Beschreibungen/Notizen

• [...]the measurement of immune responses of two vaccines that are conceptually different from each other in their antigenic composition require vaccine-specific assays. [...]using different blood sampling timing for each vaccine (four weeks after the last dose of active vaccination for Rotasiil versus eight weeks for Rotarix) is a methodological error in the immunogenicity evaluation. [...]the impact of post-vaccination blood sampling timepoint on antibody titers and subsequent seropositivity rates has been previously highlighted [3]. [...]information on timing of blood sampling for Rotarix is only provided in the last paragraph of the discussion.
