Sequential administration group
The subjects receive injections of pneumococcal vaccine and influenza vaccine simultaneously. We use commercially available PPV23 (Pneumovax NP®, MSDKK, Tokyo, Japan) containing 25 μg each of 23 capsular polysaccharide types. We use Fluvic HA syringe® (Handai Biken Ltd, Osaka, Japan), quadrivalent influenza vaccine (0.5ml) of 2015/2016 season.
The subjects receive injections of pneumococcal vaccine 2 weeks after the injection of the influenza vaccine. We use commercially available PPV23 (Pneumovax NP®, MSDKK, Tokyo, Japan) containing 25 μg each of 23 capsular polysaccharide types.
