PRNT is vital for several reasons: 1. Vaccine Efficacy: It helps in determining the effectiveness of a vaccine by measuring the immune response it generates. 2. Serosurveillance: PRNT aids in monitoring the spread of viruses within populations by identifying individuals with neutralizing antibodies. 3. Immunogenicity Studies: The test is used to study the immune responses elicited by natural infection or vaccination. 4. Epidemiological Research: PRNT provides data that can be used for modeling disease transmission and understanding the dynamics of outbreaks.
