Persistence of the immune response after vaccination with the Japanese encephalitis vaccine, IXIARO (R) in healthy adults: A five year follow-up study

摘要

Immunization with the Japanese encephalitis (JE) vaccine IXIARO (R) results in protective neutralizing antibody levels for one year. Since persistence of protective titer levels beyond one year was unknown, a 5 years follow-up study was conducted. Additionally, data were stratified to compare the persistence of protective neutralizing antibodies against JE in people with or without tick-borne encephalitis (TBE) vaccination.
