ABSTRACT

Solid organ transplant (SOT) candidates may not be immune against potentially vaccine-preventable diseases because of insufficient immunizations and/or limited vaccine responses. We evaluated the impact on vaccine immunity at transplant of a systematic vaccinology workup at listing that included (1) pneumococcal with and without influenza immunization, (2) serology-based vaccine recommendations against measles, varicella, hepatitis B virus, hepatitis A virus, and tetanus, and (3) the documentation of vaccines and serology tests in a national electronic immunization registry (www.myvaccines.ch). Among 219 SOT candidates assessed between January 2014 and November 2015, 54 patients were transplanted during the study. Between listing and transplant, catch-up immunizations increased the patients' immunity from 70% to 87% (hepatitis A virus, P = .008), from 22% to 41% (hepatitis B virus, P = .008), from 77% to 91% (tetanus, P = .03), and from 78% to 98% (Streptococcus pneumoniae, P = .002). Their immunity at transplant was significantly higher against S. pneumoniae (P = .006) and slightly higher against hepatitis A virus (P = .07), but not against hepatitis B virus, than that of 65 SOT recipients transplanted in 2013. This demonstrates the value of a systematic multimodal serology-based approach of immunizations of SOT candidates at listing and the need for optimized strategies to increase their hepatitis B virus vaccine responses.
