16 splenectomized adults, all vaccinated with a 14-valent pneumococcal vaccine (Pneumovax) 1978-79 had their pneumococcal antibody concentrations measured before and up to 10 years after vaccination. The antibody concentrations after vaccination declined to 71% in 2 years and remained at this level during the 10-year study period. Further studies are needed to see whether this applies to all vaccinated splenectomized adults.
16名接受脾切除手术的成年人在1978 - 1979年期间均接种了14价肺炎球菌疫苗（纽莫法），在接种疫苗前以及接种后长达10年的时间里对他们的肺炎球菌抗体浓度进行了测量。接种疫苗后抗体浓度在2年内降至71%，并在为期10年的研究期间维持在这一水平。需要进一步研究来确定这是否适用于所有接种疫苗的脾切除术后成年人。
