Which is a typical component of rapid response vaccination during an outbreak?

• A. Delay actions until surveillance confirms escalation
• B. Vaccination of only individuals with known contacts
• C. Intensified vaccination campaigns targeting broad populations and contacts
• D. Rely solely on natural immunity

Answer: (C)

In an outbreak, the fastest way to halt spread is to rapidly boost immunity across the population. Intensified vaccination campaigns that reach broad populations and include people who have had contact with cases create a wide protective shield quickly, cutting transmission chains and safeguarding those at risk. This proactive, broad approach—often delivered as mass or rapid outbreak response immunization—drives up coverage fast and stops the virus from spreading. Delaying action until surveillance shows escalation gives the outbreak more time to propagate; vaccinating only known contacts leaves many exposed individuals unprotected; and relying on natural immunity means people must get sick first, which carries serious health risks. So, expanding vaccination to both broad populations and their contacts is the effective rapid-response strategy.
