Influenza vaccination in liver transplant recipients
Background:
The immunogenicity of the trivalent inactivated influenza split virus vaccine (Infusplit SSW 97/98) containing A/Bayern/07/95 (H1N1)-like (A/Johannesburg/82/96 [NIB-39]), A/Wuhan/359/95 (H3N2)-like (A/Nanchang/933/95 [Resvir-0]), and B/Beijing/184/93-like (B/Harbin/7/94) hemagglutinin antigens was tested in liver transplant recipients (TXL-R).
Subjects And Methods:
Serum antibody titers were determined 21+/-2 days after a single vaccination in 62 adult TXL-R and 59 adult volunteers.
Results:
Protective postimmunization antibody titers for the three antigens were similar in TXL-R (protection rates 92%, 92%, and 95%) and the comparison group (97%, 100%, and 100%). Adverse reactions were mild and less frequent in TXL-R. A significant decrease of CD8+CD38+ lymphocytes after vaccination was found in TXL-R. No association between antibody response and age, gender, time interval since transplantation, anti-hepatitis B surface antigen immunoprophylaxis, or immunosuppressive medication was detected.
Conclusion:
Our results show that the vaccine is safe and effective and should be recommended to TXL-R.
