthier behaviors to avoid disease. The description matches this level because vaccination and education are classic strategies to prevent disease before it starts. In contrast, secondary prevention involves catching disease early to prevent progression (like screenings), and tertiary prevention focuses on reducing damage after disease is established (such as rehabilitation). Health literacy supports understanding health information but isn’t itself a prevention level, so it’s not the best match for this description.
