Long term population impact of seven-valent pneumococcal conjugate vaccine with a “3 + 0″ schedule-How do “2 + 1″ and “3 + 1″ schedules compare?

Differences in direct and indirect reductions in VT IPD with a “3 + 0″ 7vPCV schedule versus “2 + 1″ or “3 + 1″ were small. All 3 countries moved to 13vPCV by 2011; data post 13vPCV will be important to assess IPD impact using more similar baseline incidence and comparison periods.
