The indirect protection of adults as a result of pneumococcal conjugate vaccination of infants has been discussed from different epidemiological points of view. In some countries, including Italy, even after pediatric vaccination, vaccine serotypes are still responsible for most pneumonia and invasive diseases in the elderly. Although the Community-Acquired Pneumonia Immunization Trial in Adults (CAPITA) produced encouraging results, it has not showed the efficacy of the 13-valent conjugate vaccine in preventing pneumococcal community-acquired pneumonia regardless of the number of episodes and serotype. Addressing these points by monitoring the direct impact of adult vaccination in real life distinguished from the effects of herd immunity will assist public health decision-making on the most effective adult pneumococcal vaccination strategies.

Pneumococcal pneumonia prevention among adults: is the herd effect of pneumococcal conjugate vaccination in children as good a way as the active immunization of the elderly?

Abstract

The indirect protection of adults as a result of pneumococcal conjugate vaccination of infants has been discussed from different epidemiological points of view. In some countries, including Italy, even after pediatric vaccination, vaccine serotypes are still responsible for most pneumonia and invasive diseases in the elderly. Although the Community-Acquired Pneumonia Immunization Trial in Adults (CAPITA) produced encouraging results, it has not showed the efficacy of the 13-valent conjugate vaccine in preventing pneumococcal community-acquired pneumonia regardless of the number of episodes and serotype. Addressing these points by monitoring the direct impact of adult vaccination in real life distinguished from the effects of herd immunity will assist public health decision-making on the most effective adult pneumococcal vaccination strategies.
