aSeasonal influenza immunization was recommended every year [40]. Pneumococcal immunization was evaluated with the 13-valent pneumococcal conjugate vaccine (PCV13) and the 23-valent pneumococcal polysaccharide vaccine (PPSV23); the recommended revaccination for the PPSV 23 was 5 years after the first dose, up to 2 shots in lifetime, and there was not a revaccination recommendation for the PCV13 [41, 42]. Zoster vaccination was evaluated with a single dose of the recombinant zoster vaccine; a second dose should be given 2–6 months later, up to 2 shots in lifetime [43, 44]
