    摘要: Provided are mixed carrier, multivalent pneumococcal conjugate compositions comprising 21 different pneumococcal capsular polysaccharide-protein conjugates, wherein each of the conjugates includes a capsular polysaccharide from a different serotype of Streptococcus pneumoniae conjugated to either tetanus toxoid (TT) or CRM197, wherein the Streptococcus pneumoniae serotypes are selected from 1, 3, 4, 5, 6A, 6B, 7F, 8, 9N, 9V, 10A, 11 A, 12F, 14, 15B, 18C, 19A, 19F, 22F, 23F, and 33F, where the capsular polysaccharides of two of serotypes 1, 3, and 5 and one or both of serotypes 15B and 22F are conjugated to TT and the remaining capsular polysaccharides are conjugated to CRM197. Also provided are methods of producing the mixed carrier, multivalent pneumococcal conjugate compositions and methods of using the same for prophylaxis against Streptococcus pneumoniae infection or disease in a subject.

    摘要: The present invention relates to a yellow fever (YF) vaccine for use in a method for inducing a protective immune response against yellow fever, wherein said method comprises concomitantly administering said yellow fever vaccine to a human subject together with a tetravalent dengue vaccine which comprises a live attenuated dengue virus of each of serotypes 1 to 4. This invention also pertains to a tetravalent dengue vaccine which comprises a live attenuated dengue virus of each of serotypes 1 to 4 for use in a method of inducing a protective immune response against yellow fever, wherein said method comprises concomitantly administering said tetravalent dengue vaccine to a human subject together with a yellow fever (YF) vaccine.

    摘要: The present invention is directed to a method of booster vaccination and to a vaccine composition for use in such a method, for inducing in a human subject a neutralizing antibody response, wherein said subject has previously received a primary vaccination against each of serotypes 1 to 4 of dengue virus and was dengue naïve before said primary vaccination, said composition comprising a dengue antigen of at least one of serotypes 1 to 4 or a nucleic acid construct capable of expressing said antigens in the subject, wherein said booster vaccination results in a 2-fold increase in the neutralizing antibody titre against each of serotypes 1 to 4. The invention is also directed to a method of inducing in a human subject a neutralizing antibody response comprising the administration of a vaccine composition, or to a vaccine composition for use in such a method, said composition comprising a dengue antigen of each of serotypes 1 to 4, or a nucleic acid construct capable of expressing in said subject a dengue antigen of each of serotypes 1 to 4; wherein said composition is administered as a primary vaccination, followed by a booster vaccination, and wherein the human subject is initially dengue naïve.
